The SANDVIK COROMANT 5782018 is a solid carbide laydown threading insert designed for internal UN thread cutting at 11 threads per inch. Part of the CoroThread 266 series, it features a TiCrAlN/TiAlN PVD coating that improves wear resistance and extends tool life in threading applications. The insert uses a right-hand cutting orientation and has an inscribed circle of 0.375 inches with a thickness of 0.1563 inches. It is sized for use with compatible 266-series toolholders and is installed by machinists and toolroom technicians working on CNC lathes and turning centers where precise internal thread geometry is required.
This insert is suited for internal UN thread profiles in precision machining environments, including production shops and job shops handling ferrous and non-ferrous materials. The 60-degree included angle and single-tooth design make it appropriate for generating clean thread forms in through-holes and blind bores. The CoroThread 266 platform is commonly used in industries where consistent thread quality and repeatable insert indexing are priorities. The insert ships individually and is subject to a minimum order quantity of 10 units.
Designed for use with SANDVIK COROMANT CoroThread 266 series toolholders that accept 266RL insert style, size code 16. Specific holder compatibility should be confirmed against the CoroThread 266 product line documentation. Do not install in toolholders not rated for this insert style and size.
Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before seating or indexing the insert. Confirm the insert is fully seated in the pocket and the clamping screw is torqued according to the toolholder manufacturer specifications before resuming cutting operations. Inspect the insert edge condition and coating integrity before each use.
