3M 7100173800 Scotch-brite 4 Inch Non-woven Abrasive Disc

Product Description

The 3M 7100173800 is a Scotch-Brite XC-ZS Clean and Strip XT Pro Extra Cut non-woven abrasive disc built for aggressive surface preparation. It incorporates aluminum oxide mineral into an open nylon web, allowing it to cut through heavy rust, thick paint, and corrosion while simultaneously cleaning down to bare metal. The 4-inch diameter disc mounts via a 1/2-inch arbor and is rated for high-speed operation with low vibration. Licensed HVAC technicians, welders, fabricators, and maintenance professionals use this disc for weld cleaning, rust removal, and pre-coating surface prep.

This disc is suited for residential and commercial maintenance, metal fabrication shops, and field service work where surface condition matters before coating, welding, or assembly. The open nylon web construction resists loading, meaning the disc maintains consistent cutting action throughout its service life. Its high conformability increases the contact patch against curved or irregular surfaces, improving removal rates on pipes, structural steel, sheet metal, and similar substrates. It performs particularly well on edges where rigid abrasives tend to skip or chatter.

Key Features

• Aluminum oxide mineral aggressively removes rust, thick paint, and corrosion down to bare metal
• Open nylon web construction resists loading for consistent, sustained cutting action
• High conformability increases contact patch on curved and irregular surfaces
• High-strength fibers resist chunking and maintain performance on edges
• High speed rating with low vibration for operator comfort during extended use
• 4-inch diameter with 1/2-inch arbor mount for common angle grinder and disc tool fitment

Compatibility

Designed for use on angle grinders and disc tools accepting a 4-inch non-woven abrasive disc with a 1/2-inch arbor. Verify tool speed rating does not exceed the disc maximum RPM before mounting.

Installation Notes

Installation and tool operation should follow ANSI B7.1 safety standards for abrasive products. Disconnect and de-energize the tool before mounting or removing the disc. Inspect the disc for damage before each use and confirm the tool spindle speed does not exceed the disc speed rating. Eye protection, gloves, and appropriate respiratory PPE are standard practice when operating non-woven abrasive discs.
