If you are a first-time buyer then you may want to find a grinder that does not break the bank, gives you great quality and durability, gives you the most for your money, and adds extra features for no extra cost.

The only question that remains is, why would one need a bench grinder? Grinders are great because they will smooth the rough cutting edge on a wide range of cutting tools. They can be used for cleaning up imperfections on metal projects and can grind rivets off.

Types of Bench Grinders

Types of Bench GrindersBench grinders are very simple yet versatile machines with many designs and manufacturers. Similarly, many types of wheels can be outfitted on the bench grinders for various tools.

Use a rough stone wheel for repair work, such as smoothing out the roughened edges of a worn old screwdriver, or use a fine stone to flatten out a chisel. For cleaning rust off of tools before sharpening, or even old door hinges for reuse, use a wire wheel.

The rough, sharp wires tear rust chips off with ease. If you simply want to polish an item, use a buffing wheel. A buffing wheel is a simple cloth wheel, which should be coupled with a buffing compound (rogue) before polishing.

In addition to the various wheel types, the grinders themselves come in different makes and models. The size of the grinders (like a 6 or 8-inch bench grinder) is determined by the diameter of the wheels attached to the machine.

  • The Baldor 600E is considered the best bench grinder by many bench grinder reviews. This American-made industrial grinder runs without vibration and is extremely powerful for a grinder of its size. Baldor is notable for their 10-inch bench grinders and even 12-inch bench grinders, providing the heaviest of heavy-duty industrial machines. Grinders of this size are best used for large projects the smaller grinders can’t handle.
  • The Central Machinery 37822 is a small, light-duty grinder, complete with a gooseneck lamp and easily removable/attachable wheel covers. While it can’t handle heavy-duty jobs, this quick little bench grinder can sort out small jobs quickly and efficiently.
  • The Crafstman 21154 has fairly large tool rests, a speed control dial, a large quench tray, and a large gooseneck work light. Highly rated and fairly cheap, this bench grinder is a popular favorite in the workplace. This variable speed grinder gives it a unique function in its ability to perform a variety of jobs.
  • The DeWalt DW756 is a 6-inch bench grinder that covers nearly every basic job perfectly. The only recurring complaint is that the screws keeping the wheel covers in place are extremely tight, so pack a handy screwdriver if you need to change them out. If you need to upgrade to an 8-inch bench grinder, try the DeWalt DW758 instead.

Variable Speed Bench Grinders

Variable Speed Bench Grinders

Craftsman 9-21162 8 inch

Variable speed bench grinders are in the “above average” category for buyers. As the name suggests, it is capable of changing its rpm. There are two immediate benefits of buying a variable speed grinder. The first is that you can slow down the tool for better sharpening.

This allows you to keep your tools in the best working condition. The second benefit is being able to speed the tool up. This provides better cleaning, buffing, and polishing. One model to look at is the Delta 23-196 6 inch variable speed bench grinder. It comes at an affordable price, varies speed by an upfront speed dial that goes between 2, 000 and 3, 400 rpm, has a movable work light, and tool rests.

If you are looking for better quality the Craftsman 9-21162 8 inch variable speed model is perfect. This brand is top notch and comes with all the previous features. It does go up to 3, 450 rpm instead, and will last longer than other leading brands. When deciding on whether to buy a variable speed vs a normal bench grinder think if you will need both sharpening and cleaning/polishing. If you said yes, then a variable speed bench grinder is for you.

Low-Speed Bench Grinders

Low Speed Bench GrindersWhy low-speed bench grinders? Great question. When a grinder spins at the same rpm, its wheels generate a high surface speed. This is good because the wheel removes metal quickly, but the product of this is increased heat. This excessive heat can ruin the temper and hardness of a cutting edge.

This is very bad, but luckily we have low-speed grinders to help us with this dilemma. A great slow speed grinder is the WEN 4286 8 inch model. It has eye shields, tool rest is covered with a two-year warranty, and is available at a decent price. Another model is the RIKON 80-805 8 inch slow speed bench grinder.

It is ideal for sharpening operations because it reduces heat build-up. This model runs at a higher price but includes movable eye shields, rubber feet for vibration reduction, and everything the WEN model has besides the 2 year warranty.

Industrial Bench Grinders

Bench Grinder Accessories and Attachments

Bench Grinder Accessories and AttachmentsIt is important to look for any necessary accessories or attachments after the consumer has bought their machine. It is a good idea to try and get a grinder that already comes with the accessories, but if your machine did not come with any do not worry. Accessories are affordable and beneficial to the consumer.

One accessory/attachment that is fairly important is the eye shield. Most grinders already come equipped with these, but if yours did not or has broken then it is important to go buy one. These eye shields protect the user’s eyes while grinding. A standard eye shield example would be the 286439-00 eye shield model.

This is specific to the DeWALT DW765 model but gives you the idea of what an eye shield costs and looks like. This accessory may seem expensive for its size but is understandable when most eye shields last for years. Another accessory that will be extremely useful is the grinding wheel dresser.

Bench Grinder Accessories and AttachmentsThe purpose of this accessory is to dress the surface of the grinding wheel. This simply means that the dresser will help return the wheel to how it was originally. It also will help remove any abrasive fragments caught in the wheel. An affordable model that gets the job done is the Forney 72390 dresser.

