Grades for parting and grooving
Heat resistant and super alloys
Basic grades
Complementary grades
B
GC1105 (HC) - S15 (S10-S20)
A PVD-coated carbide grade with high hot hardness and good resistance against
plastic deformation giving even flank wear and outstanding performance. First choice
for grooving and profiling.
CB7015 (BN) − S15 (S05-S25)
A cubic boron nitride composite suited for heat resistant super alloys. This grade
allows sharp edges optimized for surface finish and low depht of cuts.
GC1145 (HC) − S40 (S30-S40)
A PVD-coated carbide grade. First choice for parting off when demand on secure edge
line is needed. To be used at low cutting speeds
GC1115 (HC) − S20 (S10-S25)
A PVD-coated carbide grade with high hardness and combined with superoir edge line
security. Good resistance against notch makes the grade suitable to use in difficult
materials.
C
S05F (HC) - S10 (S05-S15)
A CVD-coated carbide grade. To be used both for high speed finishing and roughing
profiling operations.
GC1135 (HC) − S25 (S10-S35)
A PVD-coated carbide grade for toughness demanding operations. To be used at low
cutting speeds.
D
GC1125 (HC) - S25 (S15-S35)
A PVD-coated grade for toughness demanding operations, recommended for
interrupted cuts. To be used at low cutting speeds
GC2135 (HC) – S30 (S20–S40)
A CVD-coated carbide grade for toughness demanding operations such as cut-off to
centre and interrupted cuts.
E
H13A (HW) – S15 (S10-S30)
Uncoated carbide grade. Combines good abrasive wear resistance and toughness for
parting and grooving. First choice in titanium.
CC670 (CA) – S10 (S05-S25)
A whisker reinforced aluminium oxide based ceramic with excellent bulk toughness.
To be used under favourable conditions.
F
GC1025 (HC) - S25 (S15-S35)
A PVD-coated grade for toughness demanding operations. Recommended for Small
Part Machining. To be used at low cutting speeds.
