Scientific Cutting Tools TM735-14N Thread Mill 1-14 Uns 6 Flutes

Product Description

The SCIENTIFIC CUTTING TOOLS TM735-14N is a straight flute thread mill designed to cut 1-14 UNS threads in both external and internal applications. Built from powdered metal and finished with a TiCN coating, this tool delivers consistent thread geometry and extended tool life in production and job-shop environments. The 0.735-inch cutting diameter and 1.314-inch length of cut handle full-depth threading in a single helical pass. With 6 flutes and a 3/4-inch shank diameter, this thread mill is suited for CNC machining centers where rigid toolholding and precise interpolation are standard practice.

This thread mill is used in CNC milling operations requiring 1-14 UNS external or internal threads. It is well suited for threading operations in aerospace, automotive, and industrial manufacturing where thread milling is preferred over tapping - particularly in difficult-to-machine materials, blind holes, or applications where a single tool must handle both external and internal thread profiles. A licensed machinist or CNC programmer handles setup and programming for helical interpolation.

Key Features

• Cuts 1-14 UNS threads in both external and internal configurations with one tool
• Powdered metal construction provides wear resistance in demanding materials
• TiCN coating reduces friction and extends tool life at elevated cutting temperatures
• 6-flute straight design promotes chip clearance and consistent thread form
• 3/4-inch shank diameter suits standard CNC toolholders and collet chucks
• No coolant-through design - suitable for flood or mist coolant applied externally

Compatibility

Designed for CNC machining centers capable of helical interpolation. Threads produced conform to the UNS standard at 1-14 TPI for both external and internal thread forms. Minimum nominal thread diameter is 1 inch.

Installation Notes

This tool is installed and operated by a qualified CNC machinist or tooling engineer. Secure the 3/4-inch shank in a precision collet chuck or milling toolholder before use. Thread milling requires a helical interpolation routine programmed to the correct pitch and cutting diameter - verify G-code parameters before cutting. Never run this tool in a conventional tapping cycle; thread mill routines only.
