Norton 66252842178 Type 27 Grinding Wheel 3x1/4x3/8

Product Description

The NORTON 66252842178 is a Type 27 depressed center grinding wheel built for metal grinding applications. Part of the NorZon Plus line, this wheel measures 3 inches in diameter with a 1/4 inch thickness and a 3/8 inch arbor bore. It carries a maximum operating speed of 18000 RPM. The depressed center Type 27 profile allows the wheel to sit at an angle to the workpiece, giving the operator better clearance and control during aggressive material removal. Fabricators, welders, pipefitters, and metal trades professionals use this wheel for grinding welds, deburring, and surface prep on ferrous metals.

This grinding wheel is suited for use on angle grinders in metal fabrication shops, welding operations, structural steel work, and pipe fitting applications. The NorZon Plus abrasive formulation is engineered for metal grinding where consistent cut rate and wheel life are priorities. Sold in a case quantity of 25, it is appropriate for shops and contractors that consume abrasive wheels at a regular pace and want to maintain stock on hand.
