Scientific Cutting Tools TT2301250A Threading Tool Internal

Product Description

The SCIENTIFIC CUTTING TOOLS TT2301250A is a single point internal threading tool engineered for precision thread cutting in bore and hole applications. Built from solid carbide and coated with an AlTiN+ finish, it delivers hardness and heat resistance well suited to demanding cutting conditions. The tool handles a thread range of 14 to 40 TPI with a 60-degree profile angle, covering a wide span of common unified and metric-style thread forms. A 1.25-inch cutting depth and 5/16-inch shank diameter provide reach and rigidity for internal threading operations on CNC lathes and turning centers. Minimum threading diameter starts at 0.23 inches.

This tool is designed for internal threading operations in production and job-shop machining environments. It is suited for use in CNC turning centers and lathes where consistent thread form and finish are required in bores and through-holes. The solid carbide construction makes it appropriate for threading in steel, stainless steel, aluminum, and similar materials where tool life and dimensional accuracy are priorities. The AlTiN+ coating adds lubricity and oxidation resistance, extending tool life in dry or semi-dry cutting conditions. Licensed machinists and CNC operators are the primary users.

Key Features

• Solid carbide construction for rigidity and long tool life in internal threading
• AlTiN+ coating provides heat and oxidation resistance in demanding cutting conditions
• 60-degree profile angle covers unified thread forms across a 14 to 40 TPI range
• 1.25-inch cutting depth allows threading deep into bores from a 5/16-inch shank
• 0.055-inch projection from edge for precise thread engagement geometry
• No coolant-through design simplifies setup on standard tooling setups

Compatibility

Designed as an OEM-style single point internal threading tool suitable for use in standard 5/16-inch shank toolholders on CNC lathes and turning centers.

Installation Notes

Installation and use of this tool is performed by qualified machinists or CNC operators. Ensure the machine spindle is fully stopped and the toolholder is properly torqued before beginning any setup. Confirm shank-to-holder fit and runout before initiating a threading pass. Do not exceed the rated TPI range or minimum threading diameter for this tool.
