Sandvik Coromant 6153997 Threading Insert 6 Tpi 1/2 in Ic

Product Description

The SANDVIK COROMANT 6153997 is a solid carbide laydown threading insert designed for cutting internal Acme threads in a right-hand orientation. Part of the CoroThread 266 series, this insert carries a PVD-applied TiCrAlN/TiN coating that provides heat resistance and edge durability during threading operations. It cuts at 6 threads per inch (TPI) with a 60-degree included angle, and features a single tooth per side geometry. With a 1/2-inch inscribed circle and 0.2190-inch thickness, this insert seats into compatible CoroThread 266 toolholders used in CNC turning and threading applications. Installation is performed by machinists and CNC operators working in precision threading operations.

This insert is intended for internal Acme thread production on CNC lathes and turning centers. The Acme thread form is common in power transmission components such as lead screws, jack screws, and linear actuators. The CoroThread 266 laydown style is suited for finishing passes on these thread forms where dimensional accuracy and surface finish are critical. The C chipbreaker geometry assists with chip control in ferrous and non-ferrous materials. This insert is sold individually with a minimum order quantity of 10 units.
