Milwaukee Tool 48-36-1111 Pipe Threader Dies 1.5in Npt

Product Description

The MILWAUKEE TOOL 48-36-1111 is a set of pipe threader dies designed to cut 1-1/2 inch NPT threads in both left-hand and right-hand directions. Constructed from high-speed steel, these dies deliver the hardness and wear resistance needed for repeated threading cycles on steel, iron, and similar pipe materials. Licensed plumbers, pipefitters, and mechanical contractors use this set when working with standard NPT-threaded pipe assemblies in commercial and industrial piping systems. The high-speed steel construction maintains cutting edge integrity under the heat generated during threading, reducing the need for frequent die replacement in high-volume work.

These dies are suited for threading 1-1/2 inch nominal pipe in applications where both left-hand and right-hand thread orientations are required. Typical use cases include plumbing rough-in, gas piping, fire suppression systems, and mechanical process piping where NPT thread standards apply. The dual-direction capability makes this set useful for installations involving union connections or counter-rotating assemblies. The 0.46-pound weight keeps the die set manageable during transport between job sites.

Key Features

• Cuts 1-1/2 inch NPT threads to standard thread form
• Supports both left-hand and right-hand thread directions in one set
• High-speed steel construction resists heat and wear during repeated threading operations
• Lightweight at 0.46 pounds for easy handling on the job site
• Meets UNSPSC classification 27112805 for pipe threading tooling

Compatibility

Designed as an OEM-style replacement die set for pipe threader machines that accept 1-1/2 inch NPT dies; consult your threader manufacturer documentation to confirm die seat compatibility before installation.

Installation Notes

Die installation and replacement should be performed by a licensed plumber or pipefitter familiar with pipe threading equipment. Disengage and lock out the threader machine before removing or seating dies. Ensure the die head is clean and free of debris before installing the new set. Apply appropriate threading oil during all threading operations to extend die life and produce clean thread form.
