3M 7000044853 Diamond Lapping Film Disc 8 Inch

Product Description

The 3M 7000044853 is a diamond lapping film disc engineered for precision surface finishing on extremely hard materials. Precisely graded diamond particles are coated onto a durable polyester film backing, producing a consistent and repeatable surface finish across every pass. The disc measures 8 inches in diameter and is designed for applications where tight surface tolerances are critical. Machinists, optical technicians, and tooling professionals use this disc to achieve flat surfaces and sharp edges on ceramics, carbides, hardened steels, and similar substrates.

This lapping film disc is suited for flat lapping, edge finishing, and polishing operations in precision manufacturing, optics, and tooling environments. The polyester film backing provides dimensional stability during use, which helps maintain contact consistency across the full disc surface. The diamond abrasive grade range of 0.10 to 30.0 micron makes this product applicable across rough stock removal and fine finishing stages depending on the grade selected. It is sold individually and is compatible with standard 8-inch lapping plates and fixture setups used in professional shops.

Key Features

• Precisely graded diamond particles on polyester film backing for repeatable surface finish
• Available in grades ranging from 0.10 to 30.0 micron for multi-stage finishing
• Flat surface and sharp edge results on extremely hard materials
• Fast cut rate supports increased throughput in production environments
• Uniform finish across the full disc surface
• Available in disc, sheet, and roll formats

Compatibility

Designed for use on standard 8-inch lapping plates and fixtures in precision surface finishing applications involving hard materials such as ceramics, carbides, and hardened tooling steels.

Installation Notes

This disc is installed by precision machinists or tooling technicians on flat lapping plates or fixture-mounted systems. Ensure the lapping plate surface is clean and free of debris before mounting the disc to maintain full surface contact. Follow the equipment manufacturer guidelines for disc retention and fluid or lubricant use during lapping operations. Inspect the disc for wear before each use and replace when abrasive performance degrades.
