Toolroom Grinding Wheels for Hardened Steel
Made with boron nitride, second in hardness to diamond, these wheels are highly wear resistant and easily cut difficult-to-grind steel parts. While they’re not as hard as diamond, they dissipate heat better.
Caution: Use only accessories that have a greater rpm rating than the maximum speed of the grinder you choose.

Long-Life Grinding Bits for Metals
Similar to diamond, boron nitride is harder than aluminum oxide and lasts longer. Bits are also known as jig grinding pins and mandrels.
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.

Dremel Quick-Change Wheels
Swap accessories quickly and safely without tools. These wheels have a special arbor hole that work with a pull-twist-release locking mechanism (sold separately). They are also compatible with standard Dremel wheel arbors with a slotted-head-screw locking mechanism.
Boron nitride wheels remain sharp longer, stay cool, and won’t shrink. They are good for cutting nails, rebar, metal studs, threaded rod, conduit, metal HVAC duct, metal door jambs, and galvanized struts. These wheels last 20 times longer than aluminum oxide cutting wheels.

Bench and Surface Grinder Cutoff Wheels for Hard Metal
Made with boron nitride, second only in hardness to diamond, these wheels are highly wear resistant, so they easily cut steel with a Rockwell hardness of C50 or greater, including alloy steel, A2, D2, and T15 tool steel. While these wheels are not as hard as wheels made with diamond, they dissipate heat better.
Warning: Use wheels that have a greater rpm rating than the no-load rpm of your tool.
