Sandvik Coromant 5735688 Threading Insert Un 14 Tpi

Product Description

The SANDVIK COROMANT 5735688 is a carbide threading insert designed for internal UN thread cutting applications. Part of the CoroCut MB series, this right-hand insert features a TiAlN/TiN finish applied via PVD coating, which improves wear resistance and tool life during threading operations on CNC lathes and turning centers. It carries manufacturer grade 1025 and an included angle of 60 degrees, making it suited for standard unified national thread profiles. Machinists and CNC operators working in production or job-shop environments rely on inserts like this for repeatable, accurate internal thread generation across a range of materials.

This insert is built for internal threading at 14 threads per inch (TPI) to the UN thread standard. The MB07 insert size and right-hand orientation make it compatible with CoroCut MB toolholders configured for internal threading. It is typically used in turning centers and CNC lathes for threading bores in components such as hydraulic fittings, fastener bodies, and machined housings. Production machinists and tool-room operators are the primary users of this insert in both high-volume and precision low-volume machining environments.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and all motion is locked out before changing inserts. Seat the insert fully in the toolholder pocket and secure with the appropriate clamping screw to the toolholder manufacturer torque specification. Verify insert orientation and thread profile match the programmed toolpath before resuming cutting operations.
