Pro-source 5590020011PRO Shear Nibbler Die

Product Description

The PRO-SOURCE 5590020011PRO is a replacement die designed for use with handheld air nibblers. The die is the cutting insert that enables the nibbler to shear through sheet metal in a controlled, straight-line or curved path. When a die wears or chips from repeated use, replacing it restores the tool to full cutting performance. This part ships as a single die and is a direct-fit replacement for air nibbler tooling that accepts this die profile. At 0.5 inches in each dimension and 0.5 pounds, it is a compact, lightweight component suited for sheet metal fabrication, HVAC ductwork, and general metalworking applications.

Handheld air nibblers are standard tools in HVAC fabrication shops and field service where technicians need to cut galvanized sheet metal, duct board, or light-gauge steel without distorting the material edge. The die works in tandem with the nibbler punch to progressively remove small chips of material. This replacement die is appropriate for any technician or fabricator performing routine tooling maintenance on a compatible air nibbler unit.

Installation Notes

Installation should be performed by a qualified technician familiar with pneumatic hand tool maintenance. Disconnect the air supply to the nibbler before removing or installing any tooling components. Follow the tool manufacturer's instructions for die removal and seating to avoid damage to the punch assembly. Inspect the punch for wear at the same time as die replacement, as paired wear is common.
