Norton 63642585751 Quick-change Disc 4 in Silicon Carbide

Product Description

The NORTON 63642585751 is a 4-inch quick-change abrasive disc designed for rapid surface preparation and paint or coating removal. Built on a rigid nylon web backing with silicon carbide abrasive material, this non-woven disc operates at a maximum of 8,000 RPM and attaches via the Speed-Lok TR Type R system for fast, tool-free disc swaps. The extra coarse grade makes it well-suited for aggressive stripping tasks where speed of material removal is the priority. At 0.19 pounds, it is lightweight and balanced for extended use with compatible right-angle grinders and surface conditioning tools used by metal fabricators, maintenance technicians, and industrial tradespeople.

This disc fits into workflows where rapid coating removal, weld spatter cleanup, or surface blending is required. The Rapid Strip series is commonly applied on ferrous and non-ferrous metals in fabrication shops, field maintenance, and industrial service environments. The Type R attachment system is compatible with standard quick-change disc pads available from multiple tool manufacturers, making it easy to integrate into existing grinder setups without additional hardware.

Installation Notes

Installation of quick-change abrasive discs should be performed by trained technicians familiar with angle grinder safety practices. Ensure the grinder is disconnected from its power source or air supply before mounting or removing any disc. Verify the tool's rated RPM meets or exceeds the disc's 8,000 RPM maximum before operation. Always confirm the Type R backing pad is in good condition and fully seated before running the disc at speed.
