3M 7000000330 Microfinishing Film Roll 362L 9 Micron

Product Description

The 3M 7000000330 is a precision microfinishing film roll in the 362L series, designed for fast-cutting abrasive finishing to achieve precise, uniform, close-tolerance surface results. The roll measures 4 inches wide by 150 feet long, with a 3-inch core, and carries a 9-micron aluminum oxide abrasive grade. The backing is a high-strength polyester film with resin-bonded construction for consistent performance and durability under continuous use. An anti-loading free-cut coating keeps the abrasive surface clear during operation, maintaining cut rate across the full roll length. This product is used by machinists, automotive technicians, and finishing specialists working with tight surface tolerance requirements.

This microfinishing film roll is suited for roll superfinishing operations and precision surface finishing on metal components, plastic parts, fiberglass, wood, and solid surfaces. Typical applications include automotive powertrain component finishing, paint spot repair, and close-tolerance metal finishing where consistent micron-grade stock removal is required. The 9-micron aluminum oxide formulation delivers repeatable results across both manual and machine-driven finishing setups. It is sold by the roll, with a minimum order quantity of 4 rolls.
