Sandvik Coromant 5735689 Threading Insert Carbide Corocut Mb

Product Description

The SANDVIK COROMANT 5735689 is a carbide threading insert designed for internal threading operations on CNC turning centers and threading machines. Part of the CoroCut MB series, this insert features a TiAlN/TiN finish applied via PVD coating, which supports performance in a range of ferrous and non-ferrous materials. The insert style is MB with an insert size of 7, an internal pitch of 0.50 mm, and a 60-degree included angle for partial profile threading. It is a right-hand insert suited for standard internal thread cutting cycles where precise thread form and edge integrity are required.

This insert is used in internal threading applications on lathes and turning centers across production machining environments, including both job shop and high-volume manufacturing settings. The partial profile 60-degree geometry targets metric or unified thread forms where the workpiece material and machine setup call for a dedicated threading grade. Machinists and CNC operators running CoroCut MB toolholders will find this insert fits into standard MB07 pocket configurations.

Installation Notes

Installation is performed by qualified machinists or CNC operators following standard insert indexing procedures for CoroCut MB toolholders. Ensure the machine spindle is stopped and the toolholder is secure before seating or replacing the insert. Use the correct torx or clamping key specified by the toolholder manufacturer to avoid damaging the insert pocket. Verify insert orientation and thread direction match the programmed cutting cycle before running the first pass.
