Our 3M™ Microfinishing Film Roll 372L features micron-graded premium aluminum oxide bonded to a 5 mil polyester film backing to deliver uniform results and meet stringent surface requirements. A friction grip coating provides slip resistance for microfinishing machines where film slippage is an issue, and close tolerance work on cylindrical surfaces, such as automotive camshafts and crankshafts.
Available in a range of grades to help operators achieve goal tolerances. Color-coded by grade for error proofing. Durable polyester film backing provides flexibility for consistent finishing on contoured surfaces. Micron-graded aluminum oxide abrasive cuts fast and provides a consistent, fine finish. Polyester film backing can be run wet
