55mm x 20M Diamond Lapping Film Roll – Precision Abrasive for Metal, Glass, Ceramic & Gemstone

Diamond Lapping Film Rolls are engineered for continuous, ultra-precise surface finishing, delivering exceptional flatness and smoothness for demanding applications in industries such as electronics, optics, materials science, and advanced manufacturing. These precision rolls combine premium diamond abrasives with high-strength polyester film, offering unmatched consistency on hard, brittle, or delicate materials.

Key Features

Premium Diamond Abrasives

• Uniform Particle Distribution: Resin-bonded, tightly graded diamond particles (0.1–30µm grit) ensure consistent material removal and scratch-free finishes.

• Continuous Roll Format: 55mm width by 20M length format is ideal for automatic cassette lapping machines, continuous polishing systems, and custom shop dispensing.

• Long Lifespan: Significantly longer working life compared to conventional abrasives.

Wet/Dry Compatibility

• Optimized for both wet (coolant-assisted) and dry workflows, reducing heat buildup and enhancing finish quality.

Material Versatility

• Effective on carbides, ceramics, fiber optics, semiconductor wafers, microelectronics, high-hardness metals, and gemstones.
