Sandvik Coromant 5726668 Single Point Threading Tool

Product Description

The SANDVIK COROMANT 5726668 is a solid carbide single point threading insert designed for internal thread cutting in precision machining applications. It produces 60-degree profile threads at up to 20 threads per inch (TPI), with a minimum threading diameter of 0.2441 inches and a cutting depth of 0.0268 inches. The tool measures 1.4685 inches overall length with a 0.5906-inch projection from edge. A TiAlN and titanium nitride dual coating provides thermal resistance and extended tool life in demanding cutting conditions. This tool is typically installed by machinists and CNC tooling technicians working on lathe or turning center setups.

This threading tool is suited for internal threading operations on ferrous and non-ferrous workpieces in job shop and production machining environments. It is designed for use in CNC lathes and turning centers where small-diameter internal threads are required. The 60-degree profile angle makes it compatible with Unified National (UN) and metric thread forms within its specified TPI and pitch range. The solid carbide construction supports higher cutting speeds and tighter tolerances compared to high-speed steel alternatives.

Key Features

• Solid carbide construction for rigidity and wear resistance in internal threading operations
• 60-degree profile angle compatible with UN and metric thread forms
• TiAlN and titanium nitride coating for heat resistance and extended tool life
• 0.2441-inch minimum threading diameter supports small-bore internal thread work
• 20 TPI maximum thread capacity with 1.25 mm minimum pitch
• 0.5906-inch projection from edge for reach into confined bore geometries

Compatibility

Designed as a direct-fit single point threading tool for CNC lathes and turning centers requiring internal 60-degree profile thread cutting with a minimum bore diameter of 0.2441 inches.

Installation Notes

Installation and tool setup should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the tool holder is properly torqued before engaging the insert. Verify tool projection and center height alignment prior to cutting to avoid thread form errors. Coolant-through is not supported on this tool; external coolant application should be directed to the cutting zone per standard shop practice.
