SP35 35 Ton Hydraulic Punch, Enerpac

 SP35 Hydraulic Punch - Enerpac Catalog

When you're working in the field or the shop and need to make quick, clean, and accurate holes in metal, the Enerpac SP35 hydraulic punch delivers where it counts. Built for reliability in even the most demanding environments, this compact hydraulic punch combines power, portability, and precision — making it an essential tool for heavy-duty industrial maintenance teams, steel fabricators, construction crews, and mobile repair units.

This isn't your average punching tool. The SP35 brings Enerpac's trusted engineering to a portable design that can punch holes through up to 0.5 inches (12.7 mm) of mild steel with minimal effort — all while maintaining alignment, reducing distortion, and minimizing downtime.

What Makes the Enerpac SP35 Unique?

The SP35 stands out thanks to its 30 tons of punching force in a compact 45.3 lb package. Whether you're mounting electrical panels, modifying structural components, or fabricating brackets in the field, this tool gives you power without bulk.

With a punching capacity of 0.59" diameter in 0.5" thick steel, this unit eliminates the need for drilling, saving hours on job sites where time is money and accuracy is non-negotiable.

Built for Real-World Demands

Whether you're working vertically on an I-beam or flat on a bench, the Enerpac SP35 performs. Its rugged steel construction and double-acting hydraulic cylinder are engineered for both horizontal and vertical use — making it just as suitable for in-shop fabrication as it is for mobile field service operations.

Need to punch a hole in a remote substation panel or modify truck frame brackets out in the yard? Just hook it up to a compatible 10,000 psi hydraulic pump, and you're ready to go.

And when the job's done? The punch and die can be swapped easily, and the entire unit can be cleaned and stored without hassle.
