What is a Type 1 cutting wheel?

A type 1 cut-off wheel, also known as a type 41 cut-off wheel, is completely flat. It is typically considered the most efficient type of wheel for general all-purpose cutting. Because it lacks a depressed center, it provides more cutting surface and minimizes interference with the workpiece.

What is the difference between Type 1 and Type 27 cutting wheels?

The Type 27 Cut Off Wheel must be used with an appropriate guard and a depressed center back flange. The center hub protects the user from cutting too deeply. The hub also allows for avoiding reinforcement wear and for extra rigidity for additional safety. The Type 27 produces 20% less cuts than the Type 1 on average.

What is a white grinding wheel used for?

White wheels are ideal for the general purpose grinding of ferrous metals but they are particularly suited for the sharpening of cutting tools such as chisels and plane irons. These wheels help keep your tools cooler to avoid overheating and weakening the cutting edge.

What is a Type 27 grinding wheel used for?

The Type 27 grinding wheels are a very popular group of general purpose and specialized abrasive tools intended for rough grinding on various materials. They are commonly used in building, shipbuilding, metal, foundry, engineering, chemical and other industries as well as in smaller workshops.
