3M 7100135201 Diamond Lapping Film Disc 4 Inch

Product Description

The 3M 7100135201 is a 4-inch diameter diamond lapping film disc designed for precision surface finishing on extremely hard materials. The disc is constructed from a polyester film base coated with precisely graded diamond abrasive particles. This construction delivers a consistent, repeatable finish across applications where surface geometry and edge sharpness are critical. It is used by machinists, tool and die technicians, fiber optic polishing technicians, and other trades that require controlled material removal on hard substrates. The diamond abrasive is available across multiple grades ranging from 0.10 to 30.0 micron.

This lapping film disc fits into precision finishing workflows for carbide tooling, ceramics, glass, optical components, and fiber optic connectors. The 4-inch disc format is suited for use on lapping plates, polishing fixtures, and backing pads in both bench and production environments. Its polyester film base maintains dimensional stability under light to moderate pressure, making it appropriate for applications that require flat surfaces and sharp, burr-free edges.

Key Features

• Precisely graded diamond particles for controlled, repeatable material removal
• Polyester film backing maintains flatness and dimensional stability
• Fast cut rate supports higher throughput in production finishing
• Produces flat surfaces and sharp edges on hard materials
• Available in grades from 0.10 to 30.0 micron for coarse through fine finishing
• Disc format compatible with standard lapping plates and backing fixtures

Compatibility

Designed for use on extremely hard materials including carbide, ceramics, glass, and optical substrates. Compatible with standard lapping plates and polishing fixtures that accept 4-inch diameter film discs.

Installation Notes

Mount the disc onto a clean, flat lapping plate or appropriate backing pad before use. Ensure the work surface and fixture are free of contamination that could cause inconsistent contact or scratching. Apply only light, consistent pressure during lapping to preserve the abrasive coating and maintain surface geometry. Handling and use should follow the manufacturer's guidelines for the specific micron grade selected.
