3M Aluminum Oxide Lapping Film, 4 in. Dia., 2 Micron, 6192B-254X-2D4H

Overview

The 3M Lapping Film 6192B-254X-2D4H is a 4-inch diameter aluminum oxide abrasive disc engineered for precision microfinishing and polishing applications. At 2 micron grade, it delivers fine, consistent finishes on flat and cylindrical surfaces — ideal for fiber optic connector end-face polishing, hard disk drive head finishing, and the processing of delicate electronic components. Backed by a 3 mil polyester film substrate, it provides dimensional stability and uniform mineral distribution for repeatable results in critical finishing operations.

Features

• Aluminum oxide mineral on a durable 3 mil polyester film backing
• 2 micron grade for ultra-fine surface finishing and tight tolerance work
• 4-inch diameter disc — compatible with standard lapping fixtures and polishing machines
• Delivers consistent, predictable, repeatable finishes in fewer passes
• Cleaner alternative to diamond slurries or honing stones — no messy residue
• Engineered for use with fiber optic connectors and hard disc drive lube buffers
• Suitable for brittle materials including glass, sapphire, SiC, zirconia, and hardened metals
• Reduces rejects and rework by eliminating traverse and chatter marks
