Product Description

The SANDVIK COROMANT 5757917 is a carbide threading insert designed for external thread cutting applications. It belongs to the CoroThread 266 series and is manufactured to grade 1125 with a PVD coating process. The insert follows a Partial Profile 55-degree thread standard with a 60-degree included angle, making it suited for cutting threads in the 14-28 TPI range. It is a right-hand insert and carries an ISO code of 266RG16VW01A001M1125. Machining professionals and CNC operators install this insert into compatible CoroThread 266 toolholders for precision thread turning on external workpiece features.

This insert is intended for external threading operations on CNC lathes and turning centers. The CoroThread 266 series is a modular threading system commonly used in production machining environments, including general metalworking shops handling a range of ferrous and non-ferrous materials. The 14-28 TPI capability covers a broad range of standard unified and similar thread forms. The grade 1125 carbide substrate with PVD coating supports consistent thread quality and insert life across medium to high production runs.
