Norton 66261009383 Deburring Disc 6 in Extra Coarse

Product Description

The NORTON 66261009383 is a rigid silicon carbide deburring disc designed for aggressive material removal on metals and other hard surfaces. At 6 inches in diameter with a 7/8-inch center arbor hole, this disc mounts directly to standard angle grinders and bench-mounted arbors. The extra coarse grade and density-7 construction deliver fast stock removal, edge cleanup, and deburring on ferrous and non-ferrous workpieces. Rated to 8,000 RPM, the disc maintains structural integrity under sustained load. At 1/2 inch thick and 0.42 pounds, it is built for repeated use in shop and field environments. Licensed metalworkers, fabricators, and maintenance mechanics are the primary users.

This deburring disc is suited for metal fabrication shops, maintenance and repair operations, and production environments where consistent edge finishing is required. The rigid construction handles flat surface work and edge deburring on cut pipe, plate, and structural steel. The arbor-mount configuration is compatible with standard 7/8-inch arbor grinders and related bench equipment. The extra coarse grade makes it appropriate for initial deburring passes rather than fine finishing work.

Key Features

• 6-inch diameter with 7/8-inch center hole for standard arbor mounting
• Silicon carbide abrasive for effective cutting on metals and hard materials
• Extra coarse grade and density 7 for aggressive stock removal and deburring
• Rigid construction maintains disc geometry under load
• 1/2-inch thickness provides durability across multiple uses
• 8,000 RPM maximum speed rating for safe operation on compatible equipment

Compatibility

Designed as a direct-mount deburring disc for angle grinders and bench arbors equipped with a 7/8-inch arbor. Confirm equipment RPM rating meets or exceeds 8,000 RPM before use.

Installation Notes

Installation and disc changes should be performed by qualified personnel following machine manufacturer guidelines. Always power down and unplug or lock out the grinder before mounting or removing the disc. Verify that the arbor size matches the 7/8-inch center hole and that the machine RPM does not exceed the 8,000 RPM disc rating. Wear appropriate PPE including face shield and gloves during operation.
