Rod Shears Shear Attachment for Ironworker

An M12 rod's shear strength depends on the material grade, but for a typical mild steel M12 rod (12mm diameter), shear strength is generally around 40-50% of its tensile strength, often estimated between 20,000-28,000 lbs of shear force. Always verify with the specific material's mechanical property datasheet before selecting shear tooling and tonnage capacity.

Piranha offers rod shear attachments across its full ironworker lineup, including single-operator P Series models (50-140 tons) and dual-operator PII and BII Series models (66-225 tons). Compatibility depends on the specific machine's tooling station and dovetail configuration, so confirm your model and serial number with Piranha customer service before ordering.

Tonnage requirements depend on rod diameter and material grade — larger diameters and higher-strength steels require more shearing force. Piranha provides a tonnage calculator tool to help fabricators match rod dimensions and material specs to the correct ironworker tonnage, ensuring clean cuts without overloading the machine.

Yes. Piranha ironworkers use a quick-change dovetail tooling design, allowing shops to switch between rod shears, flat bar shears, angle shears, and punching stations with minimal downtime. This modularity lets a single machine handle multiple cutting and punching operations in one workstation.

Routine maintenance includes inspecting blade edges for wear, keeping hold-downs and dovetail tooling slots clean, and following the lubrication schedule in the machine's service manual. Piranha provides maintenance charts, filter lists, and video tutorials to help shops keep rod shear attachments performing at spec.

Rod shear attachments are available both as standard tooling on new Piranha ironworker purchases and as add-on tooling for existing machines. Since part numbers can vary by serial number range, Piranha recommends verifying machine specifications with customer service before ordering an attachment.
