Hertel K008155AS25 Spiral Point Tap 6-32 Unc Tin Hss

Product Description

The HERTEL K008155AS25 is a spiral point plug tap designed for cutting 6-32 UNC threads in through-hole applications. Built from high-speed steel (HSS) with a titanium nitride (TiN) coating, this tap delivers extended tool life and reduced friction during cutting. The plug chamfer — typically 3 to 5 threads — makes it suitable for through-hole tapping where the tap can push chips ahead of the cutting edge rather than backing them out. With 2 flutes and a right-hand thread direction, this tap is a standard workhorse for machine shops, maintenance technicians, and field service professionals working with small-diameter fastener threads.

This tap is intended for tapping 6-32 UNC threads in a range of materials commonly encountered in light manufacturing, mechanical assembly, and equipment repair. The TiN coating improves performance in ferrous and non-ferrous metals alike, including steel, aluminum, and brass. With an overall length of 2 inches and a thread length of 11/16 inches, it fits standard tap holders and chucks used in both CNC and manual tapping operations. The H1 thread limit keeps finished threads within close tolerance for reliable fastener fit.

Key Features

• 6-32 UNC thread form with right-hand cut for standard fastener compatibility
• Plug chamfer pushes chips forward, optimized for through-hole tapping
• High-speed steel construction withstands heat generated during machine tapping
• TiN coating reduces friction and extends tool life compared to uncoated HSS
• H1 thread limit ensures tight tolerance control on finished threads
• 2-flute design balances chip clearance and cutting edge strength at this thread size

Compatibility

Designed as an OEM-style replacement or direct-use tap for standard 6-32 UNC through-hole tapping applications. Fits tap holders and chucks accepting a 0.141-inch shank diameter.

Installation Notes

This tap is installed and operated by machinists, tool and die technicians, and mechanical service professionals using a tap wrench, tapping head, or CNC rigid-tap holder. Always secure the workpiece and ensure proper alignment before tapping to prevent tap breakage at this small diameter. Use an appropriate cutting fluid or tapping compound to reduce heat and extend tool life. Follow shop safety practices and machine guarding requirements when power tapping.
