Guhring 9044093048260 Spiral Flute Tap 10-32 Unf

Product Description

The GUHRING 9044093048260 is a spiral flute tap designed for right-hand threading in blind hole applications. Built from cobalt high-speed steel with an oxide finish, it cuts 10-32 UNF threads with a modified bottoming chamfer that allows threading close to the bottom of a hole. The 40-degree helix angle promotes chip evacuation up and out of the hole, making it well suited for the shorter chip materials this tool targets. Overall length is 2.382 inches with a thread length of 0.334 inches and a tapping depth of 0.945 inches. Suitable for use by machinists and tool-and-die professionals in production or job-shop environments.

This tap is intended for blind hole threading in aluminum, brass, and gray cast iron. The modified bottoming chamfer produces threads closer to the bottom of a blind hole than a standard plug tap, making it a practical choice when thread engagement depth is limited. The H3 thread limit keeps tolerances tight enough for 2B and 3B class-of-fit requirements on 10-32 UNF fastener applications in both light assembly and precision machining work.

Key Features

• Modified bottoming chamfer for threading near the base of blind holes
• Cobalt construction for improved heat and wear resistance compared to standard HSS
• 40-degree right-hand spiral flute promotes chip evacuation in blind hole conditions
• Oxide finish reduces friction and provides light corrosion resistance
• H3 thread limit supports 2B and 3B class-of-fit tolerances
• Fast flute style rated for aluminum, brass, and gray cast iron

Compatibility

Designed for blind hole threading in aluminum, brass, and gray cast iron workpieces requiring 10-32 UNF right-hand threads at 2B or 3B class of fit. Part of GUHRING Series 4409.

Installation Notes

This tap is installed and operated by machinists using a tapping head, CNC machine, or hand tap wrench — ensure the spindle and workpiece are properly secured before tapping. Power down or disengage the machine before changing tooling. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain thread quality. Do not exceed the recommended tapping depth of 0.945 inches to avoid tool breakage in blind holes.
