Scientific Cutting Tools TM110-36HA Thread Mill 8-36 Unf

Product Description

The SCIENTIFIC CUTTING TOOLS TM110-36HA is a helical flute thread mill designed for cutting internal 8-36 UNF threads in a single helical interpolation pass. The tool is ground from submicron-grade solid carbide and finished with a TiAlN coating for extended tool life in ferrous and hard materials. With a 0.1100 inch cutting diameter and a 0.3125 inch length of cut, it handles standard 8-36 UNF thread depths with precision. The three right-hand flutes provide efficient chip evacuation in blind and through holes. This tool is installed and operated by machinists in CNC machining centers using circular interpolation cycles.

This thread mill is suited for production and job-shop environments requiring accurate internal 8-36 UNF threads. It is commonly used on CNC vertical and horizontal machining centers in aerospace, automotive, medical device, and general manufacturing applications. The helical flute geometry and TiAlN coating make it a practical choice for threading stainless steel, alloy steel, titanium, and other demanding materials where tap breakage risk is a concern. The 1/4 inch shank diameter fits standard collet chucks and end mill holders used in most CNC setups.

Key Features

• Submicron-grade solid carbide blank for rigidity and wear resistance in hard materials
• TiAlN coating improves heat resistance and extends tool life in ferrous and exotic alloys
• Three helical flutes with right-hand cutting direction for efficient chip evacuation
• 0.1100 inch cutting diameter targets 8-36 UNF internal thread form in a single pass
• No coolant-through design - suitable for flood or mist coolant delivery externally
• Single-tool solution reduces risk of tap breakage in difficult-to-machine materials

Compatibility

Designed for cutting internal 8-36 UNF threads via CNC circular interpolation on machining centers equipped with a 1/4 inch collet chuck or end mill holder.

Installation Notes

Installation and operation should be performed by a qualified machinist familiar with CNC thread milling cycles and circular interpolation programming. Secure the 1/4 inch shank in a properly sized, clean collet or end mill holder and verify runout before cutting. Use the correct G-code helical interpolation cycle for the target thread pitch and diameter as specified by the machine controller. External flood or mist coolant is recommended since this tool does not have coolant-through capability.
