CNC Machine Carbide inserts DCMT11T308 Internal Turning inserts


A carbide insert is a cutting tip used on a larger tipped tool whose shank is made of another material, usually carbon steel. This offers the benefits of a carbide cutting interface without the high cost and brittleness of making the entire tool out of carbide.


  • Choose between the following options to find the best grade and chipbreaker for your turning operations
  • Workpiece material:P steel;M stainless steel;K cast iron
  • Workpiece condition:Continuous Cutting;Light Interrupted Cutting;Heavy Interrupted Cutting
  • Roughing or Finishing:Finishing or Precision Cutting;Medium Cutting;Medium to Heavy Cutting.
The Chipbreaker Instruction of Carbide Indexable CNC Turning Inserts
DFChip-breaker with special angle design can make cut easy,control chip and get good surface quality.
DMWidely used chip-breaker is used for semi-finishing and finishing machining steel and stainless steel.
DRSpecial chip-breaker with high toughness cutting edge can reduce cutting force.
PMWith stronger cutting edge,it is better for intermittent cutting than -DM,with widely cutting zone of P type material.
HFWith sharp cutting edge,used for finishing machining inner hole,fine finishing surface can be got with small feed rate.
HMWith sharp wave cutting edge to reduce cutting force,it is the first choice for semi-finishing machining of inner holes and can make chip flow smoothly.
HRWith tough cutting edge,used for roughing/machining of inner hole and intermittent machining workpiece with irregular surface.
LHMainly recommended for finish turning,Typical parts: Ordinary aluminum parts.
