3M 7100033115 Diamond Lapping Film Roll 45.0 Micron

Product Description

The 3M 7100033115 is a diamond lapping film supplied in roll form, designed for precision surface finishing in industrial and trade applications. At 45.0 micron grit, it delivers consistent stock removal and a controlled surface finish across flat, cylindrical, and contoured workpieces. The film is built on a stronger resin system that bonds the diamond abrasive more securely to the backing, resulting in added toughness and extended service life compared to standard lapping films. It is typically handled by machinists, tool-and-die technicians, and precision grinding specialists who require repeatable, measurable surface finish results.

This lapping film is used primarily in superfinishing, roll polishing, and flat lapping operations. The 2-inch width and 50-foot roll length make it well suited for continuous polishing setups, automated lapping machines, and manual hand-lapping fixtures. The 45.0 micron grade sits in the mid-range of the available product line, which also includes 30.0 and 60.0 micron grades, allowing technicians to step through finishing sequences from aggressive stock removal down to finer surface refinement.

Key Features

• 45.0 micron diamond abrasive grade for controlled mid-range stock removal and surface finishing
• Stronger resin bond system provides added film toughness and longer working life
• Roll format — 2 inches wide by 50 feet — suits automated and manual lapping setups
• Suitable for superfinishing, roll polishing, and flat lapping applications
• Also available in 30.0 and 60.0 micron grades for multi-step finishing sequences

Compatibility

Designed for use in superfinishing, roll polishing, and flat lapping applications where a 2-inch wide diamond lapping film roll in the 45.0 micron grade is required.

Installation Notes

Installation and use of lapping film should be performed by qualified machinists or finishing technicians familiar with lapping equipment and surface-finish requirements. Ensure the lapping machine or fixture is powered down and secured before loading or threading the film roll. Keep the film surface free of contamination — oils, debris, or moisture on the workpiece can reduce abrasive effectiveness and shorten film life. Follow equipment manufacturer guidelines for tension, feed rate, and coolant application.
