Hertel K008135AS Spiral Point Tap 5-44 Unf Hss

Product Description

The HERTEL K008135AS is a spiral point tap designed for cutting internal threads in through-hole applications. Built from high-speed steel with a bright, uncoated finish, this 5-44 UNF tap uses a plug chamfer and two-flute spiral point geometry to push chips ahead of the cutting edge, reducing clogging and improving thread quality at production cutting speeds. The H2 thread limit holds tight tolerances for a 2B class of fit, making it a reliable choice for small-diameter threaded fastener work in metal fabrication, precision machining, and maintenance repair operations.

This tap is suited for through-hole tapping in ferrous and non-ferrous materials where chip evacuation forward through the hole is practical. The 5-44 UNF thread form covers fine-pitch applications common in instrument work, electronics assembly, small mechanical assemblies, and aerospace component repair. Right-hand thread direction is standard for conventional CW rotation on any drill press, tapping head, or CNC machine center.

Key Features

• Spiral point geometry pushes chips forward, reducing chip packing in through-hole operations
• High-speed steel construction provides good wear resistance across a broad range of workpiece materials
• Plug chamfer with 3-5 thread lead-in eases tap entry and distributes cutting load
• H2 thread limit maintains close tolerance control for 2B class of fit
• Bright, uncoated finish allows direct visual inspection of tap condition
• Right-hand, 5-44 UNF fine-pitch thread form for small-diameter precision applications

Compatibility

Designed for use in any standard tapping chuck, tapping head, drill press, or CNC machining center capable of accepting the shank diameter for a 5-44 UNF tap.

Installation Notes

A licensed machinist or qualified tool-and-die technician should select the correct tap drill size per UNF thread chart standards before tapping. Use a cutting fluid appropriate for the workpiece material to extend tap life and improve thread finish. Secure the workpiece fully before tapping to prevent deflection or tap breakage on this small-diameter tool. Inspect the tap for chipping or wear before each use, as small-diameter HSS taps are susceptible to breakage under side load or misalignment.
