Multipurpose Portable Cutoff Saw Wheels
 | |
Side View |
Make burr-free cuts in a variety of materials—from rubber to metal to stone. Made from a blend of silicon carbide and aluminum oxide abrasives, these cutoff wheels won’t clog or burn when slicing through nonmetals. They’re often used to cut hard or thick pipe, sheets, and bars to size.
Warning: Use wheels that have a greater rpm rating than the no-load rpm of your tool.

Miniature Long-Life Grinding Bits for Nonmetals
 |  |  |  |  |
Style 1 | Style 2 | Style 3 | Style 4 | Style 5 |
Made with diamond abrasive, these bits are extremely hard and last longer than tungsten carbide. They have a small shank and head for precise and intricate jobs. To extend the life of these bits and improve their finish, use a water- or oil-soluble mist or coolant. They are also known as mounted points and die grinder bits. Head diameter is measured at the widest point.
Caution: As bit shank is exposed beyond 1/2", maximum safe rpm decreases significantly. Refer to ANSI standard B7.1. Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.
