Applications
This turning tool unfolds its full potential in the machining of various steel materials. The insert is primarily designed for continuous cuts and is excellently suited for medium machining as well as fine finishing tasks. By providing controlled chip formation, it supports reliable production processes for turned parts that demand high dimensional accuracy and exceptional surface finish.
Special features
The next-generation CVD-coated P15 carbide protects the cutting edge against premature wear. The well-thought-out PF geometry proves to be a true problem-solver, particularly in softer or tough steel alloys. This combination of toughness and tailored chip evacuation contributes to positively influencing tool life and reducing machine downtimes.
