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

PRODUCT FAQ
-
What is the 3M™ Microfinishing Film Roll 372L used for?
The 3M™ Microfinishing Film Roll 372L is designed to provide precision finishing on a variety of metals, including stainless steel, titanium, and nickel alloys.
-
Is the roll size suitable for my needs in terms of length and width?
Absolutely. The film roll measures 0.807 inches (20.5mm) in width, has a length of 300 feet (91.5m), and features a convenient plastic core for easy installation.
-
How many rolls come in each case?
Each case contains fifteen (15) rolls individually wrapped to ensure that they stay clean and ready-to-use.
-
What kind of backing does this micro-finishing film feature?
This product features an ASO (Anti-Slip-Out) coating which keeps the abrasive particles securely attached and ensures consistent performance throughout its use, as well as ERMB (Extended Range Microreplication Backing) technology which delivers highly uniform finishes with minimal scratch patterns.
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.
