Products Description
- 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
3M 372L Microfinishing Film Roll, 2.36 in x 492 ft x 3 in 30 Micron ASO, 5 per case
An aluminum oxide micron roll resin bonded to a 5 mil polyester film backing. The backing has a friction grip coating for slip resistance. Precision finishing of cylindrical surfaces such as automotive camshafts & crankshafts.
Film Backing Provides Uniformly Flat Vehicle for Finer Finish
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, the polyester film backing flexes to help achieve a consistent finish over contours and is stronger than comparable paper products, making it ideal for high-production environments.

*Suggest to specify the 372L or 373L type 2 (colored) film whenever possible to assist with Error-proofing.
*European Lead Product. Plus wide rolls and belts globally.
An aluminium oxide micron roll resin bonded to a 127 micron polyester film backing. The backing has a friction grip coating for slip resistance. Precision finishing of cylindrical surfaces such as automotive camshafts & crankshafts.
Precision micron-grade aluminium oxide, load resistant free-cut coating for fibreglass, wood, metals and solid surface.
- High strength film backing and micron-graded aluminium oxide mineral provides precise, uniform, close-tolerance finishes
- Fast cutting
- Long length rolls
Engine component surfaces and geometry can be improved by using microfinishing which removes variations in the surface, minimizes friction and manipulates metal behavior in other ways.
Recommended Applications
3M 372L Microfinishing Films are used in the production of industrial components such as custom flanges and fittings for the oil and gas industry, as well as superfinishing of automotive parts, like crankshafts, camshafts and transmission parts.
