Shaped Norton Toolroom Grinding Wheels for Metals


Flared-Cup Grinding Wheel

The special shapes of these wheels provide more clearance than typical straight wheels.

Caution: Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.

Norton 5SG Abrasive—5SG blue wheels are for heavy material removal. They are ceramic aluminum oxide, which lasts up to five times as long as 32A wheels.

Grinding Bits for Nonmetals


Style 1	Style 2	Style 3	Style 4	Style 5	Style 6	Style 7	Style 8

Almost as hard as diamond, these tungsten carbide bits cut through nonmetals without generating heat.

Bits 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.

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.
