3M 7100003161 Roloc Disc Pad 1 Inch Medium Grit

Product Description

The 3M 7100003161 is a Roloc disc pad designed for use with 1-inch quick-change abrasive discs. It features a 1/4-20 internal thread mounting interface that locks discs securely onto compatible right-angle grinders and die grinders. The pad accepts medium-grit Roloc discs and is sold in cases of 5 units. This type of backup pad is installed by HVAC technicians, metalworkers, pipefitters, and maintenance tradespeople who rely on quick disc changes during surface prep, weld blending, and deburring operations.

This disc pad is suited for light-duty to medium-duty surface preparation tasks in residential and commercial maintenance environments. The 1-inch pad size makes it well-suited for tight-access work on tubing, pipe ends, fittings, and sheet metal components. Its compact form factor allows use in confined spaces where larger grinders cannot reach. Tradespeople working in mechanical rooms, equipment closets, and utility chases will find the small pad diameter practical for controlled material removal.

Installation Notes

Thread the pad onto a 1/4-20 mandrel and ensure it is fully seated before attaching a Roloc disc. Always power down and disconnect the grinder or air supply before changing pads or discs. Inspect the pad surface for wear or deformation before each use and replace if the pad body shows cracking or delamination. Follow all applicable workplace safety requirements and tool manufacturer guidelines when operating rotary abrasive tools.
