Abstract
A stud punch includes a housing, a motor positioned within the housing, and a planetary gear train that receives torque from the motor. The stud punch also includes a punch movable between a retracted position and an extended position, and a scotch-yoke mechanism coupled between the planetary gear train and the punch. The scotch-yoke mechanism is configured to convert torque received from the planetary gear train to a reciprocating linear force, causing the punch to move between the retracted position and the extended position.

A stud punch comprising:
- a housing;
- a motor positioned within the housing;
- a planetary gear train that receives torque from the motor;
- a punch movable between a retracted position and an extended position;
- and
- a scotch-yoke mechanism coupled between the planetary gear train and the punch,
- wherein the scotch-yoke mechanism is configured to convert torque received from the planetary gear train to a reciprocating linear force, causing the punch to move between the retracted position and the extended position.
A stud punch comprising:
- a housing;
- and
- a stud punch head coupled to the housing, the stud punch head including
- a head housing,
- a punch supported by the head housing,
- an arm extending from the head housing and defining an aperture therein, and
- a die that is removably received within the aperture.
A stud punch configured to punch through a metal stud to form a hole, the stud punch comprising:
- a housing;
- and
- a stud punch head coupled to the housing, the stud punch head including
- a head housing that defines an opening,
- a punch supported by the head housing and movable between a retracted position located within the opening and an extended position extending outward from the opening, and
- a guard movably supported by the head housing and configured to shield the opening as the punch moves from the retracted position to the extended position.
