Product Description

The SANDVIK COROMANT 5961303 is a solid carbide grooving insert designed for threading and grooving operations in the CoroThread 266 series. It carries a TiCrAlN/TiN coating applied via PVD process, delivering wear resistance and extended tool life in demanding turning applications. The insert features a 1.3 mm cutting width, a maximum depth of cut of 1.6 mm, and a neutral rake angle, making it suited for precise, controlled grooving passes on a lathe. Machinists and CNC turning specialists install this insert into compatible CoroThread 266 toolholders for right-hand cutting operations.

This insert is used in CNC turning centers and manual lathes performing external threading and grooving operations. The 1135 manufacturer grade and PVD-applied TiCrAlN/TiN finish make it appropriate for cutting a range of workpiece materials where consistent chip control and dimensional accuracy are required. The C chip breaker geometry supports reliable chip evacuation during shallow grooving passes. It is sold individually with a minimum order quantity of 10 units.
