Polycrystalline diamond has multiple cutting edges, good self-sharpening property, high grinding efficiency, which brings uniform mirror surface with few deep scratches, better than single crystal diamond on heterogeneous hard materials.

 Application: Mirror polishing & sharpening for knives, cutting blades, tungsten carbide, hard alloy, ceramic, sapphire and other superhard workpieces.

Advantage: Stick form, convenient to apply on polishing lap / leather strop; stable grain distribution, consistent polishing result.

 Custom service: Different particle sizes (0.25μm~60μm), different diamond concentration and dimensions can be customized.
