Diamond Lapping Film – 8-Inch Discs (Ø203mm)

Overview

Diamond Lapping Film Discs (8-inch / Ø203mm) are high-precision abrasive films engineered for consistent, controlled material removal and ultra-fine surface finishing. These discs feature micron-graded diamond particles uniformly coated on a durable polyester backing, delivering exceptional flatness, long life, and repeatable performance in both manual and machine-based polishing processes.

Widely used in fiber optics, electronic components, semiconductors, metal polishing, and industrial lab sample prep, XYT’s 8-inch diamond discs are ideal for flat surface lapping, connector polishing, wafer planarization, and more.
