Precision Lapping Film Products | Diamond Polishing Film Disc and Sheet

Precision lapping film is a high-performance abrasive material designed for flat surface finishing, geometric control, and ultra-smooth polishing. Among all abrasives, diamond polishing film is the ideal choice for hard-to-process materials such as ceramics, glass, tungsten carbide, sapphire, and fiber optic ferrules.

We offer a full line of diamond lapping film discs and sheets with consistent abrasive quality, tight grit control, and long service life — essential for demanding industries like fiber optics, semiconductors, optics, and precision tooling.
