What thickness of grinding discs are made for cutting?

• A. 1/8 inch and under
• B. 1/4 inch
• C. 3/16 inch
• D. 1/2 inch

Answer: (A)

Cutting wheels are made very thin because a small, narrow contact area lets the disc slice through material with less resistance and less heat buildup. Thin discs—about 1/8 inch thick or thinner—produce a cleaner cut and stay cooler, which reduces warping and material damage. A thicker grinding disc would have to remove more material at once, generate more heat, and is more prone to binding, snagging, or breaking during cutting. That’s why the thickness used for cutting is 1/8 inch and under.
