Hassay Savage Rotary Broach Holders

Broaching A Rotating Workpiece

• In a turning or screw machine, the holder is mounted stationary while its internal live spindle and the broach rotates after contact with the rotating workpiece.
• At the appropriate feed, the workpiece is “sheared” by the pressure of the broach through a wobbling type action producing the polygon shape desired.

Broaching A Stationary Workpiece

• In a milling or drilling machine, the holder is mounted into and rotates with the machine spindle while its internal live spindle along with the broach remains stationary upon contact with the stationary workpiece.
• While the machine spindle is rotating, the broach’s pressure shears the polygon shape into the workpiece (wobbling type action).
• Use on any type of CNC or manual turning, milling, drilling or screw machine.

• While the machine spindle is rotating, the broach’s pressure shears the polygon shape into the workpiece (wobbling type action).
• The holder has an internal live spindle, which holds the end cutting broach tool.
• The centerline of the cutting tool is offset at 1 from the centerline of the workpiece.
• This offset causes the broach to wobble creating a shearing effect as the broach is advanced into the workpiece or vise versa.
