BT30 90° Pull Stud

Description

The Schmidt TE07812 is a BT30 90° pull stud (also called a retention knob) for BT30 taper tool holders. Pull studs thread into the top of the tool holder and interface with the automatic tool changer (ATC) pull mechanism in the machine spindle. The 90° angle is the stud flange contact angle — must match the machine’s ATC pull stud specification exactly. Using the wrong angle pull stud will prevent the ATC from properly gripping or releasing the tool holder. Verify the machine spindle pull stud specification (90° standard on most BT30 machines; confirm from machine documentation) before ordering. Replace pull studs at the first sign of thread wear, deformation, or ATC engagement issues.
