Hertel K011224AS Spiral Point Tap 10-24 Unc Hss

Product Description

The HERTEL K011224AS is a spiral point tap designed for cutting 10-24 UNC internal threads in through-hole applications. Built from high speed steel with a bright finish, this plug chamfer tap drives chips forward ahead of the cutting zone, making it well suited for production threading in metals and other machinable materials. The H5 thread limit provides a controlled tolerance fit for standard UNC fastener assemblies. With a 0.194-inch shank diameter and a 0.875-inch thread length, the tap fits standard tapping chucks and holders used in manual and CNC machining operations.

This tap is intended for right-hand threading in through-holes where chip evacuation is a priority. The two-flute spiral point geometry pushes chips forward rather than backing them out, reducing the risk of chip packing in moderate-depth holes. It is a standard trade-supply item for machinists, maintenance mechanics, and tool crib stock in manufacturing and repair environments. The plug chamfer allows the tap to start easily and thread progressively through the full depth of the through-hole.

Key Features

• Spiral point geometry pushes chips forward, ideal for through-hole tapping
• High speed steel construction handles a broad range of machinable metals
• Plug chamfer for progressive thread engagement and easy starting
• H5 thread limit for controlled UNC tolerance fit
• Bright finish with no coolant-through requirement, simplifying setup
• Right-hand thread direction, compatible with standard tapping equipment

Compatibility

Designed as a standard replacement or stock tap for 10-24 UNC through-hole threading operations using conventional tapping chucks, drill press setups, or CNC tapping cycles that accept a 0.194-inch shank diameter.

Installation Notes

Installation and use should be performed by a qualified machinist or maintenance mechanic familiar with tapping feeds, speeds, and cutting fluid selection for the workpiece material. Ensure the workpiece is securely fixtured and the tap is aligned perpendicular to the hole before engagement. Use an appropriate cutting fluid or tapping compound to extend tool life and improve thread finish. Do not force a tap that has stopped turning freely, as this risks breakage and workpiece damage.
