3M 7000000295 Lapping Film 261X 30.0 Micron 8.5x11 in

Product Description

The 3M 7000000295 is a precision lapping film sheet designed for controlled micro-finishing and surface polishing applications. Designated as the 261X series, this film features precisely graded 30.0-micron aluminum oxide abrasive particles coated onto a durable 3 mil polyester film backing. The consistent particle sizing produces repeatable, uniform finishes across a wide range of substrates. Each sheet measures 8.5 inches x 11 inches and is sold individually. This product is used by technicians and precision finishing professionals who require tight surface finish tolerances in optical, mechanical, and electronic component work.

The 261X lapping film is suited for flat-lapping and draw-filing operations on metal, ceramic, glass, and composite substrates. The 30.0-micron grade is typically used in early-stage stock removal or as an intermediate step in a multi-stage finishing sequence progressing to finer grades. Technicians working on fiber optic connectors, precision tool edges, pump components, and similar applications rely on this grade for controlled material removal before transitioning to finer micron films.

Key Features

• 30.0-micron precisely graded aluminum oxide abrasive for consistent cut rate and finish
• Coated on a 3 mil polyester film backing for dimensional stability during use
• Sheet size of 8.5 inches x 11 inches fits standard lapping fixtures and hand use
• Produces uniform finishes suitable for multi-stage lapping sequences
• Part of the 261X series, available in 0.30, 3.0, 5.0, 9.0, 12.0, and 30.0 micron grades

Compatibility

Designed for use on a variety of substrates including metals, ceramics, glass, and composite materials where controlled micro-finishing is required. Compatible with standard flat-lapping setups and hand-finishing applications.

Installation Notes

Lapping film is installed by technicians and precision finishing professionals working on flat or near-flat surfaces. Secure the sheet firmly to a flat backing plate or lapping fixture before use to prevent slipping and uneven abrasion. Use appropriate personal protective equipment including eye protection when working with abrasive films. Follow facility safety protocols for handling and disposal of abrasive consumables.
