Norton 63642585704 Deburring Disc 8 in Extra Coarse

Product Description

The NORTON 63642585704 is a rigid silicon carbide deburring disc designed for aggressive material removal on metal, composites, and similar hard surfaces. At 8 inches in diameter and 1/2 inch thick, the disc mounts via a standard arbor connection using a 1/2-inch center hole. Rated to 6000 RPM maximum, it handles bench grinder and pedestal grinder applications where consistent, extra-coarse stock removal is required. The silicon carbide abrasive delivers sharp, fast-cutting action suited to deburring, edge conditioning, and surface prep work. Machinists, fabricators, and tool room technicians are the primary installers and operators of this disc.

This disc is suited to deburring and edge-breaking operations on metal parts, castings, and fabricated components in both shop and light industrial environments. Its rigid construction resists flex during contact, making it appropriate for flat-face grinding and controlled material removal rather than contouring work. The extra-coarse grade accelerates cycle time on heavily burred or rough-cut workpieces. The disc ships individually and is sold in minimum quantities of 5 units per order.

Key Features

• 8-inch diameter rigid disc for use on bench or pedestal grinders
• Silicon carbide abrasive in extra-coarse grade for fast, aggressive stock removal
• 1/2-inch arbor hole for standard grinder spindle mounting
• 6000 RPM maximum rating for safe high-speed operation
• 1/2-inch disc thickness with density rating of 7 for consistent face contact
• Rigid construction maintains flat profile during deburring and edge-conditioning passes

Compatibility

Designed for use on bench grinders and pedestal grinders accepting an 8-inch diameter rigid abrasive disc with a 1/2-inch arbor center hole and a maximum spindle speed at or below 6000 RPM.

Installation Notes

Installation should be performed by a qualified machinist or grinding equipment operator following the grinder manufacturer's mounting instructions. Always disconnect and lock out power to the grinder before mounting or removing the disc. Verify that the machine's rated spindle speed does not exceed the 6000 RPM maximum marked on the disc before operating. Inspect the disc for cracks or damage prior to each use and do not exceed the rated speed under any circumstances.
