6 in Diamond Lapping Film Discs, 10-Pack, PSA-Backed Precision Abrasive

The 6 in Diamond Lapping Film Discs (10-Pack, PSA-Backed) feature micron-graded monocrystalline diamond particles uniformly resin-bonded onto a heavy-duty polyester film, providing exceptional cutting speed and flatness on ultra-hard materials.

Key Features

• Precision Graded Synthetic Diamond: High-purity micro-diamond particles deliver sharp, aggressive, and uniform micro-cutting on materials up to Mohs hardness 9+ (sapphire, ruby, and ceramic).
• Pressure-Sensitive Adhesive (PSA) Backing: Peel-and-stick backing adheres securely to 6-inch master laps, flat platens, and metallurgical discs without slippage or wrinkling.
• High-Strength 3 mil Mylar Backing: Heavy-duty polyester base maintains true flatness under pressure, preventing facet rounding and edge rollover.
• Consistent 10-Pack: Multi-disc package designed for high-efficiency facet prep, metallographic polishing, and industrial lab production.

Recommended Applications

• Precision gemstone faceting and flat pre-polishing on corundum (sapphire and ruby), spinel, chrysoberyl, and cubic zirconia.
• Metallographic preparation of cemented carbides, technical ceramics, and hardened alloy steels.
• Fiber optic connector polishing (ceramic ferrule geometry and glass-core planarization).
• Precision tool, knife, and plane iron stropping and sharpening.

Operating Guidelines

• Ensure master lap platen is flat, clean, and free of dust or oils before sticking the disc.
• Operate wet with water or light diamond lapping lubricant to flush swarf and extend disc life.
• Maintain light, even contact pressure across the 6-inch surface to achieve optimum scratch patterns.
