Thing to Consider Before Buy

Size

You will see bench grinders in various sizes. A lot depends on the spaciousness of your work area when choosing the right grinder size. 

For owners of smaller shops, you will be better suited to bench grinders with ½ or ¼ horsepower. For this category of grinders, cutting wheels of 1 – ½ inch will get the job done.  

If you have a bigger task on hand, go for bench grinders with bigger wheels, even running up to 8 inches. This increases the surface area for quicker grinding. Of course, such bigger wheels work with bigger motors. 

Power & Speed

The power of bench grinder is reflected in the revolutions per minute (RPM) of the grinding wheels. It is all simple. Bench grinders with faster speed and power get your job done quicker.  

Faster speeds are great when you have hard metals to work on. You definitely will not need as much speed when you work on thick steel as when you work on wood. Typically, many bench grinders have their speeds ranging from 3600 rpm to 3000 rpm. 

Grinding Wheel type

When buying bench grinders, you have to pay particular attention to the type of grinding wheel it has. First, you have to consider the kind of material you would be grinding. 

If you would be grinding cast iron, you should be considering silicon carbide abrasive wheels. On the other hand, when you have to grind steel materials, use aluminum oxide wheels.  

The convention is to work softer materials with wheels of harder grades having coarse grit while brittle (and tough) materials are best worked with wheels of softer grades having finer grit.  

The following are the prominent types of grinding wheel you see with bench grinders. 

  • Cylinder wheel: Just as the name suggests, this wheel is hollow and notably large. They find valuable use in producing flat surfaces.  

Cylindrical wheels are best used with vertical and horizontal bench grinders. They are wide too, even boasting as much as a width of 12 inches. 

  • Straight wheel: Straight wheels so to say are the most prominent wheel types. They are very handy when it comes to surface grinding. Hence straight wheels are commonly deployed in sharpening cutting tools like chisels. 
  • Tapered wheel: These wheels are best suitable for grinding gear teeth. Tapered wheels are used in significantly delicate works. This application is unsurprising, given that towards the edge, this wheel tapers off.   

There are other specialty wheel types that are not as commonly deployed as these grinding wheels we have just mentioned. This rarer class of wheels includes diamond wheels, saucer wheels, and cut-off wheels. 

8 inch or 6 inch

Aside from the type of grinding wheel, you must also be keen on its size. Your choice of the wheel size depends on the intended purpose of the wheel. 

Usually, we have wheels or 6 inches, running up to 8 inches. This range will sufficiently take care of the majority of your jobs you will come across. 

For home use as is typical of most DIY (Do It Yourself) jobs, you would be fine with a grinding wheel of 6 inches. The majority of this size of wheels run in the region of 4 amps. Their power capacity best suits your home improvement projects. 

Thus, most 6-inch grinding machines have a speed range of 3400 to 3600 rpm. They could be heavy. But they are notably quiet. 

If you are looking at an industrial project, you should be considering the 8-inch grinding wheel. This works well with wire brushes and buffing wheels. 8-inch wheels don’t need significant wheel changes, although they are sort of slower.

Anti-Vibration Features

You would be in for a hellish experience if your bench grinder vibrates too much. This is because of the constant disruptions would make it hard for your job or hands to stay in place. Undoubtedly, this can be as exhausting as annoying!

Go for bench grinders with suitable anti-vibration features that enhance the stability of the grinder while in operation. This is why most premium quality bench grinders are made with solid cast iron. Such facility reduces the vibration to a reasonable degree.

Spark Protection

Flying sparks are quite normal when you work with bench grinders, but how good is the spark protection? Your choice of bench grinder should be amply supplied with spark deflectors.

These spark deflectors usually cover as much as 75% of the wheel. This leaves the remaining 25% — typically situated at the front – for you to work on. 

The job of these spark deflectors, as you would guess, is to keep the sparks from flying right at you. That would be damn catastrophic. 

With these deflectors covering a huge part of the wheels, the sparks (or fragment of the material you are working on) are localized so they don’t jump right at you or all your workshop. 

The spark deflectors are also valuable in keeping off stuff from falling directly on our wheels and sparking all over. Such accidental falls are not uncommon given that you can mistakenly knock something on the grinding wheel, or the inherent vibration of the grinder could cause other stuff to fall on the wheel.

Built-in light

When working on your bench grinder, you need adequate visibility. You not only need to correctly see what you are working on to do a great job, but you also need to see well to keep your hands safe. 

It would be fantastic if your bench grinder comes with in-built light in the form of LED lamps to light up your work area sufficiently.
