Norton 66261006948 Hook Loop Disc Backing Pad 4.5 in

Product Description

The NORTON 66261006948 is a hook and loop disc backing pad designed to hold abrasive sanding discs securely during grinding and finishing work. With a 4.5-inch pad diameter and a 5/8-11 threaded mount, it attaches directly to standard angle grinders and disc grinders. The pad is rated for a maximum of 10000 RPM and features medium density construction, which balances conformability with firm disc support. It is sold individually and is a straightforward replacement or spare for shops and field technicians running hook and loop abrasive systems.

This backing pad suits metal fabrication, weld blending, surface prep, and general grinding tasks in both shop and jobsite environments. The hook and loop mount system allows fast disc changes without adhesives, making it practical for applications where operators swap grit frequently. It is commonly used by millwrights, pipefitters, ironworkers, and maintenance technicians who run angle grinders on steel, aluminum, and other hard surfaces. No vacuum holes are included, which is appropriate for dry grinding and finishing applications where dust extraction through the pad is not required.

Installation Notes

Installation is performed by threading the pad onto the grinder spindle by hand until fully seated — always ensure the grinder is unplugged or the battery is removed before mounting or removing the pad. Do not exceed the 10000 RPM maximum speed rating of the pad; verify the grinder speed matches or falls below this rating before operation. Inspect the pad for wear, delamination, or damage before each use and replace immediately if the hook and loop surface shows significant degradation. Follow applicable ANSI and OSHA abrasive wheel safety guidelines for mounting and guarding.
