Grades Characteristics Applications
1 High abrasion resistance - Wear resistance - Excellent edge quality and retention - Produces fine surface finishes Perlitic grey cast iron-sintered alloys - Tool and die steels Hard facing alloys - Finish of Ni and Co base super alloys - Turning of sintered carbide (>16% cobalt content)
2 Hard turning continous cut - High material removal - Good surface finish - Good tool life Hard alloys steels - Super alloys
8 Hard turning continous cut - High material removal - Very good surface finish - Improve tool life Hardened steel >45 HRC - Hardened tool and die steels - Hardened high carbon steel - Hard turning countinous and slight interruped cuts
32 Excellent impact resistance - Good chemical stability Continous to interrupted cuts - Cast iron Powder metal alloys - Tool steel machining
43 Improve microstrutural homogeneity - Consistent and repeatable performance Cylinder line boring Gear turning - Milling of hardened steel - Turning of sintered carbide >16% Co
30 Excellent abrasion resistance - Good chemical stability Excellent in machining of ductile iron - Powder metal application where carbide is lower - Continous to lightly interruped cuts
44 Excellent chimical stability - Impact resistant - Provide excellent surface finish Sintered metals with high alloy content - Exhaust and intake valve machining - Countinous cuts
45 Superior chimical wear resistance - Excellent surface finish High speed continous turning in finishing - Case hardened steels - Typical speed 220m/mn or greater
46 Excellent chimical and abrasion wear resistance - Excellent surface finish - Exceptionally long tool life - Improve impact resistance to type 45 Continous to slightly interrupted custs - Case of hardened steels - Typical speed 180 m/mn or greater
47 Excellent balance of flank and crater wear resistance - Good chipping resistance - Suitable for both wet and dry conditions Continous to mild interrupted turning - Hardened steel and cold work tool steels - Typical speed 100-175 m/mn
48 Superior edge toughness - Good flank and crater wear resistance - Suitable for both roughing and finishing cuts Countinous to medium interruption cut - Hardened steels - Powder metal machining - Ideal for both milling and turning - Typical speed 140-220m/mn
49 Superior edge toughness - Suitable for both roughing and finishing cuts Mild to heavy interruption - Valve seat machining - Typical speed 80-150 m/mn
