CoroTurn® SL
Modular system of adaptors 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 adaptor
There are several adaptive items and tool holding options to choose from. If working with long overhangs or want to increase productivity, consider a Silent Tools™ damped boring bar.
Choose shortest possible overhang
For best performance of your CoroTurn SL tool, always choose the shortest possible overhang.
Select suitable cutting head
Choose cutting head that fits your application (recommendations below). Consider SL70 interface for profiling or pocketing of large components or difficult-to-reach features.
Always use the right torque
Use correct tightening torque when mounting the cutting head.
Application tips
Tips for internal grooving
Long overhangs and poor chip evacuation are two of the challenges with internal grooving. Long overhangs can cause problems with both deflection and vibration while vibrations and poor chip evacuation can cause insert breakages
