Kennametal 2226807 Milling Insert KCPK30 Solid Carbide

Product Description

The KENNAMETAL 2226807 is a solid carbide parallelogram milling insert designed for indexable milling operations in demanding metal-cutting applications. Manufactured to ISO code 4.21103R611 and offered in the KCPK30 grade, this insert features a multilayer CVD coating of TiN, TiCN, and Al2O3 applied over a solid carbide substrate. The coating stack delivers thermal resistance, wear resistance, and crater resistance in a single insert, making it well suited for interrupted cuts and high-feed passes. At 0.158 inches thick with an inscribed circle of 0.6252 inches and a maximum depth of cut of 0.3383 inches, it covers a practical range of roughing and semi-finishing operations across multiple workpiece materials.

This insert is intended for use in CNC milling applications targeting steel, stainless steel, cast iron, superalloys, and titanium workpiece materials, covering material grade codes P, M, K, and S. It fits the KENNAMETAL 4.21103 series toolholders and is a single-sided insert, meaning each edge is presented once before the insert is indexed or discarded. Machinists and toolroom technicians working in production shops, job shops, and aerospace manufacturing environments will recognize the KCPK30 grade as a general-purpose CVD grade balanced for toughness and wear life across this broad material range.

• Maximum depth of cut of 0.3383 inches supports roughing passes
• Single-sided design ensures consistent edge presentation and simplified indexing
• Compatible with primary workpiece materials including steel, stainless steel, cast iron, superalloys, and titanium

Compatibility

Designed for use in KENNAMETAL 4.21103 series milling toolholders accepting insert size code 611 with an inscribed circle of 0.6252 inches. Compatible with material grades C1, C5, and C6 application categories.

Installation Notes

Milling inserts should be installed by a qualified machinist or toolroom technician following the toolholder manufacturer's torque specifications for the appropriate clamping screw. Always power down and lock out the machine spindle before indexing or replacing inserts. Inspect the toolholder pocket and clamping hardware for wear or debris before seating a new insert. Do not mix insert grades or sizes within the same cutter body.
