(Note)
  • Set the finishing allowance on a diameter at approx. 0.1mm when using a full form insert.
  • Please note the cutting depth and the number of passes when a nose radius of a partial form insert or of an internal threading insert is small to prevent damage to the insert nose.
  • Please set the cutting depth sufficiently deep enough on materials such as hardened steel or austenitic stainless steel to help prevent premature wear and chipping caused by the outer layer of the material.
