Rotary Broach Holders & Set-Up Plugs

Adjustable rotary broach holders are essential for mounting rotary broaches onto compatible machinery, including lathes, milling machines, and machining centers. Featuring an internal spindle, these holders synchronize the broach's rotation with the workpiece's speed on turning machines. By maintaining the broach's centerline at a precise 1° angle to the workpiece's centerline, they induce a controlled wobble. This motion generates a shearing action, enabling efficient material removal as the broach advances into the workpiece.

Set-up plugs for rotary broach holders are essential for precision broaching operations. They create a precise indentation on the workpiece, ensuring the rotary broach remains perfectly centered during the initial cutting phase. These plugs are mounted on the machine's tool holder prior to the broaching process, where they mark the exact location for the broach with a shallow, circular guide. Once the guide is set, the plug is replaced with the rotary broach to commence the broaching operation, guaranteeing accuracy and efficiency.
