High performance in tough operations
Grade GC1145 adds performance to tough parting and grooving applications. With high edge toughness and superior wear resistance, tool life or cutting speed can be gained in difficult parting operations in stainless steels. Up to 300% tool life has been experienced in customer tests against competitor products.
Secure enough to handle
narrower parting widths
GC1145 has improved edge line security. The cutting edge resists chipping and stays intact for longer time in cut. With GC1145, it is safe to go down an insert width, when cutting off and economize material. |
|
A typical application for GC1145 is cutting off stainless steel bars. When the speed drops, in the centre of the bar, GC1145 resists chipping thanks to its toughness.
In interrupted cuts, GC1145 handles higher cutting speeds than comparable grades, without losing tool life.
Grade description
GC1145 combines submicron cemented carbide with a strengthening PVD oxide coating. The result is a grade which combines high edge toughness with wear resistance. |

When to choose GC1145
- Parting and grooving in ISO P, M and S
- Cutting off in stainless steels
- For interrupted cuts
- When rotational speed is limited and cutting speed is low
