BT40 – 45 Degree Shank Pull Stud

Description

The Schmidt TE07803 is a BT40 45° pull stud (also called a retention knob) for BT40 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 45° 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 (45° standard on most BT40 machines; confirm from machine documentation) before ordering. Replace pull studs at the first sign of thread wear, deformation, or ATC engagement issues.
