Norton 66623334345 Deburring Disc 4 in Extra Coarse

Product Description

The NORTON 66623334345 is a rigid deburring disc designed for aggressive material removal on metal and fabricated workpieces. Built with a dual-abrasive construction of aluminum oxide and ceramic grain, this disc delivers fast cutting action at extra coarse grade. It measures 4 inches in diameter with a 0.5 inch thickness and mounts via a 1/4 inch arbor hole. Rated to a maximum of 8000 RPM, it handles high-speed angle grinder applications without flexing. Metalworkers, fabricators, and maintenance technicians use this disc for deburring, edge conditioning, and surface cleanup on steel and other hard metals.

This disc is suited for bench grinder and angle grinder setups in industrial, fabrication shop, and maintenance environments. The rigid construction and extra coarse grade make it effective for removing sharp burrs, flash, and weld splatter from cut or stamped metal parts. The arbor mount provides a secure, centered connection during operation. It is sold individually with a minimum order quantity of 25 units, making it appropriate for shop stock or production line use.
