OFFSET INTERNAL ROTATING BROACH TOOL HOLDER

Internal Rotating Broach Holder • This tool is used to produce hexagon, square and other irregular internal shapes in the workpiece as it is rotating in the spindle of the machine.

• Minimal turret driving force is required due to the spindle offset which distributes the load of the cut.

• The tool holder spindle, which is mounted in ball bearings, rotates freely with the workpiece and does not require auxiliary driving attachments.

• Fine adjusting screws are provided for accurate aligning of the broach with the pre-drilled hole in the workpiece.

• 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.
