3M 7000120838 Scotch-brite Scuffing Disc 6 in Very Fine

Product Description

The 3M 7000120838 is a 6-inch Scotch-Brite scuffing disc engineered for fast, consistent surface preparation in automotive, industrial, and general workshop applications. Built on an open nylon web with a load-resistant construction, this disc scuffs, cleans, and preps surfaces without loading up with debris. The aluminum oxide mineral delivers sharp cutting action at speeds up to 4000 RPM, making it well-suited for machine scuffing prior to staining, painting, or coating. A hook-and-loop backing allows quick attachment to a compatible backup pad or random orbital sander. Qualified technicians and body shop professionals rely on this disc for repeatable, controlled scuffing results across a variety of substrates.

This disc is designed for everyday surface preparation tasks including scuffing automotive finishes before paint application, cleaning parts ahead of coating, and prepping surfaces prior to staining. The very fine grade delivers consistent scratch patterns without altering part geometry. The flexible nylon fiber construction conforms to surface irregularities, making it effective on contoured panels and irregular shapes. It is a practical alternative to steel wool, as the nylon fibers resist splintering and rusting during use.

Key Features

• 6-inch diameter disc rated to 4000 RPM for machine use with random orbital sanders
• Aluminum oxide mineral provides sharp, fast-cutting abrasive action at very fine grade
• Open nylon web is load-resistant, resisting clogging during extended use to prolong disc life
• Nylon fibers flex to conform to surface contours without distorting part geometry
• Will not splinter or rust, making it a direct alternative to steel wool abrasives
• Hook-and-loop backing allows fast attachment and removal from compatible backup disc pads

Compatibility

Designed for use with hook-and-loop backup disc pads and random orbital sanders that accept 6-inch hook-and-loop discs. Backup pad sold separately.

Installation Notes

Install this disc onto a compatible 6-inch hook-and-loop backup pad before mounting on a random orbital sander. Confirm the tool is powered off and unplugged before attaching or removing the disc. Do not exceed the 4000 RPM speed rating. Inspect the disc and backup pad for wear or damage before each use, and replace the disc when abrasive performance is noticeably reduced.
