Sandvik Coromant 5758233 Threading Insert 6 Tpi 1/2 Ic

Product Description

The SANDVIK COROMANT 5758233 is a laydown threading insert from the CoroThread 266 series, designed for external UN thread cutting on CNC lathes and threading operations in metalworking environments. This solid carbide insert carries a PVD-applied TiN coating and features a 1/2 inch inscribed circle with a thickness of 0.2190 inches (5.56 mm). It cuts at 6 threads per inch with a 60-degree included angle, making it suited for standard unified national thread profiles. The right-hand orientation and single tooth per side design are consistent with high-precision external threading applications. Installation and use are handled by machinists and CNC tooling technicians in industrial manufacturing and job shop settings.

This insert is used in external right-hand UN thread cutting operations, typically on CNC turning centers and manual lathes requiring precise thread form accuracy. The CoroThread 266 series insert style is a common choice for production threading where consistent thread geometry and tool life are priorities. The 1020 manufacturer grade with TiN PVD coating supports general-purpose steel and moderate-alloy threading applications. It is sold in minimum order quantities of 10 units.

Compatibility

Designed for use with CoroThread 266 series toolholders that accept a 22-size insert with a 0.2244 inch (5.70 mm) hole diameter. Compatible with right-hand external UN threading applications requiring a 1/2 inch inscribed circle insert.

Installation Notes

This insert is installed and replaced by qualified machinists or CNC tooling technicians following the toolholder manufacturer seating and torque guidelines. Power down and lock out the machine spindle before changing inserts. Ensure the insert seat and clamping surfaces are clean and free of chips before seating. Follow the cutting parameter recommendations published by SANDVIK COROMANT for the 1020 grade to avoid premature edge wear.
