Description

This low-speed grinder has been developed to help you to keep your tools sharp and ready to use. Most standard bench grinders run at more than 2800RPM, and with extra speed, comes extra heat. Heat build-up while grinding destroys the temper of your tool steel. The Carbatec Low-Speed Grinder runs at only 1450RPM, meaning less heat and less temper degradation (blueing). LOWER SPEED = MORE TORQUE!

The 2x large 8” (200mm) wheels offer minimal hollow grind and are both Aluminium Oxide made specifically for HSS and other tool steel. Standard ‘grey’ wheels are for general grinding, not sharpening. We supply 80G 120G wheels, so you can easily reshape and sharpen your tools, ready to use, without having to change wheels. We have done away with the small magnifier guards found on most grinders, in favour of large, clear guards, with sturdy steel wire supports. These will give you a more accurate visual reference, but also a longer life.

Flat robust tool rests are included, and with a host of accessories available, you can easily build a powerful sharpening station around this unit.

  • Low speed (1400 RPM vs 2800 RPM) is perfect for sharpening
  • Both wheels are Aluminium Oxide for High-Speed Steel
  • Metal (not plastic) spark guard supports for longevity
  • Clear spark guards for great visual referencing
  • Flat cast alloy tool rests for accuracy when sharpening
  • No Volt Release switch for your safe

Low speed bench grinder

The Rikon 80-805 Slow Speed Bench Grinder with 8″ wheel offers heavy duty grinding due to its 8″ diameter and 1″ width wheel. The Rikon 80-805 bench grinder is modeled with a smooth-start 1/2 HP motor operating at a no load speed of 1,750 RPM. The slow speed and large width make this grinder ideal for sharpening operations (among other uses). The combination of an 8-inch diameter wheel and slow grinding speed reduces heat build-up and minimizes the possibility of “bluing”, especially when you’re sharpening chisels and other tools.

The Rikon 80-805 Slow Speed Bench Grinder comes with two 1″ x 8″ white aluminum oxide grinding wheels. One wheel is 120-grit, and the other wheel is a much coarser 60-grit composition. It also comes with a diamond wheel dresser for use to true the grinding wheels before using or starting your next grinding operation. The Rikon slow speed bench grinder is equipped with a cast iron base that features anti-vibration rubber feet and mounting holes for convenient attachment to a workbench or grinder stand.

In addition, the Rikon 80-805 Slow Speed Bench Grinder features a polycarbonate eye shields that can be adjusted to stay put but can still be easily moved by hand. The 80-805 bench grinder comes with tool rests, eye shields, spark arrestors, a 6 ft. power cord, and 5-year warranty. Also available is the optional Rikon bench grinder stand 80-910.

Also, the bench grinder has sealed lubricated bearings in the motor housing that do not require any additional lubrication from the operator.

The 10 Best Bench Grinders of 2023

Michelle Ullman is a home decor expert and product reviewer for home and garden products. She has been writing about home decor for over 10 years for publications like BobVila.com and Better Homes Gardens, among others.

Johnathan C. Brewer II is a licensed general contractor specializing in kitchen, bath remodels, and general construction with two decades of professional experience.

Emily Estep is a plant biologist and journalist who has worked for a variety of online news and media outlets, writing about and editing topics including environmental science and houseplants.

If you work with metal, including auto repair, owning a bench grinder—which smooths and shapes rough edges, polishes and sharpens metal, and removes rust, paint, and other finishes—may be worth your while.

Deane Biermeier, a licensed carpenter and contractor, as well as a member of The Spruce’s Home Improvement Review Board, says, “Bench grinders are surprisingly versatile tools. Once you own one, you’ll wonder how you made it this far without it. However, most DIYers don’t need to spend a fortune on a bench grinder for it to be useful. Unless you depend on the tool to make a living, most homeowners won’t require one that’s larger than 1/2 to 3/4 horsepower. The secret that makes bench grinders so useful is the numerous and varied types of wheels and attachments available.”

We evaluated bench grinders based on power, versatility, reliability, construction quality, and overall performance.

Best Slow Speed

WEN 4286 8-Inch Slow Speed Bench Grinder

What to Look for in a Bench Grinder

Wheel Size

There are two common sizes of bench grinders: 6-inch and 8-inch. That number refers to the size of the grinding wheel. You’ll also find smaller bench grinders—3 inches is fairly common—that are used primarily for crafts or other detailed work.

For the average DIYer, a 6-inch bench grinder is the right choice. These tools typically spin the grinding wheels at a set speed of anywhere from 3,400 to 3,600 revolutions per minute, and they are excellent for sharpening knives and tools, grinding away rust, paint, or grime, sanding metal and wood, and other light-to-moderate repairs around the house or garage.

Eight-inch bench grinders are standard in automotive, woodworking, or metalworking shops, but some DIYers like them for home use, as well, particularly if they do a lot of work with metal. The wheels typically spin more slowly on these larger grinders—around 1,500 to 2,000 is a common range. Some have both a high and a low speed setting, so you can choose the one that best suits your needs—slower for more control, faster when you don’t need as much finesse.

