3M 7100173790 Scotch-brite Roloc 3 Inch Strip Disc Ao

Product Description

The 3M 7100173790 is a Scotch-Brite Roloc Clean and Strip XT Pro Extra Cut Disc built for aggressive surface preparation on metal. Aluminum oxide abrasive mineral is incorporated into an open nylon web, giving the disc the cutting action needed to remove heavy rust, thick paint, corrosion, and weld scale down to bare metal in a single pass. At 3 inches in diameter, it mounts via the Roloc twist-on attachment system, making disc swaps fast during production work. High-strength, conformable fibers resist chunking and loading, maintaining consistent cut rate through the life of the disc.

This disc is suited for metal fabrication, automotive body repair, maintenance welding, and industrial surface prep where stripping to bare substrate is required before coating or welding. The open web construction resists loading on painted or corroded surfaces, and the disc conforms well to contoured workpieces and edges. It is typically run by fabricators, welders, body technicians, and industrial maintenance trades using angle grinders or die grinders equipped with a compatible Roloc backup pad.

Key Features

• Aluminum oxide mineral aggressively strips heavy rust, thick paint, and corrosion to bare metal
• Open nylon web construction resists loading for consistent cutting action throughout disc life
• High-conformability fibers increase contact patch on contoured surfaces and edges
• High-strength fibers resist chunking under aggressive pressure
• Roloc twist-on attachment system enables fast disc changes without tools
• High speed rating with low vibration for operator comfort during extended use

Compatibility

Requires a compatible Roloc backup pad, sold separately. Designed for use with angle grinders and die grinders equipped with a Roloc-style backup pad rated for the disc speed.

Installation Notes

Installation and removal are performed by twisting the disc onto and off of a Roloc backup pad — no wrenches required. Confirm the backup pad speed rating meets or exceeds the disc speed rating before mounting. Wear appropriate eye and face protection, and ensure guards are in place before operating. Power down and disconnect the tool before changing discs.
