3M 7000000333 Microfinishing Film Roll 362L 60 Micron

Product Description

The 3M 7000000333 is a precision microfinishing film roll in the 362L series, designed for close-tolerance surface finishing across a range of materials. The roll measures 4 inches wide by 150 feet long with a 3-inch keyed core and carries a 60-micron aluminum oxide abrasive grade. The high-strength polyester film backing is resin-bonded for consistent cutting action and durability under repeated use. An anti-loading free-cut coating keeps the abrasive open during use, maintaining cut rate and surface uniformity. This roll is suited for applications where precise, repeatable finishes are required and standard sandpaper cannot hold the necessary tolerances.

This microfinishing film is used in metal fabrication, automotive powertrain component finishing, roll superfinishing, and spot repair work on paint and plastic. It performs on metal, plastic, fiberglass, wood, and solid surface materials. The keyed core design is intended for use with compatible roll-finishing machines and fixtures that accept a 3-inch keyed arbor. It is commonly specified in production-finishing environments as well as in precision automotive and machine shop applications where micron-grade abrasives are standard.

Key Features

• 60-micron aluminum oxide abrasive for precise, uniform material removal
• High-strength polyester film backing resin-bonded for durability and dimensional stability
• Anti-loading free-cut coating maintains cut rate and reduces loading on softer materials
• 3-inch keyed core for secure, repeatable positioning on compatible finishing equipment
• Suitable for metal, plastic, fiberglass, wood, paint, and solid surface applications
• 150-foot roll length reduces changeover frequency in production settings

Compatibility

Designed for use with roll-finishing machines and fixtures that accept a 3-inch keyed core. Suitable for superfinishing, close-tolerance metalworking, automotive powertrain component finishing, and precision surface refinishing applications.

Installation Notes

Installation onto a finishing machine should be performed with the equipment powered down and all rotating components at a full stop. Verify that the keyed core seats fully and securely on the arbor before resuming operation. Follow the equipment manufacturer's guidelines for roll tension and feed rate. Wear appropriate personal protective equipment, including eye protection, when operating abrasive finishing equipment.
