Greenlee 7212SP23 Round Draw Stud Speed Punch

Product Description

The GREENLEE 7212SP23 is a round draw stud designed as a replacement component for use with the Greenlee SPEED PUNCH hydraulic punch system. The draw stud is the central threaded rod that pulls the punch through the workpiece during knockout operations. It bears the full load of the punch cycle, making material integrity and thread precision critical to safe, consistent hole-cutting performance. This part is installed by licensed electricians and field technicians who maintain or repair hydraulic knockout tooling on the job site or in a shop setting.

This draw stud is intended for use with Greenlee SPEED PUNCH System components. It is suited to electrical trade applications where hydraulic knockout punches are used to produce clean, round conduit openings in enclosures, panels, and junction boxes. The round profile matches the standard geometry required by SPEED PUNCH tooling and is packaged as a single-unit replacement to restore a worn or damaged assembly to full working condition.

Key Features

• Round profile sized for direct compatibility with Greenlee SPEED PUNCH System components
• Replacement draw stud restores hydraulic knockout tool to operational condition
• Single-unit packaging supports targeted component-level repair without replacing full tooling
• Designed to handle the axial load generated during hydraulic punch-through cycles

Compatibility

Designed for use with Greenlee SPEED PUNCH System components as specified by the manufacturer. Verify the draw stud thread specification and diameter against your existing SPEED PUNCH tooling before installation.

Installation Notes

Installation is typically performed by a licensed electrician or tool technician familiar with hydraulic knockout equipment. Before replacing the draw stud, relieve all hydraulic pressure from the punch system and inspect the punch, die, and ram for wear. Thread engagement must be complete and secure before operating the tool. Follow the manufacturer service documentation and applicable NFPA 70 (NEC) safety practices when working near energized panels.
