Grinding Wheel vs Cut-off Wheel
                     What is the difference between a 
grinding wheel and a cut-off wheel?
Grinding wheels are thicker than a cut-off wheel. It is ideal to have 
a size 4-1/2″ x 1/8″ of the disc. Grinding discs with abrasive coatings are usually at 
least 1/4″ thick. The thin cutting discs cannot withstand considerable sideload without breaking, whereas the thicker discs may 
withstand significant force.
Cut-off Wheels vs. Grinding

The main differences between Cut Off discs vs Grinding discs 
aDreep:ending on the type of metal you’re cutting, the ideal choice of 
cutting wheels will be different. When compared to smaller, more 
flexible bits of metal, thick sheets of metal require more powerful 
cutting and grinding wheels.
Cut-off wheels are used for cutting on the 
peripheral surface. Why?
• Cut-off wheels are thin by design, and their affecting quality is 
unsuitable for side cutting.
• The fiberglass reinforcing adds strength to the wheel. It may be 
damaged if you use the side of the wheel. This weakens the 
wheel and puts it at risk of breaking.
