3M 7010360256 Diamond Lapping Film 30.0 Micron

Product Description

The 3M 7010360256 is a diamond lapping film sheet designed for precision surface finishing on extremely hard materials. It consists of precisely graded diamond abrasive particles coated onto a dimensionally stable polyester film backing. At 30.0 micron grade, this sheet is suited for stock removal and initial surface conditioning steps in a lapping or polishing sequence. The 8.5 x 11 inch sheet size fits standard flat lapping fixtures and hand-lapping setups. Technicians working on fiber optic connectors, carbide tooling, ceramics, and hardened steel components rely on this film for consistent, repeatable surface finish results across production and maintenance applications.

This lapping film is used in applications requiring tight surface finish control on materials that conventional abrasives cannot effectively cut. Common uses include fiber optic termination polishing, precision tool and die work, ceramic component finishing, and lapping of hardened steel or carbide surfaces. The sheet format is compatible with flat lapping plates, backing pads, and hand-lapping blocks. It is sold individually as a single sheet and is available in additional micron grades ranging from 0.10 to 30.0 micron for multi-step finishing sequences.

Key Features

• 30.0 micron diamond abrasive grade for initial stock removal in lapping sequences
• Precisely graded diamond particles deliver consistent, repeatable surface finish results
• Polyester film backing provides dimensional stability during wet or dry lapping
• 8.5 x 11 inch sheet size fits standard lapping fixtures and backing pads
• Effective on extremely hard materials including carbide, ceramics, and hardened steel
• Part of a multi-grade system ranging from 0.10 to 30.0 micron for full polishing sequences

Compatibility

Designed for use with flat lapping plates, lapping fixtures, and backing pads that accept standard 8.5 x 11 inch sheet abrasives. Suitable for multi-step finishing sequences using the 3M 661X Diamond Lapping Film series across available micron grades.

Installation Notes

This film is installed and used by precision tool technicians, fiber optic splicing technicians, and machinists performing surface finishing work. Secure the sheet firmly to a flat lapping plate or backing pad before use to prevent slippage during the lapping stroke. Ensure the workpiece and lapping surface are clean and free of contamination before starting to avoid scratching from embedded debris. Follow a sequential multi-grade process, moving from coarser to finer micron grades, to achieve the target surface finish.
