Sandvik Coromant 5753325 Threading Insert Carbide Tialn

Product Description

The SANDVIK COROMANT 5753325 is a carbide threading insert in the Top Lok series, designed for both internal and external thread cutting operations. Finished with a TiAlN PVD coating, this insert delivers heat and wear resistance suited to production threading in steel, stainless, and similar materials. It covers a pitch range of 0.70 to 3.50 mm (7 to 36 TPI) and is ground to a 60-degree V thread form with a right-hand cutting orientation. Insert size 2 with a tip-to-top height of 0.219 inches (5.56 mm) and a corner radius of 0.004 inches (0.10 mm). Installed by machinists and toolroom technicians on CNC lathes and threading attachment setups.

This insert is applicable to both internal and external threading in a single grade, reducing the number of grades required on the floor. The 0.70 to 3.50 mm pitch range covers the most common metric and unified thread pitches encountered in general machining, making it a practical choice for job shops and production environments running mixed threading work. The Top Lok insert style is designed for use in compatible Top Lok toolholders and boring bars where secure, repeatable insert indexing is required.

Installation Notes

Threading inserts must be seated fully and locked securely in the pocket before initiating any cut; a loose insert will chip immediately under threading loads. De-energize and lock out the machine before indexing or replacing inserts. Use the correct torque wrench or key specified by the toolholder manufacturer when tightening the clamping screw. Inspect the insert pocket and clamping surfaces for chips or debris before seating a new insert to maintain accurate repeatability.
