Screw clamping
Clamping of CoroCut 1 and 2-edge inserts
The insert clamping system has been designed to counteract high axial forces from both
sides. For the smaller inserts (insert seats D–G) a V-profile clamping is used, but for larger
inserts (insert seats H–L) the unique rail design adds superior stability to the insert clamping.
The rail system should be first choice for profiling and turning applications (generating side
forces) giving increased cutting data and highest stability.

The force holding the insert is generated by two different designs.
1. Screw clamping.
2. Spring clamping.
Spring clamping
Spring clamping
Parting blades have deep accessibility in narrow areas due to spring clamping. This allows for
quick and easy clamping and loosening in the same operation, due to an excentric key.
See the pictures above.
Screw clamping
All our solid toolholders/bars have integrated screw clamping. This gives very stable and
secure clamping of the insert and is recommended for applications where large cutting forces
arise (together with rail insert seat). This is particularly important when combined with small
cutting depths as in longitudinal turning, profiling and face grooving.
