Please note the following safety points and guidelines

  • Ensure that collets are clean and not worn. Worn collets cause vibration which cause breakages
  • Cutters must be inserted in the collet up to 3/4 of the shank length i.e TTP12 x 1.1/4″ (32mm) shank length – ensure 25mm is inserted into collet and secure tightly, do not over tighten
  • Do not use 2′ cut length cutters forshort cut depths i.e TTH122 2″ cut depth to produce 1/2″ depth grooves, select shorter cut length Ref PPH12
  • Allow machine to run at full revs before attempting the cut
  • Even feed rates are required to prevent undue breakages
  • Workpieces must be clamped firmly and safely
  • Always wear protective clothing
  • Any cutter that does not perform satisfactorily or vibrates on cut or causes a high pitch screech when cutting – remove from machine and return to Titman
  • Ensure your machine has a good extraction for operator safety and improvement of cutter performance
  • Do not exceed recommended RPM marked on the cutter shank
