The 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.
- 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

-
Each case has seven rolls that measure approximately 623 feet each.
What grit does it offer?
-
It comes with a pre-defined grain size of up to 30 microns on its abrasive side.
Is there any key feature or specialty associated with this product?
-
Yes! This model rolls come equipped with Keyed Cores to eliminate machine slips and make loading/unloading quicker so you can get back to work faster!
Is there any specific range regarding how much pressure to apply when using these films?
-
The recommended value varies from material to material - be sure not over-aggressively force it onto your surface and refer directly to our General Polishing Guide documentation that we have available upon request!
3M™ Microfinishing Film Roll 372L achieves an extremely consistent scratch for microfinishing by using micron-graded mineral, measured at tight size tolerances. The resin bond ensures reliable, consistent performance. The abrasive has a durable film backing that helps achieve tight geometry and finish tolerances. This microfinishing roll comes in a broad range of micron grades to achieve reproducible surface characteristics and geometric values that adhere to specification.
3M designed Type 2 film in a range of colors to reduce the risk of operator error. The color coding is a useful visual cue, as is sorting width by core size and side and end of roll printing and marking. In some applications, numerous grades are run simultaneously to achieve finishes that differ across the surface of a single complex part.
Film Backing Provides Uniformly Flat Vehicle for Finer FinishFilm backings provide a superior, uniformly flat surface to hold abrasive particles. Abrasive grains don't compress or become pressed into the backing. The polyester film backing is highly conformable and tear-resistant, flexing to help achieve a consistent finish over contours. It is stronger than comparable paper products, making it ideal for high-production environments.
For Flawless GeometriesManufacturers of critical automotive components have little room for error in producing parts to specification. Microfinishing removes variations in the surface, minimizes friction, and manipulates metal behavior in other ways. Engine component surfaces and geometry can be improved by using microfinishing, which is essential for finishes of crankshafts and camshafts that rotate on increasingly thinner films of oil.
Recommended Applications3M™ 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.
A Portfolio of Abrasive Systems Solutions3M provides a broad portfolio of abrasives that shape, finish, and polish with ease and precision. From specialty abrasives designed for a highly specific purpose to versatile, jack-of-all-trades sheets, you can find an abrasive tool to accomplish your task or perfect your system. 3M draws from a wealth of original technologies and breakthrough inventions to provide a broad portfolio of abrasives.
