Hertel K008929AS Tap Set 1/2-13 Unc 4 Flute Hss 3 Pc

Product Description

The HERTEL K008929AS is a 3-piece tap set designed for cutting 1/2-13 UNC internal threads in metal workpieces. Manufactured from high speed steel with a bright finish, the set includes taps suited for progressive thread-cutting stages in a single unified thread form. The 1/2-13 UNC designation indicates a half-inch nominal diameter with 13 threads per inch, a common fastener standard in general machining and mechanical assembly. With an overall length of 3.375 inches and a 4-flute geometry, these taps are built for controlled chip evacuation and consistent thread formation in ferrous and non-ferrous materials.

This tap set is used in production and maintenance machining environments where 1/2-13 UNC threaded holes are required. Typical applications include fabrication shops, industrial maintenance, and mechanical repair operations. The 2B and 3B class of fit coverage makes the set suitable for standard-tolerance and close-tolerance thread requirements across a range of general-purpose and precision assembly work. The 4-flute design and H3 thread limit support accurate thread profile generation in through-holes and blind-hole applications.

Compatibility

Designed as a general-purpose replacement or service tap set for applications requiring 1/2-13 UNC internal threads with 2B or 3B class of fit tolerances.

Installation Notes

Tap installation and use should be performed by qualified machinists or trade professionals familiar with thread-cutting operations. Always secure the workpiece properly and use appropriate tapping fluid or cutting oil to extend tool life and improve thread quality. Power down and de-energize any machine tool before changing or setting taps. Follow applicable shop safety standards and machine tool manufacturer guidelines during setup and operation.
