Allied Machine TM19032 Thread Mill 10-32 Un 3 Flute Tialn

Product Description

The ALLIED MACHINE AND ENGINEERING TM19032 is a helical flute thread mill designed for cutting 10-32 UN threads in both internal and external applications. It features a 0.120-inch cutting diameter, a 0.125-inch shank diameter, and a length of cut of 0.312 inches with a 2-inch overall length. The three-flute geometry and TiAlN coating support efficient chip evacuation and thermal resistance during high-speed threading operations. This tool is installed and operated by machinists, toolroom technicians, and CNC operators working in precision threading applications where thread form accuracy is required in a compact diameter range.

This thread mill is suited for use in CNC machining centers capable of helical interpolation. It is appropriate for both through and blind-hole internal threading as well as external thread milling on small-diameter features. The 10-32 UN thread form makes it a common selection for instrument hardware, fastener tapping in aluminum and steel components, and other precision assemblies requiring fine-thread profiles in tight spaces. No coolant-through capability is present, so flood or mist cooling from the spindle environment should be managed at the machine setup level.

Key Features

• Cuts 10-32 UN threads in both internal and external configurations with a single tool
• TiAlN coating provides oxidation resistance and hardness at elevated cutting temperatures
• Three-flute helical design promotes chip evacuation and smooth thread form generation
• 0.120-inch cutting diameter suits small-feature threading where tap clearance is limited
• 0.312-inch length of cut accommodates typical thread engagement depths for 10-32 fastener applications
• 2-inch overall length provides standard gage-line reach for most CNC tool holders

Compatibility

Designed for use in CNC machining centers with helical interpolation capability; compatible with standard 1/8-inch diameter collet chucks and tool holders for small-diameter end mills and thread mills.

Installation Notes

Thread mills require a CNC control capable of helical interpolation to generate the thread form correctly. Secure the 0.125-inch shank in a precision collet or tool holder rated for the shank diameter, and verify runout before cutting. Confirm spindle speed, feed rate, and interpolation radius are programmed to match the 10-32 UN thread form specifications. Do not use in manual or non-interpolating machines, as incorrect motion will destroy the tool and damage the workpiece.
