    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.

    Rotary Tool Arbors

    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 Abrasive—Boron nitride abrasive 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.
