Kennametal 2616310 Milling Insert WPMT080615ZZERGP KC522M

Product Description

The KENNAMETAL 2616310 is a solid carbide trigon milling insert with ANSI/ISO designation WPMT080615ZZERGP, manufactured in grade KC522M with a PVD-applied TiAlN coating. Designed for indexable milling operations, this single-sided insert features a positive rake geometry with a 30-degree rake angle, an 11-degree relief angle, and a honed cutting edge style. Three cutting edges per insert are available on the right-hand configuration, and a GP chip breaker geometry supports chip control across a range of depths of cut. The insert is held in the cutter body by screw clamping and is compatible with KSWM series cutter platforms. At 0.25 inches thick and weighing 0.0208 pounds, it is a compact insert suited for finishing and semi-finishing work on a variety of workpiece materials.

This insert is rated for use on steel, stainless steel, cast iron, superalloys, and titanium, covering material application codes P, M, K, and S per ISO classification. The KC522M grade with TiAlN PVD coating provides wear resistance and thermal stability at elevated cutting speeds, making it appropriate for high-productivity milling applications in aerospace, general machining, and job-shop environments. It is installed by qualified machinists or tooling technicians in CNC or manual milling setups requiring a WPMT-style insert seat.

Key Features

• Solid carbide construction with PVD TiAlN coating for extended tool life on ferrous and exotic workpiece materials
• Trigon (60-degree included angle) insert shape with three usable cutting edges per insert
• Positive rake geometry (30-degree rake angle) reduces cutting forces on difficult materials
• Honed cutting edge style for improved edge strength and reduced chipping risk
• GP chip breaker designed for reliable chip control in steel and stainless steel milling
• Right-hand cutting orientation; screw-clamped insert holding method

Compatibility

Designed for use with KSWM series Kennametal milling cutter bodies that accept WPMT-style insert seats. ANSI and ISO designation WPMT080615ZZERGP confirms seat and geometry compatibility.

Installation Notes

Installation and indexing of milling inserts should be performed by qualified tooling technicians or machinists with the spindle fully powered down and the machine in a locked-out, tagged-out state per applicable OSHA and shop safety procedures. Use the correct torx or hex key as specified by the cutter body manufacturer to achieve the proper seating torque for the screw-clamp holding method — do not overtighten or substitute fasteners. Inspect the insert pocket for debris, damage, or wear before seating a new insert. Confirm insert orientation matches the right-hand cutting direction before resuming operation.
