Allied TM19032-3T3X Thread Mill 10-32 3 Flute Solid Carbide

Product Description

The ALLIED MACHINE AND ENGINEERING TM19032-3T3X is a solid carbide helical flute thread mill designed for cutting 10-32 UN threads in both internal and external applications. It features a 0.1450-inch cutting diameter, a 0.5900-inch length of cut, and a 2.5000-inch overall length. The 3-flute, left-hand flute direction geometry paired with AM210 coating supports efficient chip evacuation and extended tool life in precision threading operations. This tool is intended for use on CNC machining centers operated by skilled machinists working to tight thread tolerances.

This thread mill is suited for job shops, production machining environments, and toolrooms where 10-32 UN threads are required in a range of materials. The long-reach thread mill type makes it appropriate for applications where access depth or clearance constraints prevent the use of standard-length tooling. Both through-hole and blind-hole threading applications are supported given its internal and external capability. No coolant-through feature is present, so external coolant or cutting fluid delivery should be planned accordingly.

Key Features

• Cuts 10-32 UN threads — internal and external — in a single helical interpolation pass
• Solid carbide construction for rigidity and dimensional stability under cutting loads
• AM210 coating for improved wear resistance and reduced friction at the cutting edge
• Left-hand helical flute direction with 3 flutes for balanced cutting forces and chip flow
• Long-reach thread mill type accommodates restricted-access and deep-feature applications
• 0.2500-inch shank diameter compatible with standard ER and precision collet systems

Compatibility

Designed for use in CNC machining centers capable of helical interpolation. Compatible with standard 1/4-inch collet chucks and shrink-fit holders. Cuts 10-32 UN threads per the UN thread standard.

Installation Notes

Thread milling requires a CNC machining center with 3-axis helical interpolation capability — confirm controller support before programming. Secure the shank in a balanced, low-runout collet or shrink-fit holder; excessive runout will degrade thread quality and reduce tool life. Verify spindle speed, feed rate, and helical pitch values against the manufacturer programming guidelines for the specific workpiece material before cutting. Disengage machine power and follow lockout/tagout procedures before changing or inspecting the tool.
