Complete Guide to your Dremel Tool and Dremel Attachments. Dremel metal grinding bit

The Ultimate Guide For Dremel Bits – All Dremel bits explained

So, you bought yourself a Dremel. And since Dremels almost has unlimited uses it can be confusing to know what bit does what. At least I was confused when I first bought mine. I used grinding bits for woodcarving and didn’t even know how to lock the bit properly into place. At one point the bit came shooting out of the Dremel at me because I didn’t secure it properly.

Dremel bits can be used for grinding, polishing, cutting, wood carving, engraving, sanding, cleaning, grout removal, sharpening, routing, drilling, and much more. You can even make your own Dremel Bits.

All Official Dremel Bits are identified by a unique number. So I will add an # followed by a number referring to the bit throughout the article. This makes it easier for you to search up and find out more about the bit I am talking about.

If you want to learn more about the bit just google “Dremel number”.But let us end the confusion of Dremel bits. So you know what you should use for your next project.

The Collet For Your Dremel

The Collet is a tiny metal thingy that sits underneath the nut at the front of your Dremel or rotary tool. The job of the collet is to tighten around the bit and secure it in place. Some bits have different shank sizes which means that you sometimes have to change the Collet depending on the shank size of the bit.

The most common size for a Collet on a Dremel and rotary tool is 1/8″ ( 3.2mm) but Collets are also found in sizes 1/32″, 1/16″, and 3/32″.So if your bit keeps falling out of your Dremel or it won’t fit inside, you might need to change the collet to make it tighter or free up some space.

If you get tired of changing collets all the time there is an alternative. The Dremel Quick Change Chuck makes it easier and quicker to change different types of Dremel bits.

Sanding Bits for Dremel

The Sanding bit is the bit I use the most for my Dremel. Sanding bits comes in many different sizes and shapes and can be used on most materials. The Sanding drum is the most commonly used sanding bit. Sanding drums have inexpensive removable sanding bands that can be switched out when they are worn out.

You can get sanding drums in many different sizes, but I find it useful to have one small #431 ( 1/4″ or 6,4mm ) and a large one large #432 ( 1/2″ or 13mm). A great tip is to buy a bunch of cheap Sanding drums and Sanding bands on Amazon, they wear out quicker than the higher quality ones but you will always have a backup to change to.

Another Sanding Bit is the sanding disc #411, the sanding disc is attached to a Mandrel #402 This is a flat sanding disc that can be used for sanding down surfaces and even sharpening knives. I find this bit less useful than the sanding drums. But it can still be useful depending on your needs.

Cleaning/Polishing Bits For Dremel

There are several cleaning and polishing bits for the Dremel. They come in ranges from course metal brushes to soft polishing pads.

The Flat Bristle Brush #403 and The Cones Bristle Brush #404 are great for cleaning and polishing precious metals like silverware and deburring metal edges. It does the job for most metals and can also be used with a polishing compound. The design also makes it useful for getting into grooves and cracks.

The Carbon Steel Brush #428 is a rough brush designed to remove rust and clean up tough surfaces. When using the Carbon Steel Brush it will leave a matt finish that will have to be worked with finer brushes if you want to make the surface shiny. This brush is for those hard to get rid of spots.

For those smooth polishing finishes, Dremel has provided us a bunch of different polishing wheels and pads. I will group these together since it is only the shape that divides them. The Felt Polishing Wheel #414, Polishing Point #422, and Polishing Wheel #429 are great for use on metals to get a shiny and smooth finish. They are attached to a Mandrel #401 and easily removed and changed.

For smooth polishing, you will usually use a polishing compound. The polishing compound is in the center of the picture above.

Engraving Bits For Dremel

Engraving is another great use for the Dremel. When engraving we need strong and durable bits that cut and etch into hard materials.

Diamond bits are used to engrave glass, metal, and stone. Carbide burrs are used to engrave and work with metal. The most used bits for engraving are diamond bits. They are durable, can cut into hard materials, and are actually pretty cheap.

Dremel has “some” official diamond bits that are designed for engravings like the #105 and #107 diamond bit. But I would recommend buying some off-brand diamond bit sets of Amazon when starting engraving with a Dremel. There are so many more choices there.

Diamonds bits come in all different sizes, shapes, and grits. Make sure you choose the right one for your project.

Carbide burrs can also be used for engraving. These are more heavy-duty than the diamond bits and are mostly used for engraving in metals and working with metals. Carbide burrs are highly durable and can be bought fairly cheap on amazon.

