Sandvik Coromant 5758023 Threading Insert Metric 60

Product Description

The SANDVIK COROMANT 5758023 is a solid carbide laydown threading insert designed for internal Metric 60-degree thread cutting. Part of the CoroThread 266 series, this right-hand insert carries a TiN coating applied via PVD process, which supports wear resistance during threading operations. It features a 1/2-inch (12.70 mm) inscribed circle and a 5.56 mm thickness, with two teeth per side and a 60-degree included angle. Grade 1020 carbide is matched to the CoroThread 266 insert style. CNC lathe operators and machining professionals working in production or job shop environments install this insert for precision internal threading on metric-standard workpieces.

This insert is suited for internal threading operations requiring Metric 60-degree thread form at a 2.50 mm pitch. It fits CoroThread 266 compatible toolholders designed for the 22-size insert classification. Typical applications include threading bores in steel and other materials where a PVD TiN-coated solid carbide insert is appropriate for the cutting conditions. The chipbreaker style is designated A, which is relevant when selecting the insert for specific threading approaches and material types.

Installation Notes

This insert is installed and serviced by machinists or CNC lathe operators. Power down and lock out the machine spindle before changing inserts. Use the correct torque wrench and clamping screw specified for the CoroThread 266 holder to avoid cracking the carbide substrate. Confirm insert orientation and hand designation match the toolholder before engaging the cut.
