4-1/2" Type 27 Ceramic Depressed Center Wheels, 5/8"-11 Arbor, 0.045"-Thick, 13, 300 RPM

This 3M™ Cubitron™ II Cut-Off Wheel features precision-shaped ceramic grain to help in providing exceptionally fast cutting and long life. The triangular abrasive grains form sharp peaks that slice cleanly through metal, rather than gouging or plowing as traditional abrasives do. The peaks also sharpen themselves continuously as the points break off, which helps to provide a cut with reduced friction-related stress cracks and discoloration. Use for perpendicular cuts on metal such as auto body or marine sheet metal, stainless steel tubing, exhaust pipes, clamps, rusted fasteners, mild steel, and aerospace alloys. A wheel guard that fits the size of the cut-off wheel (available separately) is required for use.