Cutting Bits for Dremel

Dremel has its own cutting discs for cutting metal, wood, and plastic. Always wear eye protection when cutting with a Dremel.

For Cutting Plastic we use the Plastic Cut-off Wheel #SC476. This is a great and durable bit for cutting plastic and is used with a Mandrel #SC402.

For cutting metal, there is a couple of options. We can use the low-quality Cutting Discs #409 #420 #540 for the Dremel. The low-quality cutting discs are used with Mandrel #402 and break easily.

I recommend using the Fiberglass Reinforced Cut-Off Wheels #426 #SC456 which are much more durable, safer, and simpler to use.

For cutting wood we use the Wood Cutting Wheel #SC544. This is a great carbide wheel that can be used for small cuts in wood.

Grinding/Sharpening Bits For Dremel

Dremel has a huge range of sharpening grinding wheels and bits. These can be used for sharpening things like knives, chainsaw blades, scissors, and anything that needs to stay sharp. The grinding wheels come in all different shapes, sizes, and grit. I rarely use these since I have a grinding block, but they can be useful.

Sometimes you see this little strange block among your bits. This is a dressing stone for your grinding bits. The dressing stone is used to bring new life to worn-out grinding and sharpening bits. When the bits get clogged up with metal debris or become uneven just use the dressing stone and they will be as good as new.

Drilling Bits for Dremel

The drilling bits for a Dremel are used to make small holes. Dremels are really great for using small drills and making wholes that require precision. But Dremels can not use big drills because it does not have the power required and the collet is not big enough. The #628 Dremel Drill Set is great to have in your toolkit for your Dremel. But keep in mind that you will have to change collet whenever you change a drill bit. That is unless you have the Dremel Quick Change Chuck.

Routing Bits for Dremel

You can do some simple routing with a Dremel. The Routing Bits are uniquely designed to do routing and will most of the time be used for that. A great routing bit kit to get when starting is the Dremel 7 Piece Routing Bit Set #660. Dremel routing bits will be used with the Dremel Plunge Router Attachment #335 or the Dremel Shaper and Router Table #231.

Mandrel Bits for Dremel

There are some bits for the Dremel that are just used for securing materials that wear out frequently and need to be changed out, like sanding bands and polishing pads. These intermediary parts are called mandrels. The #401 mandrel is mainly used to secure polishing pads. The #402 mandrel is mainly used to hold cut-off wheels and flat sanding discs. The #SC402 mandrel is mainly used to hold cut-off wheels. The #407 and #430 is used to hold Sanding Bands Ex. #431

Best Wood Carving Bits For a Dremel

Wood carving is what I usually use my Dremel for. To add to the list I will add some of the best wood carving bits that are used for wood carving.

Kutzall Bits and Burrs are one of the best, if not the best bits on the market for wood carving with a Dremel. Kutzall bits are designed to last longer, cut wood fast, and require less cleaning than other burrs. Kutzall bits come in all shapes and sizes and are a must-have for anyone doing woodcarving with a Dremel. The bits can be quite expensive compared to other cheaper sets but they are definitely worth the investment. Here’s a link to Kutzall’s Website and their woodcarving bits.

Sanding Bits are surprisingly great for small wood carving projects like pendants and ornaments. You can use a coarse sanding Band for shaping and to remove a lot of material quickly or you could use a fine-grit sanding Band to clean up your wood carving and make it beautiful. I love sanding bands for wood carving because of their versatility and simpleness. Sanding bands are cheap and are simple to use.

The only downside with using sanding bands for woodcarving is that you become very bound to the shape of the sanding drum and have to make your object follow the shape of the drum.


Okay. So I know I said I was going to explain “ALL” Dremel Bits. But there is an unlimited amount of bits for the Dremel out there so that would be impossible. But I have provided an explanation of the most important categories of bits that are useful to know when getting to know the Dremel. So I hope you learned something from this article.

Here Are My Favorite Dremel Tools, Bits, And Attachments:

Recommended Dremel: The Dremel 4000 with Flex Shaft is the Dremel I recommend. It is a little bit more expensive than the Dremel 3000 but the powerful 1.6 amp motor of the Dremel 4000 is worth the extra money.

Affordable Dremel: The Dremel 3000 is an affordable option and is a good Dremel to buy as well. Just know that it comes with a little less power and runs at a little bit lower RPMs

First Accessory: The Quick Change Chuck is the first accessory I would get for the Dremel. This makes it so much quicker and easier to change bits.

