CoroTurn® 300
Effective and high-quality turning
Instructions
Insert change
The insert is changed in five easy steps. A clamping solution with lever makes the insert self-locking in the tip seat, and fixed location points (iLock™) ensure rigidity and accuracy. Use a torque of 4.5 Nm.
Coolant connection on QS™ shanks
There are four ways to connect the coolant: using an adapter (first choice), using the rear tube connection, with front and underneath connection, or with the rear tube connection with a QS stop.
Coolant supply
By plugging the coolant holes, you can choose between using just over or under coolant, or both, which is the standard setup.
Application tips
Over- and under- coolant - When to use what?
CoroTurn® 300 features over- and under- coolant. Find out how to apply it correctly and how this can both improve performance and solve typical turning challenges
