Drill Bits 6pc Steel Tap & Die Tool Threader Kit for Pipe Threading – 1/4, 3/8, 1/2 NPT

Overview

Small, robust, and ready for tough threading tasks, this six piece steel tap and die set is designed to renew and clean threads on pipe fittings and inline electrical components. Constructed from heat treated alloy steel, the taps and dies are precision ground to maintain accurate thread profiles, helping you achieve cleaner starts and smoother operation. The included wooden storage box keeps the tools organized and portable, so you can tuck the set into a tool box or a service kit for on site or workshop use. Whether you're prepping a damaged port, rethreading a hose connection, or restoring fit on a tired thread, this kit provides a practical option for standard pipe sizes.

Durable construction and precision

Heat treated and hardened alloy steel gives the taps and dies resilience under repeated use. The most substantial piece, the 1/2 inch die and tap, is designed to cut and renew internal and external 14 and 18 NPT threads on standard pipe sizes, offering a reliable option when cleaning up threads in electrical connectors and boxes. The finish is designed for smooth operation with consistent results across taps and dies, which helps you avoid cross threading and binding when you lubricate and rotate by hand or with a tap wrench.

What you get

• Sizes included: 1/4 in 18 NPT, 3/8 in 18 NPT, 1/2 in 14 NPT

Applications in the shop

In the field or workshop, threads may become dirty, damaged, or gently cross threaded. This kit offers a practical way to renew those threads, supporting a better seal on pipe connections and a tighter fit on connectors. It can be used on metal surfaces and certain hard plastics, depending on material and lubrication, and is suitable for common pipe sizes used in many projects.

Storage and care

• Keep the tools dry and clean after use
• Store in the wooden box to stay organized
• Lubricate lightly to reduce wear during use

With its steel construction, precise grinding, and portable storage, this six piece tap and die kit provides a practical option for pipe thread sizing and thread renewal tasks.
