Hertel K008159AS Spiral Point Tap 6-32 Unc Bottoming Hss

Product Description

The HERTEL K008159AS is a spiral point tap designed for cutting internal threads in through-hole applications. Built from high-speed steel with a bright uncoated finish, it cuts 6-32 UNC threads to a 3B class of fit with an H2 thread limit. The spiral point geometry pushes chips forward ahead of the tap rather than packing them in the flutes, keeping the cutting zone clear during the threading operation. With 2 flutes and a bottoming chamfer, this tap is suited for threading close to the bottom of a blind hole or achieving maximum thread engagement in shallow workpieces. Overall length is 2 inches with a thread length of 0.6875 inches. Machinists, tool-and-die makers, and maintenance technicians are the primary users.

This tap is used in metalworking applications requiring precise 6-32 UNC internal threads in ferrous and non-ferrous materials. The bottoming chamfer makes it appropriate for workpieces where thread depth is critical and a longer lead chamfer would not reach full thread form before the bottom of the hole. It is commonly used in production machining, machine shops, and maintenance-repair-operations environments where 6-32 machine screw threads are standard.

Key Features

• 6-32 UNC thread form with right-hand thread direction
• Bottoming chamfer for threading close to the base of a hole
• H2 thread limit for controlled 3B class of fit tolerances
• High-speed steel construction for durability across common workpiece materials
• Bright uncoated finish suitable for use with standard cutting fluids
• Spiral point design pushes chips forward to reduce clogging in through-hole applications

Compatibility

Designed as a standard 6-32 UNC spiral point tap compatible with tap holders and tapping heads configured for that thread size and shank geometry.

Installation Notes

This tap is installed and driven by a licensed machinist or qualified maintenance technician using a tap wrench, tapping head, or CNC tapping spindle. The workpiece must be securely fixtured before tapping begins. Use an appropriate cutting fluid for the workpiece material to reduce heat and extend tool life. Inspect the tap for chipping or wear before each use; a damaged tap can seize in the hole and damage the workpiece.
