3 Inch Metal Hole Punch

Hydraulic ironworkers and single-end hydraulic punches are the primary tools used to punch holes in metal. These machines use a punch and die set under high tonnage force (50-225 tons) to shear clean holes through mild steel plate, angle, and structural shapes without heat-affected zones.

Required tonnage depends on plate thickness and hole diameter; larger holes and thicker material demand higher tonnage. Piranha's ironworker line spans 50 to 225 tons, and dual-operator models like the BII Series (66-225 tons) are commonly specified for oversized hole punching in heavier gauge plate.

An ironworker combines punching, shearing, and notching stations in one machine, ideal for shops needing versatility. A single-end punch, like the SEP-120, is dedicated solely to punching with a deep throat depth (21.5") for oversize holes and specialty tooling, offering a cost-effective standalone solution.

Punching a 3 inch hole typically requires an oversize punch and die set rated for the material thickness, along with sufficient machine tonnage and throat depth to accommodate the tool. Piranha machines feature quick-change dovetail tooling systems that simplify swapping to oversize punch sets.

Piranha's hydraulic punch equipment, such as the SEP-120, includes a 12-month warranty covering parts against defects in materials or workmanship. Contact Piranha directly for full warranty terms and details specific to ironworker models.

Most ironworker models are in stock and ready to ship immediately, with the exception of the PII series which may require lead time. The SEP-120 single-end punch ships from stock subject to order confirmation, ExWorks from the Rockford, Illinois factory.
