3M 7010360181 Diamond Lapping Film Disc 4.25 in

Product Description

The 3M 7010360181 is a diamond lapping film disc designed for precision finishing of extremely hard materials. Precisely graded diamond particles are coated onto a polyester film backing, producing a consistent, repeatable surface finish across production runs. The disc measures 4.25 inches in diameter and is available in multiple grades ranging from 0.10 to 30.0 micron. It is used by technicians and machinists who require tight surface tolerances on hard substrates such as ceramics, carbide, optical components, and hardened metals. The polyester film base resists tearing and maintains dimensional stability during wet or dry lapping operations.

This disc is suited for precision lapping and polishing applications in optical, aerospace, electronics, and industrial manufacturing environments. It fits standard lapping fixtures and polishing machines that accept 4.25-inch diameter film discs. The 0.10 to 30.0 micron grade range covers both aggressive stock removal and fine finishing stages, allowing technicians to progress through a complete lapping sequence using the same disc format. Minimum order quantity is 25 units per order.

Key Features

• Precisely graded diamond abrasive particles bonded to polyester film for uniform cut rate
• Consistent, repeatable finish on extremely hard materials including ceramics and carbide
• Available in grades from 0.10 to 30.0 micron to cover roughing through fine finishing
• Polyester film backing provides dimensional stability and resistance to tearing
• Available format options include discs, sheets, and rolls
• Fast cut rate supports higher throughput in production lapping operations

Compatibility

Designed for use on standard lapping and polishing equipment accepting 4.25-inch diameter film discs. Suitable for finishing extremely hard materials such as ceramics, hardened metals, carbide, and optical components where a controlled, uniform surface finish is required.

Installation Notes

Lapping film discs of this type are typically installed and replaced by machinists or precision finishing technicians. Ensure the lapping plate or fixture surface is clean and free of debris before mounting the disc to avoid contamination of the abrasive layer. Follow equipment manufacturer guidelines for disc attachment, whether pressure-sensitive, magnetic, or mechanical. Inspect the disc for tears or uneven wear before each use and replace when consistent cut rate can no longer be maintained.
