Kennametal 4119699 Milling Insert KCK15 Solid Carbide

Product Description

The KENNAMETAL 4119699 is a solid carbide milling insert with ISO designation HNPJ0604ANSNGD and ANSI code HNPJ43ANSNGD, engineered for high-productivity milling of cast iron workpieces. The insert features a hexagon shape with a 120-degree included angle and delivers 12 usable cutting edges per insert on a double-sided configuration, maximizing tool life between changeovers. A multilayer CVD coating system combining TiN, TiCN, and Al2O3 provides thermal resistance and wear protection suited to the abrasive nature of cast iron. The GD chip breaker geometry, chamfered and honed cutting edges, and negative rake angle contribute to edge strength and predictable chip control in interrupted and continuous milling operations. This insert is compatible with the Kennametal Dodeka cutter series.

This insert is intended for milling applications where the primary workpiece material is cast iron, corresponding to material grade K and material grade code C1. It is suited for face milling and shoulder milling operations in manufacturing environments where cast iron components such as engine blocks, housings, and machine bases are processed. Installation is performed by licensed machinists and toolroom professionals operating CNC machining centers or manual milling equipment. The neutral hand designation allows use in standard cutter bodies without left- or right-hand orientation constraints.

Key Features

• Solid carbide substrate with multilayer MTCVD coating: TiN, TiCN, and Al2O3 for cast iron wear resistance
• Hexagon insert shape with 120-degree included angle and 12 cutting edges per insert
• Double-sided insert design extends usable edge count and reduces cost per edge
• GD chip breaker with chamfered and honed cutting edges for controlled chip formation
• Negative rake geometry for improved edge strength in abrasive cast iron milling
• Screw-held mounting method compatible with Dodeka cutter series bodies

Compatibility

Designed for use with the Kennametal Dodeka cutter series. Conforms to ANSI and ISO insert standards with designations HNPJ43ANSNGD and HNPJ0604ANSNGD respectively. Optimized for primary workpiece material cast iron (material grade K, code C1).

Installation Notes

Insert seating and screw torquing should be performed by a qualified machinist following the cutter body manufacturer's tooling manual. Power down and lock out the machine spindle before changing inserts. Inspect the cutter body pocket and seating surfaces for wear or debris before installing a new insert. Do not exceed the cutter body's rated speed or feed parameters for the insert grade being used.
