Scientific Cutting Tools TT230750A Threading Tool Internal

Product Description

The SCIENTIFIC CUTTING TOOLS TT230750A is a solid carbide single point threading tool designed for internal threading operations on CNC lathes and turning centers. It handles a minimum thread diameter of 0.23 inches and covers a thread pitch range of 14 to 40 TPI with a 60-degree profile angle, making it suitable for Unified and metric-profile internal threads in that range. The tool features an AlTiN+ coating for improved heat resistance and tool life in demanding materials. A 5/16-inch shank and 2.5-inch overall length keep the tool rigid in standard boring bar-style holders. Licensed machinists and CNC operators are the primary users of this tooling.

This threading tool is intended for internal thread cutting in production and job-shop environments where consistent thread form and repeatability are required. It suits residential and commercial machine shops running ferrous and non-ferrous materials where a hard, heat-resistant AlTiN+ coating extends tool life between regrinds. The 0.75-inch cutting depth allows threading into blind or through-bored features on turned components. No coolant-through capability is present, so external coolant or cutting fluid application is the appropriate method during use.

Key Features

• Solid carbide construction for rigidity and resistance to deflection during internal threading
• AlTiN+ coating improves heat resistance and extends tool life in ferrous materials
• 60-degree profile angle compatible with Unified thread forms across 14 to 40 TPI
• 0.23-inch minimum threading diameter for small-bore internal thread applications
• 0.75-inch cutting depth accommodates deep internal thread features
• 0.055-inch projection from edge for precise thread form engagement

Compatibility

Designed as an OEM-style single point threading insert tool for CNC lathes and turning centers using standard 5/16-inch bore threading tool holders for internal threading operations.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before setting or changing tooling. Secure the 5/16-inch shank firmly in the tool holder to minimize overhang and reduce chatter during threading passes. No coolant-through port is present on this tool, so direct external coolant flow to the cutting zone during operation.
