What is a bench Grinder?

A bench grinder is a type of power tool equipped with a spindle, grinding wheel and a powerful motor used for adding a smooth finish, grinding off rust or sharpening tools.

Bench grinder is a portable version of larger, industrial grade grinding machines found in many machinist and metal working shops. They spin at high speeds to remove material, which can be anything from wood to metal, by abrasion.

Since they are using abrasion, there is a lot of friction and they generally produce a lot of heat. Because of this, you may see operators using gloves when using one, especially if working with highly conductive metals.

Grinding tools usually measure between 6 and 8 inches in size and most recently, grinders come with dual grinding wheels with one made for coarse grinding and the other made for fine grinding.

What are the Advantages of owning a bench grinder?

If you do metal works or work in a metal workshop, you will realize that it is really important that you own a bench grinder for smoothing rough edges and imperfect welds.

Even those who don’t frequently work with metal can benefit from adding one of these tools to their garage or workshop, as these can be used for sharpening metal and renewing old, dull metal tools and keeping knives sharp, saving money in replacement costs.