Wheel Type

Most bench grinders come with two installed wheels, and usually, those wheels will have different grits and be different types. Commonly, one wheel will have a grit size between 80 and 120 for handling light grinding tasks, and the other will be either a medium grit of 30 to 60 or a coarse grit of 20 to 24 for more aggressive work.

The most common wheel materials are:

  • Silicon carbide: This common material is suitable for most grinding and sharpening tasks, but tends to heat up very quickly.
  • Aluminum oxide: Another common material that’s especially suited to sharpening and grinding hard metals. Aluminum oxide doesn’t heat up as quickly as silicon carbide.
  • Ceramic aluminum oxide: Excellent for a wide range of metals, ceramic aluminum oxide is long lasting, self-sharpening and not prone to overheating.
  • Wire: These wheels are covered in steel or brass wire filaments. They’re used mostly for automotive repairs and bodywork, but if you do a lot of work with metal, this might be a useful choice.
  • Buffing: These heavy cloth wheels are perfect for polishing, buffing, or shining up a wide variety of metals.

Power

You’ll find that some manufacturers state the power of their bench grinders in amps, while others use horsepower. As a general rule, 6-inch grinders have motors with around 2.1 amps of power—that’s around 1/4-horsepower. Most 8-inch grinders have around 5 amps of power, which is roughly 3/4 horsepower.

The most powerful bench grinders boast 1-horsepower motors, but these are generally used in industrial or professional settings, not for typical DIY projects.

While not a must-have tool for every DIYer, a bench grinder is more versatile than you might think. Along with its major use of grinding down metal, you can also use a bench grinder to sharpen tools, buff or polish metal, remove hardened dirt or other grunge from tools, cut metal or wood, remove rust, smooth and shape the edges of wood or metal, and even work on crafts such as jewelry-making, model-building, or reviving rusted metal items.

Just about every bench grinder has two wheels, which serves to increase the versatility of the tool. Typically, bench grinders come with one sanding/grinding wheel with a light-to-medium grit for light sanding tasks and one sanding/grinding wheel with a medium-to-coarse grit for tougher grinding situations. But there are many wheels available for these tools, some quite specialized. You can swap out one or both of the wheels for a finer or coarser grit, a wire wheel for shaping or cleaning metal, a buffing wheel for polishing, a cutting wheel for wood or metal, specialized wheels for grinding or cutting stone, or even a specialized wheel for cutting gemstones.

While grinding, shaping, and buffing metal are the primary uses of a bench grinder, you absolutely can use these tools on wood, as well. With the right wheel, your bench grinder can sand, cut, shape, buff, smooth, or polish a wide variety of woods. Typically, however, you won’t want to use a bench grinder for very soft woods; these tools are best used on hard materials.

Yes. Most bench grinders come with multiple wheels that correspond to different tasks. Take time to consider the task at hand, and select the correct wheel for the job.

A bench grinder is probably not a tool you’ll use every day. However, if it’s available and set up correctly, you’ll be surprised how often it comes in handy for everything from sharpening tools to rounding over thread ends on a cutoff bolt. We’ve assembled these tips to help you get the most out of your grinder.

Keep a Container of Water Handy

Most chisels and other cutting tools are made of tempered steel. If the steel gets too hot and turns bluish black, it’s overheated and won’t hold an edge very long. To avoid ruining the edge of a tool by overheating, keep water nearby to cool the tool. A good technique is to move the tool once across the bench grinder for no more than a few seconds. Then dip it in the water. If the steel edge does overheat and turns color, grind the edge back to good steel and start over.

Grind Small Objects Safely

Hold small objects with locking pliers. This keeps your fingers a safe distance from the grinding wheel and protects them against burns from the hot metal. It also gives you better control over the grinding process.

Make Tool Sharpening Guides

Here’s a better way to hold tools securely while you’re grinding them—and take the guesswork out of creating the right bevel angle. It’s a short piece of 2×4 with an angled end and a 1-1/4-in. hole for a clamp. I made one for sharpening chisels and plane blades, and a few more with different angles for wood-turning tools. Large labels with the tool’s name tell you which blocks are for which tools. For a Delta grinder with a 6-in.-diameter wheel, a 5-1/2-in.-long piece of 2×4 aligns the tool to the wheel just right. For other bench grinders, you may need to adjust this length. Note: The angle you cut on the block is not the same as the tool’s bevel angle. But let’s skip the math. To determine the block angle, turn off the grinder and hold the tool’s bevel flush against the wheel. The angle of the tool shaft to the workbench is the angle to cut on the 2×4.

Consider a Low-Speed Grinder for Sharpening

Unless they’re variable speed, most bench grinders run at about 3,450 rpm. If you’re careful and keep the wheel dressed (more on that in another tip), these high-speed grinders work fine. But for sharpening garden and other tools, a low-speed grinder running at 1,750 rpm is a better choice. The lower speed reduces the chance you’ll overheat the edge of your tool. Another advantage of a low-speed grinder (100 to 150) is that this type typically includes friable white grinder wheels, which do a better job of sharpening than the gray grinder wheels usually included with high-speed grinders. See how to use an angle grinder.

