Thin vs thick cut-off wheels

Thin wheels (1/32" to 3/64") cut faster with less heat, burr and discoloration, which matters on stainless and sheet metal. Thicker wheels (1/16" and up) last longer and stand up to side load on structural steel, rebar and chop saw work. Always match the wheel max RPM to your tool.

FAQ

What is the difference between a Type 1 and a Type 27 cut-off wheel?
A Type 1 wheel is flat and gives the straightest, deepest cut. A Type 27 wheel has a depressed center so the grinder nut sits below the face, which gives more clearance for flush cuts and light notching.

What size cut-off wheel fits my tool?
Match the wheel diameter and arbor to the tool and guard: 3 and 4 inch wheels with a 3/8 inch hole fit die grinders, 4-1/2 to 9 inch wheels with a 7/8 inch hole fit angle grinders, 12 to 16 inch wheels with a 1 inch or 20 mm arbor fit gas saws and chop saws.

Can I cut aluminum with a regular cut-off wheel?
Standard wheels load up on aluminum and other soft metals. Use a wheel made for aluminum, which uses a grain and bond that resists loading and keeps cutting cool.

How thin a cut-off wheel should I use on stainless?
A 3/64 inch (1.2 mm) or 1/32 inch (0.8 to 1 mm) wheel is typical for stainless sheet and tube. The thinner kerf reduces heat, so there is less heat tint and less risk of warping.
