Walter 07Q049 Disc Backing Pad 4-1/2 in Hook Loop

Product Description

The WALTER SURFACE TECHNOLOGIES 07Q049 is a rigid disc backing pad designed for use with 4-1/2 inch hook and loop abrasive discs on angle grinders and surface preparation tools. Built from plastic with a 5/8-11 threaded mount, it accepts standard grinder spindles and holds discs securely via a hook and loop interface. The pad is rated to a maximum of 11,000 RPM and includes a centering pin to aid disc alignment during installation. It is a non-flexible (rigid) pad, making it suited for flat surface grinding and blending applications where consistent backing support is required.

This backing pad is intended for use with 4-1/2 inch Quick-Step discs in metal fabrication, weld blending, and surface conditioning work. It is commonly installed by metalworkers, welders, and maintenance technicians working on structural steel, fabricated components, or industrial equipment. The hook and loop mount allows for fast disc changes without tools, reducing downtime on the job.
