Modular system of adapters and cutting heads for internal turning, grooving, threading, boring, and multi-task machining, for hole diameters down to 20 mm. For machining in turning centers, lathes, and multi-task machines.
Choose a suitable adapter

For the best performance of your CoroTurn® SL tool, always choose the shortest possible overhang.
Select a suitable cutting head
Choose a cutting head that fits your application (recommendations below). Consider the SL70 interface for profiling or pocketing large components or difficult-to-reach features.
Always use the right torque
Use the correct tightening torque when mounting the cutting head.
