Application range by shank type
Application range by shank type Echaintool boring bar manufacturer

  • Deep hole drilling of L/D = 6 with work diameters of 32mm and above.
  • Negative inserts reduce unit price per corner.
  • Combinable with a wide range of chipbreakers for use in everything from rough cutting to finishing.
Cutting Speed Vc=20~200m/min, Depth of cut ap=0.1~2.0mm, Feed Rate f=0.1~0.3mm/rev
*Actual amount of overhang may differ according to work material, tool shape, and machining conditions.
