Scientific Cutting Tools TMI120-32HA Thread Mill 10-32

Product Description

The SCIENTIFIC CUTTING TOOLS TMI120-32HA is a helical flute thread mill designed for cutting internal 10-32 UNF threads in a single helical pass. Built from submicron solid carbide and finished with an AlTiN+ coating, this tool delivers high wear resistance and thermal stability in demanding milling applications. It features 3 right-hand flutes, a cutting diameter of 0.1200 inches, a length of cut of 0.3260 inches, and an overall length of 2.5000 inches. The long-reach design gives machinists access to threads in recessed or deep-pocket features without interference. This tool is installed and run by CNC machinists and tool-and-die professionals working in precision threading operations.

This thread mill is suited for internal 10-32 UNF threading in ferrous and non-ferrous materials where a solid carbide helical flute tool is required. The long-reach configuration makes it appropriate for production and job-shop environments handling parts with limited spindle clearance or deep threaded features. It is run on CNC machining centers using helical interpolation. The 1/4 inch shank diameter accommodates standard end mill holders and collet chucks commonly found in these setups.

Key Features

• Internal 10-32 UNF thread profile with 32 teeth per inch
• Submicron solid carbide blank for rigidity and edge retention
• AlTiN+ coating provides high-temperature hardness and oxidation resistance
• 3 right-hand helical flutes for efficient chip evacuation
• Long-reach design allows threading in recessed or deep-pocket bores
• 0.1200 inch cutting diameter with 0.3260 inch length of cut

Compatibility

Designed as an OEM-style thread milling solution for CNC machining centers capable of helical interpolation and accepting a 1/4 inch shank end mill toolholder or collet chuck.

Installation Notes

Thread mills of this type are installed by qualified CNC machinists and require a machining center with helical interpolation capability. Confirm proper tool stick-out and runout before cutting to avoid thread form error. Always verify spindle speed, feed rate, and helix parameters against the tool manufacturer's cutting data for the workpiece material. Inspect the cutting edges and coating condition before each use; carbide thread mills should not be run if chipping or coating failure is visible.
