Dremel Quick-Change Rotary Tool Cutoff Wheels


	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.

Diamond Abrasive—Diamond abrasive wheels are the most durable and last the longest while producing smooth and precise cuts. They are ideal for cutting hard and abrasive materials such as marble, concrete, brick, porcelain, ceramics, hard epoxy, and soft or hardwood.
