3M 7010360189 Diamond Lapping Film Disc 12 Inch

Product Description

The 3M 7010360189 is a diamond lapping film disc designed for precision surface finishing on extremely hard materials. Precisely graded diamond particles are coated onto a durable polyester film backing, delivering a consistent, repeatable finish across each use. The 12-inch diameter disc is suited for demanding lapping and polishing operations where surface flatness, edge sharpness, and finish uniformity are critical. Abrasive technicians, tool-and-die professionals, and precision fabricators rely on this disc for applications requiring tight tolerances. The polyester film carrier maintains dimensional stability during use, supporting accurate material removal at each pass.

This disc is used in lapping and polishing operations on hard substrates including ceramics, carbides, optical components, and hardened metals. It is well suited for both bench-top lapping machines and manual finishing setups. The 12-inch format accommodates standard lapping plates and flat-lap machines common in precision machining, optical fabrication, and advanced materials finishing environments. The disc format allows for quick changeovers when working through a sequence of finishing grades.

Key Features

• Precisely graded diamond abrasive particles for controlled, repeatable material removal
• Polyester film backing provides dimensional stability and supports flat surface geometry
• Fast cut rate increases throughput on hard-to-abrade materials
• Produces uniform finish with flat surfaces and sharp edges
• Available in multiple grades ranging from 0.10 to 30.0 micron for staged finishing sequences

Compatibility

Designed for use on extremely hard materials including ceramics, carbides, optical glass, and hardened metals. Fits standard 12-inch lapping plates and flat-lap machines. Consult grade selection guides when sequencing multiple micron ratings for a given substrate.

Installation Notes

Mounting and use of lapping film discs should follow the equipment manufacturer's guidelines for adhesive-backed or pressure-sensitive disc mounting. Ensure the lapping plate surface is clean and free of debris before applying the disc to prevent surface irregularities. Use appropriate personal protective equipment when handling diamond abrasive products. Inspect the disc for tears or uneven abrasive coating before each use.
