ISO application area

 

Recommendations

​Inserts options
  • Inserts for higher security and heavier cuts

  • Inserts with sharper edges for higher precision suitable for semi-finishing
Radius limitations
During full slotting, the bottom profile generated will not form a perfect radius. This form error, which appears at the centre cutting zone of the tool, can be minimized by using the E-tolerance inserts.
