3M 7100010386 Roloc Disc Pad Soft 3 in 1/4-20

Product Description

The 3M 7100010386 is a soft backup pad engineered to support 3-inch Roloc abrasive discs in grinding, blending, and finishing applications. The pad features a 1/4-20 internal thread that mounts directly to tools with a 1/4-20 external threaded shaft, or pairs with a Roloc shank adapter to fit collet chuck tools. Weighing just 0.22 pounds, the soft durometer construction allows the disc face to conform to contoured and irregular surfaces, maintaining consistent abrasive contact across the workpiece. This pad is installed by metalworking fabricators, auto body technicians, and maintenance professionals who rely on Roloc quick-change disc systems for fast disc swaps during production work.

This backup pad is suited for use on angle grinders, die grinders, and collet chuck tools where a 3-inch quick-change abrasive disc format is specified. The soft pad grade is preferred when working on curved panels, weld seams, or contoured metal surfaces where a rigid pad would reduce disc contact and leave uneven finish patterns. It is a common component in body shop, fabrication shop, and MRO environments running 3-inch Roloc disc systems.

Key Features

• Supports 3-inch diameter Roloc quick-change abrasive discs
• 1/4-20 internal thread mounts directly to tools with 1/4-20 external threaded shafts
• Compatible with Roloc shank adapters for use in collet chuck tools
• Soft durometer pad face conforms to contoured and irregular workpiece surfaces
• Lightweight at 0.22 pounds for reduced operator fatigue during extended use

Compatibility

Designed for use with 3-inch diameter Roloc abrasive discs. Mounts to tools with 1/4-20 external threaded shafts or accepts a Roloc shank for collet chuck tool compatibility.

Installation Notes

Thread the pad onto the tool shaft hand-tight before seating the abrasive disc into the Roloc hub. Power down and disconnect or lock out the tool before changing discs or removing the backup pad. Inspect the pad face for wear, tearing, or deformation before each use and replace if the surface is no longer flat and intact. Follow tool manufacturer torque and speed rating guidelines when selecting compatible abrasive discs.
