Quick-Change Sanding Disc

This 3M quick-change disc uses aluminum oxide abrasive on a polyester backing for medium-grade surface preparation. The closed-coat construction resists loading during sanding tasks. It fits tools equipped with a TR attachment system and is rated for up to 20,000 RPM. The pack contains 50 discs for extended shop use.

For metal finishing and paint prep

Suited for operators blending scratch patterns or removing light oxidation on metal panels. The medium grit and heat-resistant bonding handle sustained contact without premature wear. Not intended for heavy stock removal or aggressive grinding applications requiring coarse grits.

P150 grit rating

The P150 grade determines the scratch profile and material removal rate for each pass. Select this grit when the workflow calls for a uniform finish before priming or top-coating. Coarser or finer grades will produce different surface profiles.
