Chicago Electric Angle Grinder. Construction grinder

If you are serious about metal fabrication, DIY or even upcycling, you probably either own or have considered buying an angle grinder.

What is an angle grinder?

An angle grinder is a handheld power tool that can be used for a variety of metal fabrication jobs that include cutting, grinding, deburring, finishing and polishing. The most common types of angle grinder tools are powered by electricity; either corded or battery powered.

Which abrasives discs you select to use with your angle grinder depends entirely on your specific application and the material you are working with. Read on for more on this.

Why buy an angle grinder?

Versatile and easy to use

It’s the most versatile tool in the box and should be a staple of any shed or workshop but we aren’t just saying that because they work perfectly with many of our abrasives!

An angle grinder tool with the right disc can replace numerous tools and make the most tedious, labour intensive jobs quicker and easier.

Better yet, they are easy to control and any novice with the correct safety precautions can pick up an angle grinder and start working. This makes them perfect for DIY projects.

What is most common angle grinder size?

Angle grinder tools come in many different sizes, the most common size sold in the UK is 115mm. This sized model is light, precise and generally very easy-to-use; making it a great choice for the beginner and professional alike.

A wide choice of angle grinder models and brands available

Unlike a lot of specialist tools and abrasives, you can walk into any nearby hardware store in the world and find an angle grinder for sale.

There are huge number of different models and brands to choose from, at varying price points.

Your budget, your level of usage, and your experience should be the key influences over which angle grinder you purchase. Don’t go spending over the odds on a high-end model that’s only going to be used twice a year.

Which angle grinder disc do I need?

So you’ve purchased your angle grinder, now which discs do you need? In the first instance you need to determine the type of material you are working with – metal or masonry?

Then, what are you doing to the material, is it cutting, grinding, stripping, finishing, or all of them?

Angle grinder discs for cutting metal

These products can be very broadly categorised as either for cutting or grinding.

Cutting metal: Cutting Discs

Metal cutting discs are designed to cut through metallic items as quickly as possible.

The type of disc you choose will depend heavily on the hardness, thickness, and the metal itself.

For example, an entirely different disc would be required when cutting aluminium vs. cast iron as our application table shows.

Some of the more premium, sharper grained cutting discs also offer a higher level of comfort by reducing the amount of pressure required to cut through the metal.

Thinner cutting discs such as the Ultra-Thin range of 1.0mm and 1.3mm are ideal for metal pipes, thin gauge metals and tubular workpieces.

Logically therefore, a thicker heavy-duty disc is used for more robust pieces of metal where more stability is required.

Our top tier cutting discs are found in the Norton Quantum3 range.

With a self-sharpening ceramic grain, Norton Quantum3 discs are fast, effective, and comfortable to use; performing time after time.

Grinding metal: Grinding Wheels and Flap Discs

Whether you are preparing carbon steel for painting or finishing a weld seam. grinding wheels and flap discs are essential accessories for the angle grinder.

Selecting the right grinding wheel can be quite complicated and will depend heavily on the desired surface finish you require from your metallic workpiece.

A highly polished, decorative finish on stainless steel for example requires more steps and usually a higher degree of technique than simply roughing the surface of carbon steel to improve paint adhesion.

Why not read our definitive guide on choosing grinding wheels for more information?

Stripping metal: Stripping Discs

For stripping heavy coatings (such as paint or rust) from metal or wood, you will need to choose a coarse grit fibre disc, flap disc or Norton Rapid Strip disc.

chicago, electric, angle, grinder, construction

Depending on the condition and amount of coating to be removed from metal, you could opt for a coarse abrasive.

Starting with a coarse grit will allow you to strip the coating quickly and minimise loading of the disc, however it may impart deep scratches on the surface.

For rust removal, use a 60 or 80 grit flap wheel or Rapid strip disc.

Rapid Strip discs are particularly suited to removing rust and de-burring metal without damaging the workpiece itself.

Angle grinder discs for cutting concrete and masonry

Generally, a diamond blade would be the best choice for cutting concrete and masonry.

Unlike the cutting and grinding wheels for metal, a diamond blade is predominantly metallic product itself.

Its basic general structure is a steel centre with outer segments containing synthetic diamond fragments that give the blade abrasive qualities.

These diamond segments are ideal for cutting concrete, bricks, and building materials, and natural stone.

Once you’ve picked the right disc for your project, you just need to make sure you find the right size and speed for your specific angle grinder.

Why not try the Invincible Diamond Blade from Norton Clipper?

