3M 7000008926 Microfinishing Film Roll 362L 40 Micron

Product Description

The 3M 7000008926 is a microfinishing film roll designed for precise, uniform, close-tolerance surface finishing on metal, plastic, and paint. Built on a high-strength polyester film backing with resin-bonded abrasive, this roll delivers fast cutting action while maintaining dimensional accuracy across the finished surface. The 40-micron grit rating targets intermediate finishing stages where consistent stock removal and surface uniformity are critical. It measures 4 inches wide by 150 feet long on a 3-inch keyed core. Licensed trades and precision finishing technicians working on tight-tolerance components rely on this format for repeatable results in production and repair environments.

This roll is suited for metal components, plastic substrates, paint spot repair, and automotive powertrain parts requiring controlled surface refinement. The ASO (anti-static open) construction and keyed core design make it compatible with roll superfinishing equipment used in automotive, aerospace, and precision manufacturing applications. It is appropriate for both production-line finishing and detail repair work where surface finish uniformity is a process requirement rather than an aesthetic preference.

Key Features

• 40-micron abrasive rating for precise, close-tolerance finishing
• High-strength polyester film backing for dimensional stability and durability
• Resin-bonded abrasive construction resists shedding during aggressive stock removal
• ASO (anti-static open) designation reduces static buildup on sensitive components
• Keyed core design for secure, repeatable positioning on compatible superfinishing equipment
• 150-foot roll length supports extended production runs with minimal changeover

Compatibility

Designed for use on metal, plastic, paint surfaces, and automotive powertrain components in roll superfinishing applications requiring a 4-inch wide, 3-inch keyed core format.

Installation Notes

Loading is performed on roll superfinishing machines or film-feed finishing equipment compatible with a 3-inch keyed core. Power down and de-energize all equipment before threading or replacing the film roll. Ensure the keyed core seats fully and locks before resuming operation to prevent roll slippage during use. Follow equipment manufacturer guidelines and applicable shop safety standards when handling abrasive film rolls under tension.