This model is 10 ½ inches long, so you can keep a good grip while in use, has heat treated carbon steel cutters, and is great at re-truing and cleaning the surface of your wheel. Note, the cutters do wear out eventually, but instead of going and buying a new dresser you can go purchase the cutters separately.

This tool is also one the accessories that would be highly recommended in order to get the most out of your machine. There are still other bench grinder parts that are available to consumers, and tons of replacement parts, such as the bench grinder wire wheel or even some tool rests. Overall, you should take the time to look at useful accessories/attachments and decide on which ones will help your machine work better, last longer, and improve safety.

Bench Grinder Tool Rest

Bench Grinder Tool RestTool rest are exactly what they sound like. A resting place to lay the tool as the user grinds, buffers, polishes, etc. It is supposed to be solid, square, and adjustable so that the user can grind at different angles when needed. The major issues with tool rests are that they are usually never solid and square.

This creates a lack of stability and can lead to problems when grinding your tools. The Robert Larson grinder tool rest is great if you are looking for a better tool rest for your machine. This tool mounts directly to the bench on a 6 or 8-inch grinder and is easily folded out of the way.

This tool rest is perfectly suited for Veritas grinding jig and skew grinding jig as well. Your best bet, though, is to find a bench grinder that already comes equipped with a decent tool rests. The Rockwell Shop Series RK7867 6 inch bench grinder has exactly this.

Not only will this model leave green in your pocket, but it also comes with a perfect adjustable tool rest for precision control. Based on your needs you should be able to determine if you should buy an attachment tool rests or a new machine already equipped with one.

Bench Grinder Stands

Bench Grinder StandsBench grinder stands are a useful accessory to your bench grinder. They make your grinding and sharpening jobs easier. Once your grinder is bolted down to the stand, the stand becomes a stable and dependable workstation where you can sharpen your tools, blades, level surfaces, and smooth edges.

A simple model would be the Pit Bull CHIG 1750 bench grinder stand. It comes with two pre-drilled holes to allow easy attachment for your grinder. It features four legs instead of the common 3. This helps with securing stability and gets rid of any extra wobble. It also includes a 1-5/16” by 1/2” by 13-3/8” tool tray.

Another model would be the Craftsman 9-19210 stand. It comes with a cast iron top and has dimensional holes to fit most grinders/buffers. This stand bolts to the floor giving a peak in your stability, but taking away from the maneuverability of the stand.

This stand includes a water tray/water pot for cooling hot objects (great feature in case your grinder did not come equipped with one) and is a good buy for anyone who is not shopping on a small budget.

Bench Grinder Safety and Maintenance

You’ll want to make sure you always handle and store your grinding wheels in a careful manner. Most of the wheels are vitrified/glass bonded products and are very strong, but brittle. Before you begin using your grinder, perform a visual test to check the wheels for any cracks or damage.

Bench Grinder Safety and Maintenance

After your visual inspection is complete, you should “Ring Test” all wheels before mounting them to the grinder. If a wheel has any damage or disintegration problems, it can fire off solid fragments at speeds of over 125 miles per hour when used.

To perform the “Ring Test,” simply tap the wheel gently with a nonmetallic object (such as the handle of a screwdriver or a wooden mallet, depending on the wheel weight). Tap the wheels at about 45 degrees on each side of the vertical centerline, and about 1 or 2 inches from the outer edge of the wheel.

After completing this, rotate the wheel 45 degrees and repeat. An undamaged wheel will give off a clear, metallic tone. A cracked wheel will give off a hollow, almost dead sound. If that’s what you hear, do NOT use the wheel! Once you have mounted the wheels, let them run at operating speed for about one minute before grinding.

This is where the wheel will most likely break if damaged, so do NOT stand in front of or in line with the wheels during this test.

Make sure your bench grinder is permanently mounted. It should NOT move or fall over during use, as this could prove dangerous or even fatal.

Always check your machine’s speed against the safe operating speed marked on the wheel. Inspect your mounting blotters and flanges as supplied by the wheel manufacturer.

Always keep your work area clean and free of anything that could accidentally hit the grinding wheel during use.

Be sure you wear proper personal protection at all times. These include eye and face protection, apron, gloves, safety shoes, and similar items. Maintain your tools as if your life depends on it. When grinding, grind on the wheel’s face (outer diameter) only.

Do NOT side grind. Keep your grinding wheel face open and free from metal build-up. Outfit your wheel to remove foreign metals and open the wheel face with new, sharp, abrasive grains.

Tips on Choosing the Best Bench Grinder

Tips on Choosing the Best Bench Grinder

Tip #1: Identify Your Needs

You need to decide on what your needs are BEFORE going out and looking for a bench grinder. This is important because you need to get a machine that works best for your needs. You could encounter an issue if you don’t follow this tip. A great example would be a guy needing a grinder only to sharpen his tools.

He should not go out and purchase a 3, 600 rpm machine because slower speeds are better for sharpening. Instead, he wants to buy a slow speed grinder. Likewise, you should get a machine that has higher rpm (3, 600+) if you are needing to buff objects. If you are looking for both sharpening and buffing then a variable speed machine is the best choice for you.

Tip #2: Decide On Your Price Range