Setting the correct speed

Angle grinder discs have a maximum safe RPM that they should be operated at, which prevents them from breaking apart while in use and potentially causing an injury.

Make sure that your right angle grinder tool does not exceed the recommended RPM for the product you are using, bearing in mind that most right angle grinders run at a fixed speed of around 11,000 RPM.

Personal Protection Equipment

Once you’ve chosen the right angle grinder discs for your project, you need to prepare your work station.

Whatever you’re working on, you’ll be generating dust, flying debris and possibly even sparks.

To keep yourself safe, make sure you wear work gloves, a dust mask, safety glasses and a full face shield.

It’s also a recommended that your work somewhere that is properly ventilated, and always use the safety guard during operation to protect yourself.

In the extremely rare event of wheel breakage, the guard is designed to project all disc debris away from the operator, so always ensure no-one is in the potential path of debris if the worst would happen.

For the safest operation, we’d recommend that your angle grinder features a ‘dead man switch’ too.

This means you’ve got to keep the switch in the on position while in use, so if you were to let go of the grinder, it would switch off, reducing the risk of injuries.

Check the expiry date

Cutting discs and grinding wheels for the angle grinder have an expiry date which you need to pay attention to.

To find this, simply check the inner metal ring on the disc and look for a date stamped there.

Getting started

So now you have chosen the correct angle grinder discs for your specific application, safely set up your work station and taken all necessary safety precautions, below are some tips for how to work on each material.

How do you cut metal with your angle grinder?

When it comes to cutting metal, a right angle grinder saves a lot of time and effort versus using a standard hacksaw.

Ensure that you clamp the workpiece securely in a vice and select a suitable metal cutting disc.

Make sure each side of the cut is supported, so there is no possibility for it to move and ‘pinch’ the disc as you are cutting, potentially causing wheel breakage.

Hold the grinder tool straight and use light pressure to cut through the metal, let the cutting disc do to work, do not try to force it through the workpiece.

Move the disc backwards and forwards along the cut, take care not to twist the grinder as this will cause the disc to warp and bend.

Too much pressure will also result in the cutting disc wearing prematurely, which means you’ll be replacing worn out discs more often than you want to!

Cutting ceramic tiles, concrete and stone with an angle grinder

An angle grinder can be used to replace a larger tile saw to cut ceramic tiles, concrete paving stones, and many other types of stone.

For this type of work, you would need either a cutting disc that specifies use with masonry or (more commonly) a diamond blade.

Diamond blades often cost a bit more but will last significantly longer and cut faster.

Another handy use for the right angle grinder is cutting ceramic tiles.

For this application you will need to use a continuous rim diamond blade that is designed to cut through hard tile and leave a smooth cut.

An ordinary segmented diamond blade would be unsuitable for this kind of work as it would almost certainly cause a a rough, chipped edge.

When cutting paving stones, stone and tile, make sure the workpiece is secured before cutting.

Using light to medium pressure, move the grinder in a back and forth motion through the cut.

This helps remove dust from the cut and allows the wheel to cut faster. It is important not to twist the grinder when in use as this can cause the disc to warp and with some lower quality blades, the segments themselves to break off.

Review Summary

So here’s the story. I went to get my DeWALT 4 1/2 angle grinder repaired as the gears had finally given out, after many years of use. They wanted 50.00 to fix it, so when I saw these for 21.00, I thought I would give them a try (I bought two). That was ten years ago and these Chicago Electric grinders are still running fine, and I have put them through some heavy use.

If your still a doubter go to the Harbor Freight web site and read some of the 80 plus reviews that confirm my experience.

Angle grinders are electric power tools with detachable grinding wheels that you can apply to a variety of jobs around your home, including sanding, grinding, cleaning, and cutting. When using a grinder, make sure you’re picking the right attachment for the job and using that attachment correctly. Always practice safety procedures when working with a grinder, as it can cause injury, both from the blade itself and from flying debris. [1] X Expert Source

Choosing and Applying the Right Attachment for the Job

  • Try buzzing off dirt that’s set on garden tools. It will even work on set-on cement.
  • Pick the cup wire attachment for flat surfaces and the wheel to get into crevices.
  • Make sure to pick the right type of blade for the project you’re working on. For metal, a cutoff wheel works well, and it’s fairly cheap.
  • For masonry, tile, and concrete, choose a diamond wheel. Read the attachment to know what materials you can use the wheel on. [4] X Research source
chicago, electric, angle, grinder, construction
  • Don’t let the blade get too hot, as it will become very brittle. If it turns black or blue, give it a rest for a moment.
  • Check the wheel for the arrow showing you which direction it will rotate when on.

