3M 272L Microfinishing Film Roll, 9 Mic 5MIL, 3 in x 230 ft (4 per case)

The 3M 272L microfinishing film roll supports precision polishing and finishing across demanding microfinishing applications. Designed for controlled material refinement, this microfinishing film performs well in cylindrical grinding, centerless grinding and roll superfinishing processes. Many automotive powertrain components benefit from the flexible construction, especially parts with tight tolerances or complex geometries.

Supplied as a roll, the 3M 272L microfinishing film offers flexibility for custom cutting and shaping to match specific part dimensions. Operators can use the roll by hand or with automated microfinishing equipment, supporting consistent results across production environments.

Aluminum Oxide Abrasive for Consistent Microfinishing

3M anchors aluminum oxide mineral to a durable polyester film backing using a resin bond. Aluminum oxide remains a preferred abrasive among industrial users due to fast cutting action, wear resistance, and stable performance during extended runs. The abrasive grain structure supports controlled stock removal while maintaining fine surface finishes required in microfinishing operations.

Water-Resistant Polyester Film Backing

The 3M 272L microfinishing film roll features a 5 mil polyester backing designed for flexibility, caliper consistency and dimensional stability. Film-backed abrasives perform well in microfinishing applications where uniform pressure and repeatable results drive quality outcomes. A friction-coated backing helps reduce slippage during operation, supporting consistent finishes from part to part.

Polyester construction supports wet or dry use. Lubricants such as water help flush swarf and debris away from the abrasive surface, reducing premature dulling and improving finish quality. Resin bonding supports cooler operation during continuous use.

Micron-Graded Options for Process Control

3M 272L microfinishing film rolls are available in a wide range of micron grades from 9 microns to 100 microns. Coarser grades support heavier refinement steps, while finer grades deliver smooth surface finishes during final polishing stages. Color-coded grading simplifies identification when multiple steps are used in sequence.

Performance Advantages of 3M 272L Microfinishing Film

3M microfinishing abrasives help remove traverse marks, reduce chatter, follow existing part geometry and achieve targeted surface roughness values. Impressive performance characteristics support consistent results across metalworking, automotive and precision manufacturing environments.
