3M 7010360233 Diamond Lapping Film Disc 4 Inch

Product Description

The 3M 7010360233 is a diamond lapping film disc designed for precision finishing of extremely hard materials. The disc features precisely graded diamond particles coated onto a durable polyester film substrate. This construction delivers a consistent, repeatable surface finish with flat geometry and sharp edge retention. At 4 inches in diameter, it is sized for use with standard lapping fixtures and rotary finishing equipment. Machinists, tool and die technicians, and precision finishing professionals use this disc when working materials that conventional abrasives cannot effectively process.

This disc is suited for applications requiring tight surface finish tolerances on hard substrates such as ceramics, carbide, glass, and hardened steel. It performs well in both wet and dry lapping setups and is a common choice for optical component finishing, fiber optic connector polishing, and precision tooling work. Available grades span 0.10 to 30.0 micron, allowing the user to select the correct cut rate and finish level for the specific operation.

Key Features

• Precisely graded diamond abrasive particles for consistent, repeatable finish results
• Polyester film backing provides dimensional stability and support for flat lapping
• 4 inch diameter fits standard lapping disc fixtures and rotary equipment
• Fast cut rate increases throughput on hard-to-abrade materials
• Produces flat surfaces and sharp edges with uniform finish quality
• Available in multiple grades from 0.10 to 30.0 micron to match application requirements

Compatibility

Designed as an OEM-style replacement or direct-use disc for standard 4 inch lapping and polishing fixtures used in precision metalworking, optical, and fiber optic finishing applications.

Installation Notes

Diamond lapping film discs are typically installed and used by precision machinists or finishing technicians. Secure the disc flat against the lapping plate or backing fixture before use to prevent edge lifting and uneven wear. Inspect the disc surface before each use and replace when diamond particle depletion or backing damage is observed. Follow equipment manufacturer guidelines for rotational speed and applied pressure to avoid premature disc wear or substrate damage.
