Miniature Dremel-Compatible Rotary Tool Cutoff Wheels for Metal


	Side View

Use these wheels to cut through metal such as aluminum, iron, stainless steel, and steel. Choose coarser grit for fast cuts; choose finer grit for smooth cuts.

Warning: Use wheels that have a greater rpm rating than the no-load rpm of your tool.

Miniature Dremel-Compatible Rotary Tool Cutoff Wheels for Ceramics


	Side View

Made of diamond abrasive, these wheels cut ceramics, tile, and other abrasive materials. Because they’re miniature, they work best to make small, precise cuts. Use them to make plunge cuts in the center of material or to make flush cuts. The higher the grit number, the finer the grit. Choose a coarser grit for fast cuts; choose a finer grit for smooth cuts.

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.

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.
