Norton 63642543225 Disc Backing Pad Quick-change Type S

Product Description

The NORTON 63642543225 is a Quick-Change Type S disc backing pad designed to hold abrasive discs during grinding, blending, and finishing operations. It accepts a 0.25 inch shank and is rated to a maximum of 20,000 RPM, making it suitable for use with standard die grinders and right-angle tools. The medium-density pad construction balances disc conformability with support, which helps maintain consistent contact across the work surface. Speed-Lok TS quick-change compatibility allows for fast disc swaps without additional tools. This part is used by metal fabricators, pipefitters, and general tradespeople working with angle grinders or die grinders on surface prep tasks.

This backing pad is suited for light industrial and trade applications where quick disc changes are required. The Speed-Lok TS interface is commonly found in metalworking, HVAC duct work, pipe fabrication, and structural steel finishing. The 0.25 inch shank fits standard collets on die grinders used across mechanical and fabrication trades. Medium density provides adequate backing for general-purpose flap discs, surface conditioning discs, and coated abrasive quick-change discs designed for the Speed-Lok TS system.

Installation Notes

Installation and disc changes should be performed by a qualified tradesperson with the grinder fully powered off and disconnected from its air or electrical supply.

Inspect the pad for wear or damage before each use and replace if the pad surface shows cracking, separation, or uneven wear.