Complete Guide to your Dremel Tool and Dremel Attachments

Over the years I’ve collected numerous amounts of handy hobby tools, all of which are useful and they all have their own purpose, but there is one tool that is probably more useful than most of the other tools put together and that of course is the Dremel Multi Tool.

There are many models of Dremel that shine through, notably the 3000 and 4000, but I have two Dremel 3000’s that I love, so this is the particular model that I’m referring to in the following guide.

Higher RPM, torque, and popular with hobbyists

The Dremel 3000, in particular, is popular with many hobbyists due to being lightweight and user friendly all around the house, studio, workbench and workshop. I recommend choosing a corded one rather than a rechargeable model. With a higher Speed (RPM) capability and higher torque, it shines through. Also, If you’re anything like me you may come to use your rechargeable Dremel multi tool and realise you forgot to recharge it. oops!

Hook to hang it up with, ideal to use with Dremel Flex Shaft

The cable is permanently attached and the power cord is about 6.5 feet long. There’s a hanging hook on the back so you can put this on a Dremel stand, hook or a nail if you want to hang it up. This is particularly useful not only for storage but also if used with the Dremel Flex Shaft attachment.

Pencil Grip, comfortable hold

The unit is very comfortable to hold and can be gripped as you would a pencil for fine intricate work, particularly if you have the flex shaft attachment. For fine engraving and carving work, this is a really comfortable way to work.

Who can use the Dremel 3000?

I highly recommend this model for hobbyists and beginner jewellers, beginner glass engravers, those wishing to carve stone, drill holes in beach pebbles, sea glass, beach pottery, broken china, and wood carvers. the list is endless. Great for DIY bits around the home and general craft work.

Another great advantage of the 3000 model is that when used with a Dremel Multi Chuck it is compatible with a wide range of bits, burrs and polishers, unlike the Dremel 290 engraver which is not. Read more about the Multi Chuck further on in the article, but suffice it to say this little Dremel attachment is an essential piece of kit.

Voltage and Plug

One last thing here before you purchase, and it may seem obvious, but do look out for the correct voltage and correct plug for the country you live in.

Changing Accessories on your Dremel Tool

Changing accessories is really simple. Make sure that the unit is not switched on and that it has stopped rotating. Press the spindle lock (the blue button), this will lock the spindle from rotating. Pop your accessory into the end. Keep the button pressed and tighten the accessory in towards yourself. Release the button. Make sure that it rotates freely.

The spindle lock unscrews and you can use this threaded connector at the end for attaching different accessories such as the Dremel Right Angle Attachment, Dremel Multi Chuck and Dremel Flex Shaft.

Advantages of the Dremel Multi Chuck

If you use your Dremel drill for various applications and will be changing Dremel bits and Dremel attachments many times then you will benefit greatly from making the small purchase of a Dremel Multi Chuck. This chuck will allow you to hold lots of different attachments with many different shanks (the shank is the bit that fits into your Dremel Multi Tool) and it makes changing your accessories super easy. You won’t have to change collets every time you use a drill bit or attachment that has a different shank for instance.

The Dremel Multi Chuck works with most models except the Dremel Engraver 490.

The above picture shows the following:

Using Your Dremel Rotary Tool

Whatever attachment you choose to use you should always start your Dremel drill off slow and build up to the speed that you want to work at.

Black nylon bristle brush

This Black Wheel Bristle Brush is really good for cleaning, and If you use a polishing compound with it you can use these for polishing. These are particularly great to use on intricate pieces of jewellery as it gets into all the difficult-to-reach areas.

Sanding discs

These little Sanding Drums are great for removing rust, paint, and heavy corrosion on metal, or for sanding and shaping wood, plastics and softer materials. They slide onto a mandrel and can be fitted on snugly by tightening the screw at the end with a screwdriver (you will have received one of these in your kit with the Dremel).

The kit comes with a couple of different grades of sandpaper sanding drums, but I recommend purchasing a couple of the rubber mandrels and then you can have them set up in different grades of sandpaper without having to change the grits every time.

Abrasive Discs and Cutting Wheels

The cut-off discs are hard, brittle abrasive discs. You can use these for cutting off the top of screw heads, and nails, or working with things such as minerals and plastics. Also supplied is the mandrel that these are designed to fit onto. When you attach the disc to the mandrel be sure not to over-tighten it because these discs are very brittle and will snap easily.

