Norton 66261099378 Deburring Disc 6in Extra Coarse

Product Description

The NORTON 66261099378 is a rigid deburring disc engineered for aggressive material removal on metal workpieces. It measures 6 inches in diameter with a 1/2-inch center hole and 1/2-inch thickness, and it is rated for a maximum speed of 8000 RPM. The abrasive blend combines aluminum oxide and ceramic grain at an extra coarse grade, delivering fast cutting action on burrs, sharp edges, and surface scale. The arbor connector provides a secure, centered mount on compatible angle grinders and disc grinders. Machinists, fabricators, and metalworking professionals use this disc for deburring, edge conditioning, and surface prep on ferrous and non-ferrous metals.

This disc is suited for heavy-duty deburring tasks in fabrication shops, manufacturing facilities, and maintenance environments. Its rigid construction holds the abrasive face flat against the workpiece, which is important when working on flat stock, plate, and structural profiles. The extra coarse grade makes it most effective where material removal speed matters more than finish quality, such as removing weld spatter, flash, and heavy casting burrs. It ships individually with a minimum order quantity of 25 units.

Installation Notes

Installation should be performed by qualified personnel following the grinder manufacturer guidelines and applicable ANSI B7 safety standards for abrasive wheels. Always power down and disconnect the grinder before mounting or removing the disc. Confirm the grinder spindle speed does not exceed the 8000 RPM maximum rating marked on the disc before operation. Inspect the disc for cracks or damage before each use and never use a disc that shows signs of damage.
