Offset Internal Rotating Broach Tool Holder




This tool is used to produce hexagonal, square, and other non-round shapes on conventional lathes, mills, and screw machines without the need for a secondary operation. Due to the spindle offset, the turret forces needed to produce a part are minimized. The tool holder spindle is mounted in bearings allowing it to rotate or stop independent of the body without requiring auxiliary driving attachments.

Can be used on B&S, Davenport, and multi-spindle screw machines, as well as turret lathes and CNC machines.
  • Also available with CAT, VDI, CAPTO C6, HSK & Morse Taper Shanks.
