3M Coarse, Ceramic, Coated, PSA Sanding Disc, 12", 50 Abrasive Grit, Non-Vacuum, PK 10

The 3M™ 12" PSA cloth disc 777F provides the durability needed for moderate stock removal and surface preparation. A grinding aid on the cloth disc reduces running temperatures and protects heat-sensitive alloys like stainless steel, nickel alloys, and cobalt alloys. The abrasive is bonded to the backing with resin to maintain disc durability under high heat and pressure.

• Use for dimensioning parts, deburring, blending, and finishing castings and forgings
• Ceramic aluminum oxide grain blend surpasses aluminum oxide abrasives in cut-rate and durability
• Heavyweight cloth backing for high-pressure, tough applications
• Use on both ferrous and nonferrous metals
