  • Sharpness is improved by polishing the insert edge
  • Reduced tool pressure improves part surface finish
Tooling application
Swiss CNC lathe cut-off operation
Coolant through series of holders (CTDP...OH/OH2/OH3)
Evacuates chips to eliminate chip tangling
Coolant is directed at the cutting edge which greatly improves insert tool life.
