What does 27 cutoff wheel mean?

A Type 27 Cut Off Wheel is often referred to as a depressed center wheel. The mounting hardware is in the depressed center, allowing for flush cutting. 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.

How thick of metal can a cut-off wheel cut?

Resinoid-bonded abrasive cutting wheels are available in various sizes and thicknesses. The most popular range is 2 to 16 inches in diameter, and common thicknesses are from 0.045 in. to 1⁄8 in. Thinner wheels remove less material during the cut.

What does a cut-off wheel do?

Cutting wheels, or cut-off wheels, differ from grinding wheels in their function and structure. Where grinding wheels use an abrasive to grind large pieces of material off a workpiece from a shallow angle, cutting wheels typically make narrow, precise cuts at 90-degree angles.

What is a cut-off wheel used for?

In short, cut-off wheels are used to change the shape of metal. Either to cut it off, or to cut out portions of it. They are not made for fine work. They leave the surface rough and it will likely need to be deburred and smoothed before using the pieces for their final application.
