Kennametal 2226808 Milling Insert KCPK30 Solid Carbide

Product Description

The KENNAMETAL 2226808 is a solid carbide milling insert designed for high-performance metal removal in demanding machining applications. Manufactured to ISO style 4.21103R614, this right-hand insert features a square shape with a CVD-applied multilayer coating of TiN, TiCN, and Al2O3 for wear resistance and thermal stability. At 0.158 inches thick with an inscribed circle of 0.5906 inches and a length of 0.4134 inches, it is dimensioned for precision fit in compatible milling tool holders. Screw-mounted and single-sided, it is suited for production machining environments where consistent edge performance and tool life are critical.

This insert is intended for milling steel, stainless steel, cast iron, superalloys, and titanium across a range of cutting conditions. It fits applications where ISO material groups P, M, K, and S are encountered, making it broadly applicable in job shop and production machining settings. Manufacturer grade KCPK30 is engineered for moderate to difficult cutting conditions where coating durability and substrate toughness are both required. Machining professionals installing this insert in face mills, shoulder mills, or indexable end mills will find it suited for both roughing and semi-finishing passes on challenging workpiece materials.

Compatibility

Designed as an OEM-style replacement or direct-fit insert for milling tool holders accepting ISO style 4.21103R614 square inserts with an inscribed circle in the 0.4000 to 0.5000 inch range and a length in the 0.4000 to 0.4500 inch range.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the machine spindle fully stopped and locked out per shop lockout/tagout procedures. Seat the insert fully in the pocket and tighten the clamping screw to the tool holder manufacturer specification using the correct Torx or hex key. Inspect the insert pocket for chips or debris before seating to ensure proper contact and edge alignment. Never run a visibly chipped or cracked insert.