By purchasing different types of cutting discs or wheels you will be able to cut through a variety of materials.

Abrasive Stone

In this kit, you receive a very coarse orange abrasive stone. These stone burrs come in a vast assortment of different colours, sizes, grades, and different materials such as green carbide stone burrs, White Arkansas stone burrs and Pink Grinding Stone Burrs.

These are good for grinding and carving on harder materials like metal, ceramic, glass or even minerals and lapidary work on gemstones. I use the green silicon carbide stones a lot for shaping and filing silver and gold, and the Arkansas stones for smoothing metals. They are also very good for sharpening things.

Felt polishing pads

These are designed to be used with polishing compounds or diamond paste. The felt pads that come with your Dremel Tools attach to a little screw mandrel. I would recommend once these have run out to purchase mounted felt points as they are more robust. Other similar items you can try are a cotton buff or a calico wheel.

How to Use the Dremel 565 Multipurpose Cutting Kit / Router Attachment

Drilling with your Dremel Rotary Tool

Inside your kit, you will find a steel drill bit that can be used on soft metals, wood and plastics.

  • Diamond drill bits are for drilling holes in hard materials such as glass, stone, ceramic, bone, shell, pottery and china.
  • HSS (High Speed Steel) drill bits are for drilling soft metals
  • Carbide or TungstenCarbide Drill Bitsare for drilling through hard metals

The below image shows the Dremel 3000 with a Bottle Neck Diamond Core Drill. For these core drills and other diamond drill bits see our complete range here.

As I mentioned earlier, drill bits can be mounted on different sized shanks so if you’re looking to use your Dremel for drilling holes or drilling out a core you might want to invest in a Dremel Multi Chuck or Collet Nut Kit.

For more detailed information on how to drill using your Dremel Rotary tools have a read of a couple of our articles such as ‘How to Drill Sea Glass’, ‘How to Drill Pebbles’ and 4 Tips for Polishing Metals with your Dremel Rotary Tool

So there you have it, the Dremel 3000 and all its uses, along with a few of the accessories that come with it.

Why buy a Dremel Drill?

They are comfortable in your hand, well balanced and smooth. They don’t rattle and vibrate, and the quality is superb. Yours should last you for years!

Dremel Accessories

You will be astounded at some of the Dremel accessories that you can buy to fit into your tool. Apart from those mentioned above, there are many polishing abrasives, drills, burrs, stones, brushes, pads, silicone polishers, rubber burs and discs that will all fit into your new Dremel Multi tool, such as:

So whatever project you are doing and whatever material you are working with there is a burr or a tool that you can use with your newfound friend, the fantastic Dremel 3000.

This is just an introduction to what this tool can do, pick up yours and get experimenting!

Dremel Bits Guide: Rotary Tool Bits And Accessories Explained

In this article, you will learn about all the different bits and burrs used with the Dremel or similar rotary tool.

These bits are available from both Dremel and third-party manufacturers. There are bits for wood, stone, glass, plastic, and metal. So no matter what material you are working with, there are bits out there for it. In most cases, the same bit will work on multiple materials. I will mention this as we go along.

Years ago, when I was a complete newbie to Dremel and other rotary tools, I had purchased a complete set with many bits and burrs. As I explored materials beyond wood, I discovered the utility of bits that I had no clue about previously. This, in turn, opened up a whole new world of possibilities. This is the world that I am going to share in this article.

A Few Things To Keep in Mind

Please note that I use the terms bits and burrs interchangeably in some cases. A bit is anything that goes into a rotary tool. Some of these bits are also called burrs because they are very abrasive. Burrs are generally only used for carving soft materials like wood.

As far as I know, no one carves metal. It is much easier to sculpt it by cutting or melting it. However, you can always engrave it. Stone carving is very common but if you are carving something hard, make sure you are cooling your bit using water. Otherwise, it will overheat, degrade, and eventually fall apart mid-session.

Dremel has an excellent system of numbers and colors to segregate their various accessories. This is really helpful if you are trying to understand the 100 piece accessory kit that you recently purchased. However, in this guide, I will be covering all kinds of bits. Many of these are available from other manufacturers. I will not be referring to the Dremel colors and numbers.

The bits I am talking about are 1/8” in thickness which is a standard size for Dremel, and other rotary tools that use Dremel standard sizes.

So if you are ready to learn about all the different rotary tool bits that are out there, keep reading.

