Scientific Cutting Tools TT150750A Threading Tool Internal

Product Description

The SCIENTIFIC CUTTING TOOLS TT150750A is a solid carbide single point threading tool designed for internal thread cutting on CNC lathes and threading equipment. With a minimum threading diameter of 0.15 inches and a cutting depth of 0.75 inches, it handles a wide TPI range from 20 to 56. The 60-degree profile angle suits unified and metric thread forms commonly produced in precision machining environments. The AlTiN+ coating provides thermal resistance and extended tool life in ferrous and hardened materials. This tool is used by machinists and tool-and-die professionals who require consistent thread geometry at small bore diameters.

This threading tool is suited for internal threading operations in small-diameter bores on production machining centers and manual lathes. The 3/16-inch shank diameter and 2-inch overall length make it compatible with standard toolholders used in bench and CNC turning applications. It is appropriate for threading stainless steel, alloy steel, and other materials where the AlTiN+ coating delivers heat and wear resistance. Typical applications include threading hydraulic fittings, precision fluid components, and small mechanical assemblies requiring clean, accurate internal threads.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding threading operations
• AlTiN+ coating for extended tool life and high-temperature performance
• 60-degree profile angle compatible with unified and metric thread forms
• Wide TPI range of 20 to 56 reduces tooling changeovers in mixed-production environments
• 0.035-inch projection from edge for clearance in tight bore geometries
• No coolant-through design simplifies setup on standard toolholding systems

Compatibility

Designed as an OEM-style single point threading tool for use in standard 3/16-inch bore toolholders on CNC and manual lathes performing internal threading operations.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's setup procedures. Secure the shank firmly in the toolholder to the specified clamping torque listed in the toolholder documentation before operation. Verify tool overhang and bore clearance against the 0.035-inch edge projection before beginning a threading cycle. Power down and lock out the machine before changing or indexing any cutting tool.
