Norton 63642504873 Disc Backing Pad Quick-change Type S

Product Description

The NORTON 63642504873 is a Quick-Change Type S disc backing pad designed to mount abrasive discs on angle grinders and right-angle tools used in metalworking, fabrication, and surface preparation applications. The pad accepts a standard 5/8-11 threaded spindle and is rated for a maximum operating speed of 8,600 RPM. Its hard density construction provides firm, stable backing that supports consistent stock removal and controlled grinding across flat and moderately contoured work surfaces. This type of backing pad is a standard consumable accessory handled by metal fabricators, welders, pipefitters, and maintenance technicians working with angle grinders.

This backing pad is suited for use in industrial, commercial, and trade shop environments where quick-change disc systems are preferred for faster disc swaps and reduced downtime. The Speed-Lok quick-change compatibility allows the operator to swap abrasive discs without removing the pad from the grinder spindle. Typical applications include weld blending, scale removal, and surface conditioning on steel, iron, and similar ferrous materials. The hard density backing is well matched to aggressive grinding tasks that demand rigid disc support.

Compatibility

Designed for use with Speed-Lok quick-change abrasive discs on angle grinders and right-angle tools equipped with a 5/8-11 threaded spindle. Confirm disc size and quick-change type compatibility before use.

Installation Notes

Installation is performed by metal fabricators or maintenance technicians familiar with angle grinder tooling. Power down and disconnect the grinder from its power source before threading the backing pad onto the spindle. Thread the pad onto the 5/8-11 spindle by hand and secure it per the tool manufacturer's instructions. Do not exceed the 8,600 RPM maximum speed rating, and always verify that the abrasive disc speed rating meets or exceeds the tool's no-load RPM before operation.
