HSS Hand Tap Set NF 1 3/8" 12 TPI

This HSS hand tap set is specifically designed for cutting NF 1 3/8" internal threads with 12 threads per inch. Manufactured from high-quality high-speed steel (HSS), this set guarantees long service life and high precision.

The set typically includes multiple taps (taper, intermediate, and bottoming taps) to cut the thread in several passes. This enables clean and precise results, even with difficult materials. The precisely manufactured cutting geometries ensure easy entry and optimal chip evacuation.

Ideal for use in workshops, mechanical engineering, and maintenance. With this tap set, you can reliably and professionally create internal threads to specification.

When threading, please observe the appropriate spindle speeds and cutting oils to extend the service life of the taps and achieve optimal results.
