6" PSA Mirka Galaxy Ceramic Sanding Discs

Mirka Galaxy Ceramic discs are engineered for high performance, long life, and consistent cutting power. The advanced ceramic grain is designed to stay sharp by continuously fracturing during use, exposing fresh cutting edges. This results in faster cutting, reduced heat buildup, and significantly longer life compared to conventional abrasive discs.

These 6" PSA (Pressure Sensitive Adhesive) discs provide a strong, secure bond to your backing pad, making them ideal for use on 6" rotating platens commonly used for sharpening scissors, knives, and other cutting tools.

  • Self-Sharpening Ceramic Grain: Maintains sharpness and cutting efficiency throughout the life of the disc
  • Long-Lasting Performance: Outlasts most aluminum oxide and zirconia discs
  • Cool Cutting Action: Reduces heat buildup, helping prevent burning or discoloration
  • Consistent Finish: Delivers uniform scratch patterns for professional results
  • PSA Backing: Quick and secure stick-on application for smooth operation

Jacob F. ★★★★★

I had to sand down some old lacquer on a car door, and these ceramic discs cut through it without loading up like regular paper. The adhesive backing held firm on the orbital, and I got three full panels out of one disc.

Joseph Q. ★★★★★

These discs saved me so much time on a recent cabinet refinishing job - the ceramic grain keeps cutting long after standard discs would have glazed over. The 6" PSA backing holds tight without any slipping, even on a random orbit sander.

Lucy G. ★★★★★

Switching from a standard aluminum oxide disc was night and day—this PSA backing stuck firmly the whole time, and I'm still using the same disc a week later. It's been sanding down hard clear coat without loading up at all.
