Eagle Cutting Tool NHD-2500-18-I Carbon Npt Pipe Hex Die

Product Description

The EAGLE CUTTING TOOL NHD-2500-18-I is a 1/4-18 carbon steel NPT pipe hex die designed for cutting external National Pipe Taper threads on pipe and fittings. The hex body profile seats in standard hex die stocks and hand-operated threading tools, making it a practical choice for plumbers, pipefitters, and mechanical contractors who need to cut tapered pipe threads in the field or shop. At 0.37 pounds, it is a lightweight tool that handles 1/4-inch nominal pipe size with an 18-thread-per-inch taper pitch per NPT specification.

This hex die is suited for threading carbon steel pipe and fittings in residential and commercial plumbing, gas piping, and mechanical systems where NPT taper threads are the standard connection type. Typical applications include fabricating threaded pipe assemblies, rethreading damaged pipe ends, and cutting fresh threads on cut-to-length pipe stock. The 1/4-18 size corresponds to 1/4-inch nominal pipe, which is common in gas supply lines, compressed air distribution, and hydraulic piping installations.

Key Features

• 1/4-18 NPT taper thread profile for standard pipe thread compatibility
• Hex body design seats in common hex die stocks and threading handles
• Carbon steel construction provides cutting hardness suitable for threading mild steel pipe
• Lightweight at 0.37 pounds for easy field handling
• Import grade offers a cost-effective option for general-purpose threading work

Compatibility

Designed for use with standard hex die stocks that accept 1/4-18 NPT hex dies. Suitable for threading 1/4-inch nominal carbon steel or mild steel pipe to NPT taper thread specifications.

Installation Notes

This die is installed and operated by a licensed plumber, pipefitter, or qualified mechanical tradesperson using a compatible hex die stock or threading handle. Secure the workpiece firmly in a pipe vise before threading to prevent movement and ensure thread quality. Apply cutting oil generously during the threading operation to extend die life and produce clean thread form. Follow applicable code requirements under the IFGC or IPC when cutting threads for gas or plumbing piping systems.
