101.6mm x 10M Diamond Lapping Film Rolls – Precision Sandpaper for Metal, Glass, Ceramic & Gemstone

The 101.6mm x 10M Diamond Lapping Film Roll (4 in x 32.8 ft) is an industrial continuous-feed micro-abrasive roll featuring tightly graded diamond crystals electro-bonded onto a heavy-duty polyester film backing.

Key Features

• Continuous Roll Format (101.6mm / 4" Width x 10M Length): Convenient continuous format allows custom cutting into strips, discs, sheets, or spiral roller wrapping for specialized micro-finishing machines.
• Precision Graded Diamond Crystals: Consistent micro-grit diamond grains deliver rapid stock removal and uniform scratch patterns across hard materials up to Mohs hardness 9+.
• Heavy-Duty Tear-Resistant Mylar Film: High tensile-strength polyester backing resists stretching, tearing, and curling under wet and dry micro-abrasion.
• Multi-Industry Versatility: Outperforms conventional abrasive papers by up to 50 times, maintaining consistent cutting rates throughout its working life.

Recommended Applications

• Metallographic sample preparation and micro-structure polishing in laboratory settings.
• Roll superfinishing and precision cylinder grinding on printing, textile, and industrial rollers.
• Hard gemstone facet polishing and pre-polishing on corundum (sapphire, ruby), chrysoberyl, and quartz.
• Ceramic, tungsten carbide, and thermal spray coating surface planarization.

Operating Guidelines

• Cut to required length using sharp shears or precision guillotine cutters.
• Operate wet with clean water or specialized lapping fluid for optimal cooling and debris evacuation.
• Apply light to moderate contact pressure; allow diamond sharpness to do the work.
