Scientific Cutting Tools TT230600A Threading Tool Internal

Product Description

The SCIENTIFIC CUTTING TOOLS TT230600A is a solid carbide single point threading tool designed for internal threading operations on CNC lathes and turning centers. It covers a range of 14 to 40 threads per inch (TPI) with a minimum threading diameter of 0.23 inches, making it suitable for smaller-bore internal thread forms. The tool features a 60-degree profile angle, a cutting depth of 0.6 inches, and an AlTiN Plus physical vapor deposition coating that extends tool life in ferrous and hardened materials. The 5/16-inch shank and 2.5-inch overall length provide rigid tool holding in standard boring bar-style setups.

This tool is intended for internal threading on precision machined parts in production and job-shop environments. It suits applications where consistent thread geometry on smaller-diameter bores is required, including hydraulic fittings, pneumatic components, and threaded fastener bosses. The 60-degree profile is the standard included angle for Unified National (UN) and metric thread forms, so this tool fits comfortably into general-purpose threading programs. Machinists working with CNC lathes, Swiss-type machines, or manual lathes with threading capability are the primary end users.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding threading operations
• AlTiN Plus coating improves heat resistance and extends tool life when threading ferrous alloys
• 60-degree profile angle compatible with standard UN and metric thread forms
• Covers 14 to 40 TPI range from a single tool, reducing tooling changeovers
• 0.23-inch minimum threading diameter suitable for small-bore internal thread applications
• 0.055-inch projection from edge and 0.6-inch cut depth for controlled engagement

Compatibility

Designed as a direct-fit internal single point threading tool for 5/16-inch shank tool holders used on CNC lathes, manual lathes, and turning centers capable of single point threading cycles.

Installation Notes

Installation should be performed by a qualified machinist familiar with single point threading toolpaths and G-code threading cycles. Secure the shank firmly in a compatible tool holder and verify that shank runout is within acceptable limits before threading. Power down and lock out the machine before changing or repositioning the tool. Do not use coolant-through features with this tool, as coolant-through is not supported.
