Technical information Inserts
Insert grades
Cemented carbide is an alloy of tungsten carbide (WC) and cobalt (Co). Cubic carbides like tantalum carbide (TaC), titanium carbide (TiC) and niobium carbide (NbC) can also be added. Tungsten carbide is the main component and gives the hardness. Cobalt is the binder phase and gives the toughness. Cubic carbides are added in order to affect properties like hot hardness, deformation resistance and chemical wear resistance.
Most modern grades are coated with either CVD (Chemical Vapour Deposition) or PVD (Physical Vapour Deposition) technique. The coating improves the wear resistance of the grade. CVD-coated grades are suitable for wear resistance in demanding applications with high feed rates and intermediate to high cutting speed. PVD-coated grades are recommended for applications with low feed rate where high edge toughness is required. PVD-coated grades are suitable for applications with low to intermediate cutting speed.
H15 and H25 = uncoated CS300 and CW100 = ceramic
The black oval circle areas in the chart indicate an inserts main ISO application groups. The white oval circle area in the chart indicate an inserts other complementary ISO application groups.
For TGP45 use ISO application area for MP2501 For CP500 and CP600 use ISO application area respectively for F30M and F40M
