Kennametal 5533526 Carbide Cutoff Insert 5mm Tiocn

Product Description

The KENNAMETAL 5533526 is a single-end carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. Manufactured under the Beyond Evolution series, this insert features a CVD-applied TiOCN coating over a KCU25 carbide substrate, delivering thermal resistance and wear life in demanding cut-off applications. It carries a 5mm (0.197 inches) cutting width, a 0.012-inch corner radius, a 2-degree relief angle, and a neutral lead angle with a CR chipbreaker geometry. The insert seat size is 5, and overall length measures 0.482 inches. Machinists and CNC operators install this insert into compatible parting blade toolholders as a direct replacement component.

This insert is suited for production turning environments where consistent part separation and groove profiling are required. The neutral hand orientation makes it appropriate for standard right-to-left infeed parting. The CR chipbreaker is optimized for chip control during straight cut-off operations on a range of workpiece materials. The KCU25 grade and CVD TiOCN finish position this insert for use on steel, alloy steel, and similar materials at moderate to high cutting speeds. It is a single-use, non-multi-use insert intended for professional machining applications.

Installation Notes

This insert is installed and replaced by machinists or CNC tooling technicians. Power down and lock out the machine spindle before changing inserts. Use the appropriate torque wrench or insert clamp tool specified by the toolholder manufacturer — do not overtighten by hand. Inspect the insert pocket and seating surface for debris or damage before seating the new insert.
