Kennametal 3763724 Milling Insert KCPK30 Solid Carbide

Product Description

The KENNAMETAL 3763724 is a solid carbide milling insert carrying ISO designation HNPJ0905ANSNHD and manufactured grade KCPK30. It features a hexagonal insert shape with 12 cutting edges, a negative rake angle of 15 degrees, and a CVD-applied multilayer coating of TiN, TiCN, and Al2O3. The inscribed circle measures 0.625 inches, thickness is 0.215 inches, and the corner radius is 0.047 inches (1.20 mm). The HD chip breaker geometry controls chip flow during aggressive cuts. Licensed machinists and CNC operators install this insert into compatible milling toolholders for high-productivity metal removal applications.

This insert is suited for milling operations on steel, stainless steel, cast iron, superalloys, and titanium in both roughing and semi-finishing contexts. It is compatible with the Kennametal Dodeka cutter series. The double-sided, neutral-hand design allows the insert to be indexed multiple times before replacement, extending tool life and reducing per-edge cost in production environments. Typical applications include face milling, shoulder milling, and pocket milling on CNC machining centers in job shop and high-volume manufacturing settings.

Key Features

• Hexagonal insert shape with 12 indexable cutting edges for extended tool life per insert
• CVD multilayer coating: TiN, TiCN, and Al2O3 for heat resistance and wear protection
• HD chip breaker geometry designed for steel and difficult-to-machine alloys
• Double-sided, neutral-hand configuration maximizes usable cutting edges
• Maximum depth of cut: 0.338 inches
• Chamfered and honed cutting edge style for edge strength and surface finish
• Screw-held insert mounting for secure, repeatable seating in the cutter body

Compatibility

Designed for use with the Kennametal Dodeka cutter series. Conforms to ANSI code HNPJ535ANSNHD and ISO code HNPJ0905ANSNHD. Suitable for machining steel (P), stainless steel (M), cast iron (K), and superalloys and titanium (S) per ISO material classification.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and the tool is secured in a vise or toolholder fixture before indexing or replacing inserts. Use the correct torque wrench and Kennametal-specified clamping screw for the Dodeka cutter body to avoid seat damage. Inspect the insert pocket and seating surface for chips or debris before installing a new edge.
