How to Choose – Buyer’s Guide

There are multiple options you must pay attention to before buying a bench grinder. Not all the products are quality on the market, but you should know what makes the best ones. Here are the things to consider.

  • Rotations per minute

It’s not the same if your grinder runs on 1750 RPM or 3500 RPM. The difference is huge. And it also depends on the type of tools you want to sharpen. Go for lower rotation for knives and more sensitive tools that need careful managing, or choose higher rotation rate for more industrial and more professional grinding needs.

  • Motor

There are motors with a very potent power of 5 amp that can deliver more rotation to the wheels. It is good to choose this kind of motors because these are usually induction motors with higher speeds. Therefore, it is good to choose higher amp values.

  • Overall construction

A base is very important in bench grinders. If the base is made of cast iron, it is a certain sign of good production. However, it’s not the only part of a bench grinder construction, because we have rubber feet for more stability, quality body for more effective grinding and side materials that make the grinder complete. If all of these construction parts are made up to quality standards, you should consider buying that grinder.

Types of Wheels

In this kind of industry, many abrasive wheels have different purposes, but most of them fit into few categories. First of all, the bench grinder wheels differ in size. Most bench grinders support 8-inch wheels, but there are also many units that support 6-inch options.

It usually depends on the size of the grinder and that is where the difference plays an important role. You must know which size is adequate for your grinder, in order to replace the wheels correctly.

What else is important to know?

The materials, of course. Most wheels are made of aluminum, which provides average abrasion potential, ideal for low-demanding applications, such as tool sharpening and material removing. In this case, we have abrasion that can shape the steel and similar materials. Usually, there are Universal, HSS and Carbide.

With the well-maintained wheels, these can provide long-lasting functionality and proper durability. Changing the overused wheels is always a good option if you want to get proper abrasion as the first day when you bought the grinder.

Bench Grinder Accessories

Some important bench grinder accessories include:

A wheel dresser is good for dressing the surface of the grinding wheel. It brings back the original wheel shape and exposes the fresh grains for renewed abrasion potential.

A bench grinder pedestal stand is very important if you want some additional stability of the grinder. You can easily reach it if you use a bench grinder with stand. It is enough to fix the stand to the table or other working surface and start grinding with improved stability.

Polishing pads are another kind of accessories for grinding wheels. You can use it in the same manner as a wheel dresses, but, in this case, the pads serve as a polishing and dirt removal tool. Another option might be a bench grinder buffer wheel that is used for additional polishing.

Parts of a Bench Grinder

Just like with any other machine, we have relevant parts of a bench grinder that make the unit running. Pay attention to these parts, as each of them serves the special purpose here.

  • Tool rest

In most grinders, tool rest is usually very tightly located within 2 to 3 mm of the wheel. It serves to prevent slipping down of the workpiece, which happens when the tool rest is not adequately installed. The workpieces can go down between the wheel and the tool rest while making a damage. Grinding is more effective when the tool is resting on a tool rest.

  • Eye shields

Eye shields are plastic bench grinder attachments above the grinding wheels. They are installed with the intention to protect the user from sparks and small particles that are products of grinding. Without eye shields, the usage of a grinding machine won’t be completely safe.

  • Wheels

As we mentioned before, the grinding wheels are the most important parts of a bench grinder. For successful grinding, the wheels must be properly maintained with accessories so the functionality can be better.

  • Coolant

During grinding, the tool reaches very high heat that can be reduced with a proper coolant. In most situations, we have small containers of water that serve as tool cooling. On the other hand, there are certain wet type grinder wheels where the bottom of the wheel operates within a pan of water, which is a good cooling method.

How to Use

 When you get the grinder for the first time, you may probably need to put all the parts together. It doesn’t come completely assembled, so you need to connect certain parts. Adjust the tool rest, install the bulb inside the lamp (if the grinder has the lamp) and adjust the speed you want to use.

After you turn it on, let the wheels rotate for at least one minute, so they can catch the standard operating circle. After that, you are ready for grinding. Make sure that you have a coolant by your side, which is helpful in the grinding process.

Take the tool you want to sharpen and place the middle of the tool on the tool rest. That’s when the grinding starts. The wheel of the grinder will rotate while you slightly move the tool from the middle to one end, and to another end afterwards.

Make sure that you don’t touch any part of the wheel and use the tool rest to align the tool correctly. Grinding can take from few seconds to few minutes, depending on how sharp you want your tool to be.

Care and Maintenance

 In order to prolong the life of your bench grinder, you should undertake certain maintenance steps. These will help you save a lot of time and money in the future.

  • Check the bolts regularly – This might not seem an important maintenance step, but it could bring a huge difference. You’ll have fewer worries about grinder functionality if you regularly check bolts and nuts. In the process of grinding, some nuts and bolts can loosen a little bit and you can see them falling out. In order to avoid that scenario, check if all the nuts and bolts are completely secured.
  • Inspect the tool rest – Sometimes, the tool rest is too close to the wheel and this could damage both the rest and the wheel. Check occasionally if space between is too narrow and adjust it to the safe distance.
  • Dress the tool regularly – Dressing of the grinder wheels will remove all the rough portions that gather over the time. A proper dressing will also smooth the wheel and prepare it for future operations. It is important to use a wheel dresser or a polishing pad for this purpose.

Size and Noise

 Size of a bench grinder depends on many factors. Therefore, you can find 19-inch grinders that are among the smallest on the market, but equally effective as 22-inch or 25-inch grinders with the similar functionality. The size does not determine the quality of the unit, but it can noticeably save your space in a garage or a workshop.

Noise is unavoidable as it is a part of the motor construction. In this case, we have noisy motors that run on more rotations, and, as a result, the noise is much higher. If the motor is designed well, we’ll have a smooth operation without any noisy distractions.

Safety Tips

  • Always turn off the grinder before taking any maintenance steps
  • Be careful during grinding not to touch the rotating wheel with fingers
  • Assemble the grinder parts as per instructions
  • Install eye shields properly so you can protect better
  • Check if the tool rest is at the proper distance from the wheel

Warranty

 The bench grinders can come with a limited 2-year warranty on most parts. Sometimes, you’ll find a 3-year warranty that offers many possibilities, like parts replacement and full customer service coverage. Go for the best package that covers as many options as possible.

FAQ

Where to find spare parts for my grinder?

You can check the official service from the manufacturer first. If there is one in your city, go and check if the spare part is covered with warranty paper. If you do not have official representatives in your surroundings, go for online options and check the availability of the spare parts for your bench grinder.

I am a first-time user. What should I know about the usage of the bench grinder?

First of all, familiar yourself with the manuals you get in the retail box. Learn how to properly install the important parts and how to start the operation. It is important to follow the necessary instructions in the manual you have.

Will my grinder work with a cable different from the original one?

In order to maintain the quality operation, it is recommended to use original cable that is made for your bench grinder. Other cables may cause complications and damages to the unit.