Dremel Bits For Wood

There is almost an endless variation of bits for wood carving. I know this because I have tried most of them, and my wish list is still extremely long! So I have divided them into


As far as Dremel the brand is is concerned, carving and engraving bits for wood are the same thing. However, there is a difference when you look at third-party manufacturers.

Engraving bits are smoother and are designed for precision. This is what you would use to create fine details or do calligraphy-inspired designs.

Carving bits are far more abrasive. They are designed to take more material off. Dremel calls them ‘cutting’ bits.

Here’s a good example of a set of carving bits.

complete, guide, your, dremel

The thing to note here is that you cannot shape a lot of wood with the Dremel set. You can do so with the previous set from Rokrou, a third-party seller. The finer tips on this set are great for fine engraving work. The larger stone-tipped bits are meant for metal, glass and stone. Not wood.

Here’s an example of what you should get for carving wood if you want to buy from Dremel only.

Depending on where you are, this may be called a “cutter”. Don’t be confused. Once you know what you are looking for, the image will be enough. The names might and will vary.

For carving, just get a set of various shapes when you are just starting out and build from there. Something like the example below.


Cutting wood with a Dremel is only feasible if you are cutting small pieces of wood. Otherwise, you are much better off using a coping saw or a similar saw. Dremel and other brands make HSS (high-speed steel) rotary blades in various sizes for cutting wood and other soft materials like plastic. Here’s an example

A set like this will last you a long time if you use it well. Make sure never to put too much pressure and avoid overheating. They won’t break but they warp and then they will wobble and not cut smoothly.

Make sure you follow the arrow and attach it properly so that it spins in the right cirection.


You can get two kinds of sanding bits for Dremel. There’s the drum type and the disc type. The drum type comes in three different sizes and the disc is usually one size only. See the examples below.

This is a good example of sanding drums in all their sizes.

This is what you will get if you are looking for sanding discs. This is just the regular hook and loop (AKA Velcro) system scaled-down the Dremel size.


Polishing for wood is done with felt-tipped bits. You will get them large collections of various sizes and shapes. A set like the one below will probably last you several years or several projects if used properly.

You can also get smaller sets when you are just starting out. Most large accessory kits will come with at least a few polishing bits.


There are special bits that are meant to be used either perpendicular or parallel to the surface of the wood. These are routing bits and they must always be used with the routing attachment. You can get a set with the attachment from third-party sellers like the example below.

You can also get Dremel branded attachments. If you are using a Dremel tool, it is better to get Dremel-made attachments. If you are using any other rotary tools, you can get one or the other. Most brands don’t last as long as a Dremel, with the only exceptions being Milwaukee and Proxxon. So you can base your decision on that fact.

Dremel Bits for Plastic

You can easily use all the bits for wood on materials like plastic and fiberglass. This is because they are equally effective when used on non-wood soft materials. However, for really soft materials, you should slow down the rotation speed. Otherwise, you run the risk of burning your material, which might produce toxic fumes. Too much speed will also ruin wood and produce burn marks.

complete, guide, your, dremel

So all the bits mentioned above will work for materials as hard as wood or softer. You can carve, engrave, sand and polish just like you would for wood. A few exceptions will remain, though. Make sure to do test runs before starting or committing to a project.

Dremel Bits For Metal


Dremel makes specialized stone-tipped grinding bits for grinding metal. These are useful for taking our burrs in your metal works, smoothening sharp or rough edges. They can also be used for sharpening edges on blades and things like chainsaws.

Dremel actually makes a special chainsaw grinding attachment and special bits for that purpose.

This kit is meant for all kinds of tools and not just chainsaws. Whether you are using a Dremel branded rotary tool or not, it is a good idea to buy a Dremel branded kit in this case because it is built to last. Garden tools can be rough on your rotary tool!

For starting out, you can get a third party set like this one right here –

The different shapes are helpful in different scenarios. The colors are indicative of use, and these vary from manufacturer to manufacturer. So you should read the user notes when you buy these bits.

Make sure to read up on the recommended speeds and stone types for different materials. These stones will eventually wear out with use, but they can wear out really fast if used inappropriately.


Dremel makes some of the best-reinforced cutting discs for metal cutting. With these cutting wheels, you can cut, trim, and groove various kinds of metal.

They might seem a little expensive upfront, but they are well worth the investment if you are working with metal frequently. The EZ lock system is a huge convenience for any rotary tool user, making it an additional benefit when buying Dremel.

