Review on πŸ”΄ 50 Carton 3M Hookit Purple Clean Sanding Discs 343U, 30272, P500 by Roy Niemeyer

Revainrating 4 out of 5

I'm disappointed with disc punctures as it happens.

I initially ordered these to replace the 3M 00912 (500 grit) abrasive discs that are used to clean headlight lenses as I could not find the 3M 00912 disc drill/arbor assembly. Although the abrasive material is of high quality, I ordered the correct 3" grinding wheel (3M 00912) and will likely use this 3M 30272 perforated grinding wheel for a variety of hand sanding jobs.

Pros
  • Fine edge sanding, last sanding pass before priming or priming.
Cons
  • Reliability
