Tipped with Micro 100 high rupture strength & shock resistant carbide


  • Designed to be used for machining a variety of different sized holes.
  • General purpose carbide tipped tools for various radius turning operations.
  • Right hand cutting applications.
  • May also be employed for milling, boring or other operations.
  • Used in a toolholder for lathe boring applications or they may be mounted in a boring head for boring in a milling machine.
  • Can also be used in other machines as well.
  • Well suited for interrupted cutting.


  • The basic design of these boring bars incorporates a cylindrical body where the tool is the same size from one end to the other, allowing these bars to have considerable strength and rigidity while minimizing vibration, throughout a range of speeds and feeds.
  • Tipped with a proprietary carbide from Micro 100®, offering high rupture strength and shock resistance and resists chipping or breaking very well, under normal machining conditions.