You can also choose from resin-based cutoff wheels other than these fiberglass reinforced cutoff wheels. These tend to be a lot cheaper, but they also break easily. So they tend to come in large packs.

I can recommend a set like this one for beginners. It has cuttings wheels for wood, glass, and metal. That makes it really affordable. You will be breaking a few of these, and you don’t have to feel bad about it.

Learning can be a destructive process. Ask me, I have destroyed entire packs of these, and I am not sorry at all! I learned a lot in the process. Not I don’t break as many. I am still learning, you see!


Metal needs special abrasive wheels for polishing. These are designed to give a similar effect as sanding drums on wood. The only difference is the material. These are usually made of fine strands of metal, resulting in a fuzzy metal pompom of sorts!

The only thing to keep in mind when using these is to not apply pressure and turn the speed down all the way. Otherwise, they tend to explode all over the place. I am still finding strands of metal from one such incident months back!

These are cheap to buy in bulk, just like the sanding drums and polishing bits. You can get a pack of them like in the example below.

The colors are used to distinguish the abrasiveness of each type. That makes us rotary tool users a really colorful bunch! But then you already knew that, because you are one of us!

You can also use felt-tipped polishing bits for buffing your metal pieces. The same thing is done on a larger scale for buffing car bodies with large felt discs and polishing wax.


Metal engraving works the same way as metal grinding does. You get specially coated bits that will eat away at the metal as it turns. As long as you don’t overheat them through extreme pressure and/or speeds, they will produce good results.

This engraving and carving set from Dremel that I mentioned in the wood section are also rated for metal use. Read the instructions carefully, though, because they are usually meant for soft metals. Trying to engrave reinforced steel might call for some special grinding stones.

Fine tipped grinding stone bits are also excellent options for engraving metal. Just make sure that you can run them as cool as possible by using running water or dipping your piece in a pool of water while working.

If you are worried about decaying the metal, run it slow to keep it cool.

Dremel Bits For Glass and Ceramics

The keyword for glass cutting is “Diamond.” That’s right; these bits are all bling and fancy because they are coated with a fine layer of diamond dust. This is because glass and ceramic have hard physical attributes that resist cuts and scratches.

Diamond-tipped tools are the only things that can cut or scratch them. They come in different grits, just like sandpaper and whetstones. The range is between 40 and 600, where the higher the number, the finer the grit.


Any diamond-tipped engraving tool will work just fine for glass. Anything that works on glass usually works well on ceramics also.

Just like the carving bits for wood, the diamond-coated bits come in a wide variety of shapes and sizes. You can choose a large but cheap set for experimentation and then buy more expensive bits once you know which size you will be using the most.

This set from Dremel is a good example of a versatile kit at an affordable price. This is the third time it is appearing on this list. These tips are diamond coated and work well on all kinds of glass surfaces.

The larger ones are special abrasive stones that work well on glass, ceramic, metal, and a host of other materials. But they are not great for wood.


The same felt bits can be used for polishing glass because usually, you are just looking for some shine, not sanding.


Dremel and other manufacturers make diamond-coated cutting wheels, such as below. These will slice through the glass at moderate speeds. Always read the user notes for recommended rotation speed for every accessory that you buy. This way your accessories will last a really long time.

You can also get core cutting sets for cutting precise holes into glass and ceramic. Like the example below:

Dremel Bits For Stone

Shaping and engraving stone is slow, especially for harder stones like granite and jade. For this reason, you will want to start with softer stones like sandstone and perhaps marble.

Stones are pretty much like glass in this regard, and so you will need diamond-coated bits to make any headway into carving or engraving them. It is a slow process and requires patience and proper cooling, but it is gratifying to see what you have created out of a simple stone.

Thus, everything I have mentioned in the glass segment holds for stone carving, grinding, and engraving.

One word of advice – for larger pieces, you are better off roughing it out with hammer and chisel and then using the Dremel for the details, etc. Make sure you have running water or a basin to work with. This will help you keep the bit cool and prevent damage from overheating.

This part is not mandatory but removing debris constantly within something like rubbing alcohol is important for greater accuracy and smoother experience.

Also, resist the urge to increase the rotation speed. It will degrade your precision and damage the bit and possibly the design you are working on. It took thousands of years to form the stone you are holding. So a few extra hours to make art out of it is worth it.

Here’s a good diamond-coated bits starter kit with lots of variety.