Operating an Angle Grinder Safely

Put on safety gear like goggles, long sleeves, and full-face protection. One of the main dangers of an angle grinder is flying debris, including pieces breaking off of the tool’s attachments. Protect yourself with safety gear so you don’t catch a piece in your eye. [7] X Expert Source

  • Put in ear plugs or cover your ears with noise-canceling earmuffs, as the sound from the machine can get very loud.
  • Wear a dust mask for particularly dusty jobs, like sanding and grinding mortar. [9] X Research source
  • Grab the handle with whatever hand feels most comfortable.
  • The deadman’s switch is a safety feature. If you accidentally drop the grinder, it will go off automatically.

Let the grinder come to full speed before applying it to the surface. Hit the power button to turn it on. Whether you’re cutting, grinding, or sanding, allow it to come up to speed to help you keep your actions smooth and consistent. For instance, if you’re cutting through metal or other materials, you’ll get a better cut if the cutting disc is at full speed first.

Move the angle grinder around constantly when sanding or cleaning. Don’t keep the tool in one place when sanding, as you could end up with gouges. For a smoother finish, move in a rotating motion over the surface. If you’re trying to smooth or clean one particular area, don’t hold it in place; just move it around and over the area until it’s to your satisfaction. [10] X Research source

  • With cutting, use the side of the wheel to cut the piece head-on, meaning you should hold the wheel perpendicular to the piece you’re cutting.

Keep the guard on no matter what you do. The guard may get in the way on some projects, but don’t take it off. It provides some protection from flying debris if the wheel or attachment shatters. It’s much better for the guard to take the hit then your torso or arms! [12] X Research source

Picking Angle Grinders and Accessories

Choose a 5-9 amp motor if you plan on using the grinder a while. If you want to use the grinder for a number of projects, try not to get the cheapest one. If you spend a little more, you can get a better quality machine. Pick a motor that pulls 5-9 amps, which will give you a little extra power and will likely stay in operation longer. [15] X Research source

  • That way, if you turn your grinder to max, you still won’t go over the max speed of the accessory.
  • A grinding disc with noise reduction and a handle that reduces vibrations can also make your grinder safer.

Community QA

Always wear eye protection and gloves, and point the grinder away from yourself; it might be a good idea to use it on a safe grinding area as well, along with clamps, vices, etc. Before grinding, examine the power cord, extension lead, plugs, sockets and power outlet for damage. Also, ensure that the grinding disc, guard, and attachments (including handle) are secure and correctly fitted. Lastly, inspect the grinding disc for damage; never use a damaged grinding disc, and never use a disc on a surface that might damage it.

Choosing the Best Angle Grinders—Buying Guide

Read on below to learn more about the different angle grinders and their best uses.

Types of Angle Grinders

There are four main types of angle grinders available, each with its own strengths, limitations, and type of power source. Most angle grinders can either be cordless, corded, gas-powered, or pneumatic.

Cordless Angle Grinders

Cordless power tools do not have the distance limitations of a power cord and allow operators the freedom of using them wherever they want, even outdoors. With battery technology improving every year, some cordless models are on-par, power-wise, with electric models. The only limitation of battery-powered grinders is if users don’t have a backup battery, then cordless grinders will generally only have a little over 45 minutes of run time.

Corded or Electric Angle Grinders

Corded models are one of the more popular types of angle grinders purchased for their power and unlimited power duration. A corded grinder is restrained by its cord, but for bigger jobs, a corded model doesn’t require batteries or the high maintenance needed for a pneumatic or gas power source angle grinder.

Pneumatic Angle Grinders

Pneumatic grinders work by using air pressure from an air compressor. When it comes to power levels, these would come just after gas-powered angle grinders and can be very expensive to own and operate, considering that air compressors have to be changed often because the refills are quite small and don’t hold that much air. One perk to a pneumatic version is that is tends to run longer than a cordless tool and is more powerful than a corded model.

Gas-Powered Angle Grinders

Like most gas-powered tools, gas angle grinders are the most powerful angle grinders available on the market. They are more expensive than other types of grinders and are also heavier. Additionally, gas-powered versions require a lot of maintenance and are not a top choice for smaller jobs.

We hope our review of the best angle grinders has been helpful, whether you were after something for heavy-duty projects or a model with the best safety features.
