CoroTurn® 107

Maximize quality with fixed insert indexes

Inserts and tool holders with rail interface ensure mounting security and offer secure machining for profiling and pocketing applications. When the insert is indexed the same way every time you can increase productivity and achieve higher quality.

Unobstructed chip flow

Screw clamp design of CoroTurn® 107 ensures stability and unobstructed chip flow while turning. It is easy to handle, clean and maintain.


Excellent chip control

​Tool holders are equipped with nozzles that direct precision coolant right at the insert edge to boost process security and provide excellent chip control.

CoroTurn® 107 with rail interface

Use the round inserts and tool holders with rail interface for secure machining of your profiling and pocketing applications. The rail interface locks the rotation of the insert, minimizing unwanted stops from insert or screw breakage. Tool holders are available with over and under coolant for good chip control and high process security.

To boost your productivity in HRSA materials, use the screw-mounted CBN platform, with up to 12 insert indexes.
