Irwin 12428 Round Die Stock 1 in Die 9 in Length

Product Description

The IRWIN 12428 is a round die stock designed to hold and drive round threading dies during hand-threading operations. Constructed from high-speed steel, this die stock provides the rigidity and durability required for cutting external threads on pipe, rod, and fastener stock. The 12428 accepts round dies with a 1 inch outside diameter and measures 9 inches in overall length, giving the technician sufficient leverage for controlled thread cutting. Plumbers, pipefitters, machinists, and HVAC technicians rely on this type of tool when threading pipe or all-thread rod in the field or at the bench.

The IRWIN 12428 is suited for use in residential and commercial trade applications where hand threading is required. Typical scenarios include threading galvanized or black iron pipe nipples, cutting threads on repair studs, and field-fabricating threaded connections when a powered threading machine is not available. The 9 inch handle length provides adequate torque for threading through common mild steel and iron stock without excessive operator fatigue.

Key Features

• High-speed steel construction for durability and resistance to wear during threading operations
• Accepts round dies with a 1 inch outside diameter
• 9 inch overall length provides controlled leverage for hand threading
• Round die shape compatibility suits standard threading die sets used across trade applications
• Compact and lightweight at 0.5 pounds for portable field use

Compatibility

Designed to accept standard round threading dies with a 1 inch outside diameter, consistent with common round die sets used in plumbing, pipefitting, and general mechanical trades.

Installation Notes

Round die stocks are used by licensed plumbers, pipefitters, and mechanical technicians performing hand-threading work. Secure the workpiece firmly in a vise before threading to prevent movement and ensure clean thread cuts. Apply cutting oil to the die and workpiece before and during threading to reduce heat and extend die life. Inspect the die seating in the stock and ensure the set screw is tightened securely before applying torque.
