Scientific Cutting Tools TMI115-32HA Thread Mill 8-32

Product Description

The SCIENTIFIC CUTTING TOOLS TMI115-32HA is a helical flute thread mill designed for cutting internal 8-32 UNC threads in a single helical pass. Built from submicron-grade solid carbide and finished with an AlTiN+ coating, this tool delivers consistent thread quality and extended tool life in demanding milling applications. With a 0.1150 inch cutting diameter and 3 right-hand flutes, it generates clean thread forms in ferrous and non-ferrous materials. The long-reach design and 2.5 inch overall length allow access to threads in recessed or deep-pocket features. Machinists and tool-and-die professionals will find this mill suited for precision CNC thread milling operations.

This thread mill is used for producing internal 8-32 UNC threads at 32 teeth per inch in CNC machining centers. The 0.2630 inch length of cut accommodates standard thread engagement depths for this thread size. The long-reach thread mill type makes it appropriate for applications where direct vertical access is limited or where thread depth requires additional clearance from the spindle nose. It is suited for use in production and job-shop environments on ferrous alloys, stainless steels, aluminum, and similar machinable materials.

Key Features

• Submicron-grade solid carbide construction for rigidity and wear resistance
• AlTiN+ coating improves heat resistance and extends tool life in high-temperature cutting
• 3 right-hand helical flutes for smooth chip evacuation during internal thread milling
• Long-reach design with 2.5 inch overall length for deep or recessed thread locations
• Cuts 8-32 UNC internal threads in a single helical interpolation pass
• No coolant-through requirement simplifies setup on standard machining centers

Compatibility

Designed for CNC machining centers capable of helical interpolation and accepting a 1/4 inch shank diameter tool holder. Suitable for milling internal 8-32 UNC threads in a range of machinable materials.

Installation Notes

This tool is installed and operated by machinists on CNC milling equipment. Verify that the machine control supports helical interpolation before programming. Secure the 1/4 inch shank in a properly sized collet or end mill holder and confirm runout before cutting. Follow the tool manufacturer's recommended feeds, speeds, and interpolation radius for the specific workpiece material.