Dress Wheels Frequently

Wheel dressing squares the face of the wheel, but more important, it exposes new grit for more efficient cutting. As a wheel is used, the spaces between the cutting grit can become clogged, and the grit itself dulled. A wheel in this condition can cause overheating and slows material removal. A wheel dresser like the one shown here (15 to 30) has a bar with diamond grit impregnated in it. Holding the bar against the spinning wheel cuts away the surface to expose new grit, squares the face of the wheel and rounds the wheel. To use a dressing tool like this, start the bench grinder and wait for it to reach full speed. Then press the diamond wheel dresser against the spinning wheel, holding it perpendicular to the face of the wheel. Be sure to wear a good-quality dust mask. The fine aluminum oxide dust is very bad for your lungs. Draw a pencil line on the wheel before you start to help you gauge when you’ve removed enough material from the wheel. Dress the wheel just until the pencil line disappears.

Watch for the Sparks to Come Over the Top

When you’re sharpening a chisel or other tool, you can tell when the edge is getting sharp by watching the sparks. When the edge is blunt, the sparks are deflected downward. But as the edge gets sharper, the sparks roll over the tool and cascade down the surface facing you. When you see this start to happen, be careful about grinding much more because a thin edge is very vulnerable to overheating.

Make an Angle Gauge

Chisels and other cutting tools work best if their edges are ground at the correct angle. You can search online to find the optimal angle for whatever tool you’re sharpening. Most wood chisels should be ground to about a 25-degree angle with a secondary micro-bevel angle of 30 degrees on the tip of the blade. An angle gauge allows you to set the tool rest at the desired angle. You can make an angle gauge from a thin piece of cardboard using an inexpensive protractor. 1. MARK THE ANGLE ON CARDBOARD Align the center mark on the protractor with the top edge of the cardboard. Then turn the protractor until the desired angle is also aligned with the top edge. Draw a line along the protractor to mark the angle. Don’t forget to label the angle. Cut along the line to create the gauge. 2. ADJUST THE TOOL REST Set the cardboard on the tool rest and adjust the angle of the tool rest until the wheel contacts the center of the angled portion of the cardboard gauge.

Upgrade the Tool Rest

Inexpensive bench grinders have tool rests that are finicky and difficult to adjust. If you do a lot of tool sharpening or simply want a bench grinder tool rest that’s easier to adjust, consider adding a stand-alone tool rest. There are several variations, some made for specific tasks like sharpening lathe turning tools. This Veritas model has two adjustments for positioning and aligning the tool rest, and levers for easy tightening. You can also buy an attachment that holds chisels or plane irons.

Make Your Grinder Portable

Even the most nicely organized home workshops don’t have enough bench space to devote a section to a bench grinder. A good solution is to mount your grinder to a board or small stand so you can clamp it to the bench when you need it, and store on the shelf when you don’t. The compartment on this grinder stand is a good spot to keep your dressing tool and safety glasses so they’re handy when you need them. For a fancier version, build a little drawer to fit the space under the grinder. The stand is built from two 12 x 16-in. pieces of 3/4-in. plywood separated by two 4 x 12-in. uprights. We used two 5/16-in. bolts with washers and nuts to attach the grinder, leaving enough space in front of the grinder to mount a stand-alone tool rest.

Easy-to-Clamp Mobile Base

Shazam! Fasten your bench-top tools to your workbench in seconds. Bolt 3/4-in. plywood bases on the tools and then glue and screw a wood strip along the front edge to fit into a woodworking vise. Crank this strip into a vise to lock the tool into place. If you don’t have a vise, drill a couple of clearance holes along the face of the wood strip on the base and drive screws through the strip into the edge of your workbench. Then just unscrew to remove the tool.

Set Up a Polishing Station

A bench grinder fitted with a wire wheel on one side and a cotton buffing wheel on the other side, or buffing wheels on both sides, makes a great cleaning and polishing tool. You’ll also need a set of polishing compound sticks (14). Polishing compound sticks are color coded to indicate the grit, from coarse to very fine. To use the polishing wheel, hold the stick against the buffing wheel as it spins to transfer some polishing compound to the wheel. Then hold the object lightly against the wheel and let the compound polish the surface.

Sharpen Your Lawn Mower Blade

Sharpening your lawn mower blade is easy with a bench grinder. Grind the tapered cutting edges with a grinder only if you see nicks in the blade. Follow the factory angle of the cutting edge. The grinder will remove nicks in the blade much faster than you can file them.

Not All Grinding Wheels are the Same

You can use two kinds of aluminum-oxide wheels to sharpen your chisels; one is blue-gray and the other white. We used the darker-color wheel, which is harder and will keep its shape longer. The drawback, however, is that it grinds hotter than the softer, white wheel. Too much heat will weaken the steel. The soft wheel will need more frequent shaping with a dressing tool, but you’ll be less likely to burn the edge of your chisel while grinding. For best results, use a 100-grit wheel to shape your chisel blades.

Know When to Replace a Wheel

Slide the wheel over your finger and tap the wheel in four places with a screwdriver handle. All taps should sound the same. If they don’t, scrap the wheel. It’s cracked.
