Guhring 9044023054860 Spiral Point Tap 12-24 Unc Cobalt

Product Description

The GUHRING 9044023054860 is a spiral point tap designed for through-hole threading in a wide range of ferrous and non-ferrous materials. Built from cobalt high-speed steel and finished with an oxide coating, this plug chamfer tap handles the additional heat and wear that come with harder alloys. It cuts a 12-24 UNC thread to a 2B/3B class of fit with an H3 thread limit, providing reliable dimensional consistency across production and maintenance applications. The 3-flute spiral point geometry pushes chips forward ahead of the tap, making it well suited to through-hole work where chip evacuation is straightforward. Overall length is 2.382 inches, with a thread length of 0.629 inches.

This tap is used in machine shop, maintenance, and field repair settings wherever 12-24 UNC threads are required in through-hole configurations. The cobalt construction and oxide finish make it appropriate for demanding materials including stainless steel, tool steel, heat treatable steel, case hardened steel, cast iron, structural steel, free cutting steel, sulfured steel, aluminum, and aluminum alloys. It fits standard tap holders and machine spindles sized for the 0.220-inch shank diameter. Typical applications include production tapping on CNC machining centers, drill presses, and manual tapping operations in maintenance and repair environments.

Key Features

• Spiral point geometry pushes chips forward, optimized for through-hole threading
• Cobalt high-speed steel construction for extended tool life in hard and abrasive materials
• Oxide coating reduces friction and provides basic lubricity during cutting
• H3 thread limit and 2B/3B class of fit for consistent, interchangeable thread production
• Plug chamfer for standard starting in pre-drilled through holes
• Right-hand cut, 3-flute design compatible with standard tapping equipment

Compatibility

Designed for through-hole tapping of 12-24 UNC threads in aluminum, aluminum alloys, case hardened steel, cast iron, free cutting steel, heat treatable steel, stainless steel, structural steel, sulfured steel, and tool steel. Fits tap holders and collets designed for a 0.220-inch shank diameter.

Installation Notes

This tap is installed and operated by machinists and maintenance technicians using standard tapping equipment, including CNC machining centers, drill presses with tapping attachments, and manual tap wrenches. Always ensure the workpiece is securely fixtured and the pilot hole is drilled to the correct tap drill size for 12-24 UNC before beginning the tapping operation. Use an appropriate cutting fluid or tapping compound for the material being threaded to extend tool life and improve thread quality. Do not attempt to use this tap as a bottoming tap in blind holes without verifying adequate thread length.
