Hertel K008156AS25 Spiral Point Tap 6-32 Unc Tin Hss

Product Description

The HERTEL K008156AS25 is a spiral point tap designed for cutting 6-32 UNC internal threads in through-hole applications. Built from high-speed steel (HSS) with a titanium nitride (TiN) coating, it delivers extended tool life and reduced friction during tapping operations. The plug chamfer style provides a gradual lead-in suited to most standard through-hole tapping work. At 2.0 inches overall length with a right-hand thread direction and H2 thread limit, this tap is sized for use in hand tapping setups and conventional machine tapping on drill presses, CNC machining centers, and tapping machines. It carries a 3B class of fit, producing threads within standard tolerance for general-purpose fastener engagement.

This tap is intended for threading 6-32 UNC holes in light metals, mild steels, plastics, and similar machinable materials where a through-hole is present. The spiral point design pushes chips forward ahead of the cutting action, making it well suited to production tapping in through-hole bores rather than blind holes. Machinists, tool-and-die technicians, and maintenance professionals working in fabrication, assembly, or MRO environments will find this tap appropriate for standard 6-32 fastener thread preparation.

Key Features

• 6-32 UNC thread form for standard coarse-pitch inch-series threading
• Spiral point geometry pushes chips forward, reducing chip packing in through-hole applications
• TiN coating improves wear resistance and lubricity for longer tool life
• High-speed steel construction withstands the heat generated in machine tapping
• H2 thread limit holds tight tolerance for consistent 3B class-of-fit thread production
• Right-hand cut, plug chamfer — compatible with standard tapping chucks and holders

Compatibility

Designed as an OEM-style replacement or direct-use spiral point tap for any machine or hand tapping setup requiring a 6-32 UNC right-hand tap with a standard shank.

Installation Notes

Installation should be performed by a machinist or qualified maintenance technician following standard tapping procedures. Ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct tap drill diameter for 6-32 UNC before beginning the tapping operation. Apply appropriate cutting fluid or tapping compound to reduce heat and improve thread finish. Never reverse a tap under power without confirming the machine or tap holder is rated for reversing cycles.
