Allied Machine HDTM19032 Thread Mill 10 Un 3 Flute Tialn

Product Description

The ALLIED MACHINE AND ENGINEERING HDTM19032 is a helical flute thread mill designed for cutting unified national (UN) standard threads in both internal and external applications. It features a 0.187-inch shank diameter, a 0.150-inch cutting diameter, and 3 flutes with a TiAlN coating that extends tool life in ferrous and non-ferrous materials. The cutting length of cut is 0.312 inches and the overall length is 2.5 inches. This tool is suited for CNC machining centers where a single tool must handle both thread directions, reducing tool changes and setup time. Machinists and tool-and-die professionals are the primary users of this cutter.

This thread mill is used in precision CNC milling operations requiring #10 UN thread profiles at 32 threads per inch. It handles both internal thread milling in blind and through-holes and external thread milling on bosses and studs. Typical applications include production machining of aluminum, steel, stainless, and similar materials in job shop, aerospace, and general manufacturing environments. The helical flute geometry promotes chip evacuation during the thread milling cycle, which is especially important in deep or interrupted cuts.

Key Features

• Cuts #10-32 UN threads in both internal and external configurations with a single tool
• TiAlN coating improves heat resistance and extends tool life in ferrous and non-ferrous materials
• 3 helical flutes promote chip evacuation during thread milling cycles
• 0.150-inch cutting diameter with 0.312-inch length of cut suits tight-tolerance hole applications
• Coolant-through is not required, compatible with flood or mist coolant delivery
• 2.5-inch overall length provides clearance for standard toolholders on CNC machining centers

Compatibility

Designed as an OEM-style thread milling solution for CNC machining centers capable of helical interpolation and programmed for #10-32 UN thread profiles.

Installation Notes

This tool is installed by a machinist or tooling technician into a compatible collet or end mill holder on a CNC machining center. Ensure the machine spindle is fully stopped and the tool changer is in a safe state before handling. Thread milling requires helical interpolation capability in the CNC control; verify the correct G-code thread milling cycle and cutter compensation values are programmed before the first pass. Do not use this tool in manual milling operations.
