Sandvik Coromant 5754446 Turning Insert TNMG433KR 3210

Product Description

The SANDVIK COROMANT 5754446 is a TNMG433KR 3210 series turning insert designed for indexable tooling systems in CNC turning operations. It features a 60-degree triangular shape with a neutral hand orientation and a multi-layer coating of TiCN, Al2O3, and TiN applied over a solid carbide substrate. The insert measures 22 millimeters in length with a 0.5 inch (12.70 mm) inscribed circle and a 3/64 inch (1.20 mm) corner radius. The KR chip breaker geometry is engineered for controlled chip formation. This insert is installed by machinists and CNC turning specialists in production and job-shop environments.

This insert is built for turning cast iron workpieces, consistent with its K-series primary workpiece material designation. It fits within the T-Max P series tooling system and is held in place using a clamp and pin method. Typical applications include external turning passes requiring a maximum depth of cut up to 0.8189 inch (20.80 mm). The ISO code for this insert is TNMG 22 04 12-KR 3210, which is useful for cross-referencing with tooling catalogs and machine setup sheets. The insert delivers six usable cutting edges per unit.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Always power down and lock out the machine before indexing or replacing inserts. Use the appropriate torque wrench or insert key per toolholder manufacturer specifications — do not overtighten the clamping screw. Inspect the toolholder pocket and seating surface for debris or wear before seating the new insert.
