1. PCD Grade and Application

CDW850SubmicronUltra-fine grain structure, strong edge sharpness and edge durabilityHigh precision machining, mirror surface machining, suite for aluminum alloy that required high on the chipping performance, mainly used for machining Ti alloy and other composites
CDW0022μmHigh cobalt content, Good electrical machine performance, excellent toughness, Good roughness machining, more convinent for complec tool processingMainly used for engrave milling cutter and thread cutting tool, and also cutting tools for wear-resistant parts, used in woodworking saws, particleboard and the tools for machining silicon aluminum alloy
CDW0055μmExcellent electric spark and machinability, good toughness, wear resistance and edge qualityIt suits for good surface quality processing, mainly used for machining PMMA, Silicion alloy and metal  cell phone shell outlin and used in the wood cutting tools, saws industry
CDW01010μmUniversal PCD Grade, good toughness and high abrasive resisitanceSuit for single tool for rough machining, especially for wood molding, medium and low silicon aluminum alloy parts (such as piston)
CDW02525μmHigh wear resistance and edge qualitySuit for high Silicion Aluminum alloy, MMC, Tungsten carbide and ceramic, graphite,wear resistant parts,  mainly used in wood Wood finishing insert and saws
CDW3022~30μmMixed 2μm and 25μm,good wear resistance and edge quality and edges strengthIt mainly used for machining MMC, high Silicion Aluminum calloy, high strength cast iron and other application.
