3M 7000021279 Scotch-brite Roloc Disc 1 Inch Very Fine

Product Description

The 3M 7000021279 is a Scotch-Brite Roloc surface conditioning disc built for deburring, cleaning, blending, and finishing on metal and fabricated surfaces. The disc uses a non-woven fiber construction bonded to a Roloc quick-change backing. The open-web design resists loading and runs cool, which supports consistent finish quality across multi-step surface prep operations. At 1 inch in diameter, this disc fits compact right-angle tools commonly used by metalworkers, fabricators, and maintenance technicians working in tight or contoured areas.

This disc is suited for light deburring, edge blending, and surface finishing on irregular or contoured workpieces where conformability matters. The non-woven construction flexes to follow surface geometry rather than cutting through it, making it appropriate for finish work where preserving the base material profile is a priority. The Very Fine grade targets final finishing and light cleaning passes rather than heavy stock removal. Typical applications include weld preparation, part deburring, and pre-coat surface conditioning in fabrication shops and maintenance environments.

Key Features

• Non-woven fiber construction conforms to irregular and contoured surfaces
• Open-web design resists loading and dissipates heat for consistent finishes
• Roloc quick-change backing allows fast disc swaps during multi-step finishing sequences
• Very Fine abrasive grade suited for blending, light deburring, and surface conditioning
• 1 inch diameter fits compact rotary and right-angle tools in confined work areas

Compatibility

Designed for use with Roloc-compatible quick-change tool mandrels on standard rotary tools and right-angle grinders that accept the Roloc attachment system.

Installation Notes

Installation is performed by pressing the disc onto a Roloc-compatible mandrel and rotating to lock. Ensure the tool is powered off and disconnected before changing discs. Verify the tool RPM rating does not exceed the disc maximum rated speed before operation. Eye protection and appropriate PPE should be worn during use.
