3M 7010360185 Diamond Lapping Film 3.0 Micron 3x6 in

Product Description

The 3M 7010360185 is a diamond lapping film sheet designed for precision surface finishing on extremely hard materials. Precisely graded diamond abrasive particles are coated onto a dimensionally stable polyester film substrate, delivering a consistent, repeatable surface finish with each pass. At 3.0 micron particle size, this sheet produces a fine finish suitable for critical tolerances. It is used by machinists, optical technicians, tool-and-die makers, and field technicians who need controlled, measurable material removal on hard substrates. Each sheet measures 3 inches x 6 inches and is sold individually.

This lapping film is suited for finishing carbide, ceramics, hardened steel, optical glass, fiber optic connectors, and other hard or brittle materials where conventional abrasives leave unacceptable surface variation. Typical applications include lapping precision mating surfaces, polishing fiber optic ferrules, and final-stage finishing on cutting tools or gauging surfaces. The 3.0 micron grade falls within the available range of 0.10 to 30.0 micron, positioning it as a fine-finishing step in a multi-stage lapping sequence.

Key Features

• Precisely graded 3.0 micron diamond particles for controlled, repeatable material removal
• Polyester film backing provides dimensional stability during hand lapping and machine lapping operations
• Consistent abrasive coating delivers uniform finish across the full sheet surface
• Sheet size of 3 inches x 6 inches fits standard lapping fixtures and hand-held backing plates
• Suitable for extremely hard materials including carbide, ceramics, and hardened metals

Compatibility

Designed as an OEM-style lapping consumable for use with flat lapping plates, backing films, or hand-lapping fixtures that accept sheet-format abrasive film.

Installation Notes

Lapping film is typically applied by precision machinists, optical technicians, or tool-and-die professionals using flat glass plates, lapping fixtures, or backing pads. Ensure the work surface and lapping plate are clean and free of contamination before use to avoid scratching from embedded debris. Apply consistent, controlled pressure during lapping strokes to maintain a uniform finish. Dispose of worn sheets before abrasive performance degrades to avoid inconsistent material removal.
