3M 7010360420 Microfinishing Film Sheet 30 Micron 8.5x11

Product Description

The 3M 7010360420 is a precision microfinishing film sheet designed for fast-cutting abrasive work where close-tolerance surface finishes are required. Built on a high-strength polyester film backing with resin-bonded abrasive grain, this sheet delivers consistent, uniform material removal across a range of substrates. At 30 micron grit size and a 3 mil film thickness, it is engineered for fine finishing operations that demand repeatability. Licensed tradespeople and production finishing technicians in metalworking, automotive, and industrial environments rely on this format for controlled surface preparation.

This microfinishing film sheet measures 8.5 inches by 11 inches, making it compatible with standard hand-lapping, backing plate, and fixture-based finishing setups. It is suited for metal components, plastic surfaces, paint spot repair work, and automotive powertrain parts. It is also used in roll superfinishing applications where consistent grit breakdown and film integrity are critical to maintaining part tolerances. Each sheet is sold individually as a single unit.

Key Features

• 30 micron abrasive rating for precise, close-tolerance surface finishing
• 3 mil high-strength polyester film backing resists tearing during use
• Resin-bonded abrasive construction for durability and consistent cut rate
• Sheet size of 8.5 inches by 11 inches fits standard lapping and fixture applications
• Suitable for metal, plastic, paint repair, and automotive powertrain finishing
• Compatible with roll superfinishing processes requiring uniform grit performance

Compatibility

Designed for use in hand-lapping, fixture-based finishing, and roll superfinishing applications involving metal, plastic, paint surfaces, and automotive powertrain components.

Installation Notes

This abrasive film sheet is used by machinists, automotive technicians, and industrial finishing professionals. Before use, ensure the workpiece surface is clean and free of loose debris that could cause uneven abrasion or film damage. Use with an appropriate backing plate or fixture to maintain consistent pressure and avoid premature wear. Dispose of worn sheets promptly, as degraded abrasive film can introduce surface inconsistencies in close-tolerance work.
