Technical data

.::　Technical data?　::. 　Warning: Any cutting tool may break or shatter under improper use. Always use of safety glasses and other appropriate safety equipments at all times in the vicinity of their use. 　Cutting tools performance mainly depends on raw material composition, heat-treat process and precision tolerance.Among them material is the most important factor. 　Different country developed its own steel code. 　Following is a data that show major steel codes. 　There are more than 1000 factories of cutting tools in china. Most of them can only supply one or two serial cutting tools. In another word, most of them are middle sized enterprise. No professional sales staff. And quality in China is complex, both poorly hand made tools and CNC professional making tools available. So when choosing partnesr in China, it is top important to find a professional man to communicate. 　With development of China, more and more factories conduct ISO9000 serial quality management system. And some of them import advanced equipments from USA, Germany, Japan, Swiss and other developed countries. So quality is improving. In China, labor cost in relatively cheap and products' price is competitive in world tools market. So huge business opportunities exist in our country. 　 high quality tools steel 1 China USA Japan Germany ISO character HB Temper temperature Usage GB ASTM JIS DIN HB ℃ Carton Steel T7 W1-7 SK7 C70W2 TC70 regular tensile and hardness ≦187 800-820 chisel, hack saw, T8 W1-71/2 SK6 C80W1 TC80 good harness and abrasive ≦187 780-800 route bits, axle, hack saw T8Mn W1-8 SK5 C85W 1 good harness and abrasive ≦187 780-800 hack saw, pouch T9 W1-81/2 SK5 1 TC90 good harness and abrasive ≦192 760-780 wood working cutting tools T10 W1-91/2 SK4 1 TC105 high hardness and abrasive ≦197 760-780 wood working cutting tools T11 W1-101/2 SK3 C105W2 1 high hardness and abrasive ≦207 760-780 hand use taps and die, scrapers, files T12 W1-111/2 SK2 1 TC120 high hardness and abrasive ≦207 760-780 hand use taps and die T13 W1-121/2 SK1 1 TC140 high hardness and abrasive ≦217 760-780 scrapers, files, gauge and so on high speed steel W18Cr4V T1 SKH2 1 1 high hardness and red hardness ≦255 1270-1285 tool bits 、? milling cutters 、? lathe 、? drill bits 、? reamer W6Mo5Cr4V2 M2 SKH51 1 1 high hardness and red hardness ≦255 1210-1230 tool bits 、? milling cutters 、? lathe 、? drill bits 、? reamer W9Mo3Cr4V 1 1 1 1 high hardness and red hardness ≦255 1220-1240 tool bits 、? milling cutters 、? lathe 、? drill bits 、? reamer W6Mo5Cr4V2Al 1 1 1 1 super hardness, its red hardness is better than W6Mo5Cr4V2 ≦269 1230-1240 tool bits,? milling cutters 、? lathe 、? drill bits 、? reamer 、? hob and so on W2Mo9Cr4V2 M7 1 1 1 super red hardness 1 1 tool bits,? milling cutters 、? lathe 、? drill bits 、? reamer 、? hob and so on W6Mo5Cr4V2Co5 M35 1 1 1 best red hardness 1 1 tool bits,? milling cutters 、? lathe 、? drill bits 、? reamer 、? hob and so on W2Mo9Cr4VCo8 M42 1 1 1 best red hardness 1 1 tool bits,? milling cutters 、? lathe 、? drill bits 、? reamer 、? hob and so on
