Offset Internal Rotating Broach Tool

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.

FOR CNC LATHES TOO!

HAS KNOCK OUT HOLE THRU

SPINDLE FOR BROKEN REMOVAL.
