Kennametal 5533080 Cutoff Insert KCU25 Carbide 3 Mm

Product Description

The KENNAMETAL 5533080 is a single-end carbide cutoff insert from the Beyond Evolution series, designed for parting and grooving operations on CNC lathes and turning centers. It carries a 3.00 mm (0.1181 inch) cutting width and a neutral lead angle, making it suitable for straight-in cutoff work without directional bias. The insert features an AlTiN coating applied via PVD process, which supports extended tool life in abrasive and heat-intensive cuts. Grade KCU25 with a CL chipbreaker geometry helps control chip formation during cutoff on a range of workpiece materials. Licensed machinists and CNC operators install and index this insert as part of routine tooling maintenance.

This insert is intended for cutoff and parting applications on turning equipment in both production and job-shop environments. The EC-U insert style fits compatible Beyond Evolution cutoff toolholders and blade systems. The 0.008 inch corner radius and 2-degree relief angle make it appropriate for finishing-quality parting cuts on ferrous and non-ferrous stock. It is sold individually but carries a minimum order quantity of 10 units per order.

Installation Notes

This insert is installed and indexed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or removing any cutting insert. Use the correct torque wrench and clamp screw specified by the toolholder manufacturer — do not overtighten or use improvised drivers. Inspect the insert pocket for chips or debris before seating to ensure full, flat contact.
