3M 7000118193 Diamond Lapping Film 30.0 Micron Sheet

Product Description

The 3M 7000118193 is a diamond lapping film sheet engineered for precision surface finishing on extremely hard materials. Precisely graded diamond abrasive particles are coated onto a dimensionally stable polyester film backing, delivering a consistent, repeatable finish cut after cut. At 30.0 micron particle size, this sheet is suited for aggressive stock removal on hard substrates before progressing to finer grading steps. Each sheet measures 6 inches x 6 inches, making it practical for both hand lapping and fixture-mounted finishing operations. Technicians working with carbide tooling, ceramics, optical components, and precision metal surfaces rely on this product where surface finish tolerances are critical.

This lapping film is used in applications requiring controlled material removal on hard surfaces that conventional abrasive films cannot effectively cut. Typical use cases include lapping fiber optic connectors, precision tooling, ceramic components, and hardened metal parts in manufacturing, maintenance, and repair environments. The 30.0 micron grade is generally employed as an early-stage finishing step in a multi-step lapping sequence. It is sold individually by the sheet, with a minimum order quantity of 25 sheets per the manufacturer unit of measure.

Key Features

• Precisely graded 30.0 micron diamond abrasive for controlled, repeatable stock removal
• Diamond particles bonded to a polyester film backing for dimensional stability during use
• 6 inches x 6 inches sheet size suits hand lapping and fixture applications
• Effective on extremely hard materials including carbide, ceramics, and hardened metals
• Part of a broader diamond lapping film range spanning 0.10 to 30.0 micron grades

Compatibility

Designed for use as a precision lapping sheet on hard substrates including carbide, ceramics, optical components, and hardened metals where consistent surface finish is required.

Installation Notes

Diamond lapping film is typically used by precision machinists, tool and die technicians, and fiber optic technicians performing controlled surface finishing. Secure the sheet to a flat lapping plate or backing fixture before use to maintain uniform contact pressure across the workpiece. Avoid folding or creasing the film, as this can cause inconsistent abrasive contact and damage the coating. Use appropriate personal protective equipment when handling fine abrasive materials.
