3M 7010298847 Diamond Lapping Film 30 Micron 9x11 in

Product Description

The 3M 7010298847 is a diamond lapping film sheet engineered for precision abrasive finishing work. Built on a reinforced resin system, this film delivers added toughness and extended service life compared to standard lapping films. At 30.0 micron grit, it removes material at a controlled rate while producing a consistent, fine surface finish. The sheet measures 9 inches x 11 inches and is sold individually. Superfinishing technicians, precision machinists, and tool-and-die professionals rely on this product when tight surface-finish tolerances are required.

This diamond lapping film is used primarily in superfinishing, roll polishing, and flat lapping applications. It performs on hard substrates including carbide, ceramics, and hardened steel where conventional abrasive films wear prematurely. The 30.0 micron grade positions it in the medium-cut range of the 663X series lineup, which also includes 45.0 and 60.0 micron options for staged finishing sequences.

Key Features

• Stronger resin bond system provides added film toughness and longer working life
• 30.0 micron diamond abrasive grade for controlled material removal and fine surface finish
• 9 inches x 11 inches sheet format fits standard flat lapping fixtures and roll polishing setups
• Suited for superfinishing, roll polishing, and flat lapping operations
• Part of a multi-grade series (30.0, 45.0, and 60.0 micron) to support progressive finishing sequences

Compatibility

Designed for use in flat lapping, superfinishing, and roll polishing applications where diamond abrasive film is specified. Consult equipment manufacturer guidelines to confirm sheet size and backing compatibility with your lapping fixture or polishing system.

Installation Notes

Diamond lapping film should be mounted to a flat, clean lapping plate or fixture free of debris that could cause uneven wear or scratching. Secure the sheet evenly to prevent slipping during operation. Use appropriate coolant or lubricant as specified for the workpiece material and application. Replace the sheet when cut rate or surface finish quality degrades noticeably.
