3M 7010307687 Diamond Lapping Film 661X 15.0 Micron Roll

Product Description

The 3M 7010307687 is a diamond lapping film designed for precision surface finishing on extremely hard materials. Precisely graded diamond abrasive particles are coated onto a dimensionally stable polyester film backing, delivering a consistent, repeatable finish pass after pass. This roll measures 1.50 inches wide by 50 feet long and carries a 15.0 micron grade, placing it in the mid-range of the 661X series lineup that spans 0.10 to 30.0 micron. It is used wherever tight surface finish tolerances are required and conventional abrasives fall short.

This lapping film is suited for precision finishing applications across industries that demand controlled material removal and smooth surface profiles. Typical uses include finishing optical fiber connectors, ceramic components, carbide tooling, and other hard substrates. The roll format suits bench lapping fixtures, automated finishing equipment, and custom tooling setups. Machinists, toolmakers, and precision technicians in manufacturing, optical, and specialty trade environments are the primary installers and users of this product.
