Considerations when Choosing a Bench Grinder 

When choosing the best bench grinder, you must make a few considerations before simply purchasing the first machine you see. Here are a few things that you should look out for to ensure you get the perfect bench grinder for you.

Power

The power of most bench grinders will be found in amps, with some manufacturers choosing to use horsepower.

The general rule is that 6-inch grinders will have an amperage of around 2.1. The majority of 8-inch grinders have more significant power at about 5 amps, equating to around ¾ of horsepower.

If you’re looking for more power, 1 horsepower grinders are available, but they are usually for more professional or industrial settings than DIY purposes.

Wheel Size

When it comes to wheel size, bench grinders usually have either a 6-inch or 8-inch wheel. Some grinders include 3-inch wheels, but these are generally designed for arts and crafts rather than DIY applications.

For the average DIY job, a 6-inch grinder is more than enough, and they are usually a little cheaper than the larger versions. These grinders come at a range of different speeds, usually between 3,400 to 3,600 RPM.

They are a perfect choice if you are looking to sharpen existing tools, grind away rust, paint, grime, sand, wood and metal, and any other lighter jobs that don’t need too much power.

In the world of woodwork, metalwork, and even the automotive business, eight-inch bench grinders are the most commonly seen. Still, they also have a place for DIYers at home, especially good work with metal applications.

The larger wheeled bench grinders usually have a spin at a slower rate between 1,500 and 2,000 RPM.

You may find that these larger bench grinders offer a variable speed switch allowing you to select the perfect speed for the specific job you’re working on. 

Wheel Type

Bench grinders commonly consist of two grinding wheels, each with a different level of grit more suited for various tasks. One wheel usually has a grit size between 80 and 120, great for lighter work.

Medium grit is generally between 30 and 60, while a more aggressive coarse grit between 20 and 24 is better for more heavy-duty work.

The materials used for the wheels can vary, with the most common choices being:

  • Silicon carbide: While this commonly used material is helpful for most grinding and sharpening projects, it has a tendency to heat up very quickly.
  • Buffing: Made of heavy cloth, these durable wheels can be used to clean or polish metals of all kinds.
  • Aluminium oxide: Hard metals are often sharpened and ground using this material. Silicon carbide heats up much faster than aluminium oxide.
  • Wire: In the case of these wheels, brass or steel wire filaments cover the surface. You should consider this if you are working with metal a lot. Most people use them for automotive repair.
  • Ceramic aluminum oxide: In addition to being long-lasting, self-sharpening, and not prone to overheating, ceramic aluminum oxide is excellent for a wide range of metals.

To Sum Up

There are a number of different bench grinders, no matter what your budget or skill level is.

Be sure to do your research and you’ll have a great bench grinder on hand, whether it’s sharpening your tools or rounding thread ends on a cutoff bolt.
