Hertel K008152AS Straight Flute Tap 6-32 Unc Hss

Product Description

The HERTEL K008152AS is a straight flute bottoming tap designed for cutting internal threads in pre-drilled holes where threads must extend close to the bottom of a blind bore. Manufactured from high-speed steel with a bright/uncoated finish, this tap cuts a 6-32 UNC right-hand thread to a 2B class of fit with an H3 thread limit. The three-flute straight flute design provides adequate chip clearance in through-hole applications and controlled cutting action in short blind holes. Overall length is 2 inches. It is used by machinists, maintenance technicians, and tool-and-die professionals working with fine-thread fastener sizing in ferrous and non-ferrous materials.

This tap is suited for production and maintenance threading operations where a 6-32 UNC thread form is required. The bottoming chamfer leaves only 1 to 2 threads of lead-in, making it the correct choice when threads are needed as deep as possible in a blind hole. It is commonly used after a taper or plug tap has started the thread. Applications include light sheet metal fabrication, electronic enclosure assembly, and general machine repair where No. 6 fasteners are specified.

Installation Notes

This tap is installed using a standard tap wrench, T-handle, or tapping head sized for the shank diameter. Always ensure the workpiece is securely fixtured before tapping. Use an appropriate cutting fluid for the material being threaded to extend tap life and improve thread quality. Follow the pre-drilled hole diameter specification for a 6-32 UNC thread as defined in standard tap drill charts before beginning the threading operation.
