6 in Aluminum Oxide Precision Lapping Film Discs, Multi-Micron Set for Optics & Lapidary

The 6 in Aluminum Oxide Precision Lapping Film Discs are engineered for consistent, tightly calibrated micro-abrasion across precision lapidary faceting, fiber optic polishing, and metallographic material preparation.

Key Features

• Graded Aluminum Oxide Minerals: Tightly controlled micro-grit particle distribution guarantees predictable surface finishes and uniform scratch patterns.
• Durable Polyester Backing: 3 mil high-strength Mylar film backing provides flat, tear-resistant performance under dry and wet operating conditions.
• 6-Inch Standard Diameter: Perfectly sized for 6-inch faceting master laps, flat lap discs, and metallurgical platen machines.
• Multi-Step Grading: Ideal for progressive pre-polishing and fine finishing steps before final cerium oxide or diamond polish.

Recommended Applications

• Gemstone facet pre-polishing and cabochon finishing (quartz, beryl, tourmaline, and feldspar).
• Fiber optic connector termination and telecommunication polishing routines.
• Precision metallurgy, failure analysis sample preparation, and geological thin sectioning.
• Chisel, plane iron, and precision cutting tool stropping and sharpening.

Operating Guidelines

• Place on a smooth, clean master lap or glass backing plate with light surface water tension or spray adhesive.
• Operate wet with clean water or specialized lapping fluid for optimal heat control and slurry evacuation.
• Apply light to moderate, uniform pressure to prevent particle stripping.
