Grade	Granularity(μm)	Characteristics	Application	Microstructure
CDW850	Submicron	Ultra-fine grain structure, strong edge sharpness and edge durability	High 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
CDW002	2μm	High cobalt content, Good electrical machine performance, excellent toughness, Good roughness machining, more convinent for complec tool processing	Mainly 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
CDW005	5μm	Excellent electric spark and machinability, good toughness, wear resistance and edge quality	It 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
CDW010	10μm	Universal PCD Grade, good toughness and high abrasive resisitance	Suit for single tool for rough machining, especially for wood molding, medium and low silicon aluminum alloy parts (such as piston)
CDW025	25μm	High wear resistance and edge quality	Suit for high Silicion Aluminum alloy, MMC, Tungsten carbide and ceramic, graphite,wear resistant parts,  mainly used in wood Wood finishing insert and saws
CDW302	2~30μm	Mixed 2μm and 25μm,good wear resistance and edge quality and edges strength	It mainly used for machining MMC, high Silicion Aluminum calloy, high strength cast iron and other application.
