CoroTurn® 300
Effective and high-quality turning
Instructions
Insert change
Insert is changed in five easy steps where a clamping solution with lever makes the insert self-locking into the tip seat and fixed location points (iLock™) ensures rigidity and accuracy. Use a torque of 4.5 Nm.
Coolant connection on QS™ shanks
There are four ways to connect the coolant: using adaptor (first choice), using rear tube connection, with front and underneath connection or with 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 set-up.
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 both can improve performance and solve typical turning challenges.
