GENERAL TURNING
Steel, cast steel, long chipping malleable iron.
Basic grades
CT5005 (HT) – P05 (P01 — P10)
An uncoated titanium-based cemented carbide – a cermet. This grade is designed to give maximum performance in super-finishing of steel and cast-iron when exceptional surface finish is required.
GC4005 (HC) – P05 (P01 — P15)
A CVD-coated grade with excellent resistance to crater wear and plastic deformation. A very good choice when machining dry, long engagement times or high cutting speeds. For medium to rough steel turning applications. CT5015 (HT) – P10 (P01 — P20)
An uncoated cermet with excellent resistance to built-up-edge and plastic deformation. New formula with improved toughness.
For finishing of low alloy and alloy steels when high surface quality and/or low cutting force are required. fn x ap < 0.35 mm2
GC4015 (HC) – P15 (P01 — P30)
CVD-coated carbide grade for finishing to light roughing of steel and steel castings at high cutting speeds in wet and dry applications. Is able to withstand high temperatures without sacrificing edge security.
GC4025 (HC) – P25 (P10 — P35)
CVD-coated carbide grade for finishing to roughing of steel and steel castings. The combination of a wear resistant coating and a tough substrate allows the grade to handle continuous cuts as well as interrupted cuts at high metal removal rates.
GC1525 (HC) – P15 (P05 — P25)
A PVD coated cermet with very high wear resistance and good edge toughness. For finishing and semi-finishing of low carbon and low alloyed steels. To be used when good surface quality is demanded at medium to high cutting speeds. fn x ap < 0.35 mm2. 10

GC2025 (HC) – P35 (P25 — P40)
CVD-coated carbide grade. Alternative choice for toughness demanding steel applications.
GC235 (HC) – P45 (P30 — P50)
CVD-coated carbide grade for roughing of steel and steel castings under the most unfavourable conditions. The tough substrate
