The 3M? Microfinishing Film Roll 372L features micron-graded premium aluminum oxide bonded to a 5 mil (0.13 mm) 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.

Anything extra you need to know
In order to achieve a consistent scratch for microfinishing, the 3M? Microfinishing Film Roll 372L features micron-graded mineral, measured at very tight size tolerances
This roll's resin bond ensures reliable, consistent performance
With a durable film backing, the abrasive can navigate tight geometry and finish tolerances
This microfinishing roll comes in a broad range of micron grades to achieve a consistent finish without altering part geometry
To reduce risk of operator error, Type 2 film was designed in a range of colours, reflective of each grade
The colour coding is a useful visual cue, as is sorting width by core size and side and end of roll printing and marking
Film backings provide a superior, uniformly flat surface to hold abrasive particles ? abrasive grains don?t compress or become pressed into the backing
Highly conformable and tear-resistant, this roll's polyester film backing flexes to help achieve a consistent finish over contours and is stronger than other 3M? Abrasives, making it ideal for high-production environments
Manufacturers of critical automotive components have little room for error in producing parts to specification
Engine component surfaces and geometry can be improved by using microfinishing which removes variations on the surface, minimizes friction, and manipulates metal behaviour in other ways.
What makes this product special
Micron-graded aluminum oxide abrasive cuts fast and provides a consistent, fine finish
Durable polyester film backing provides flexibility for consistent finishing on contoured surfaces
Polyester film backing can be run wet
Available in a range of grades to help operators achieve goal tolerances
Color-coded by grade for error proofing
