3M 7000000363 Microfinishing Film Roll 60 Micron 4x150 Ft

Product Description

The 3M 7000000363 is a microfinishing film abrasive roll designed for precise, close-tolerance surface finishing across metal, plastic, and painted substrates. Built on a high-strength polyester film backing with resin-bonded abrasive, the 472L construction delivers fast, consistent stock removal while maintaining tight finish tolerances. At 60 micron grit and 5 MIL film thickness, this roll suits applications where surface geometry and finish uniformity are critical. The keyed core design locks the roll into compatible holders to prevent slippage during operation. Weighing 1.69 pounds per roll, it is sized at 4 inches wide by 150 feet long, making it suitable for both bench-mounted and machine-fed finishing setups.

This microfinishing film roll is used in metalworking and manufacturing environments where controlled, repeatable finishes are required. Typical applications include automotive powertrain component superfinishing, roll superfinishing, metal deburring, plastic surface preparation, and automotive paint spot repair. The Type E construction and polyester film backing hold dimensional stability under the tension and heat generated in high-cycle production finishing. Trades and shops working with precision machined parts or finishing lines are the primary users of this product.

Key Features

• 60 micron aluminum oxide abrasive for fast cutting with uniform finish results
• 5 MIL high-strength polyester film backing provides dimensional stability under load
• Resin-bonded abrasive construction extends roll life in production environments
• Keyed core prevents roll slippage in compatible machine holders
• 4 inches x 150 feet roll format suits bench and machine-fed finishing applications
• Suitable for metal, plastic, paint spot repair, and powertrain component superfinishing

Compatibility

Designed for use with keyed-core microfinishing film holders and roll superfinishing machines that accept a 3-inch core, 4-inch wide film roll. Confirm core and holder compatibility before installation.

Installation Notes

Installation is typically performed by machinists or surface finishing technicians. Power down and lock out any machine before loading or threading the roll. Verify that the keyed core seats fully in the holder to prevent lateral movement during operation. Follow the machine manufacturer's tension and feed rate specifications to avoid film tearing or uneven wear.
