Kennametal 6165759 HNPJ0604ANSNGD KCSM40 Milling Insert

Product Description

The KENNAMETAL 6165759 is a solid carbide milling insert identified by ISO code HNPJ0604ANSNGD and manufactured to grade KCSM40. The insert features a hexagon shape with 12 cutting edges, making it a high-utilization double-sided insert suited for productive face and shoulder milling operations. A TiAlN and TiN multilayer coating applied via PVD process provides thermal resistance and wear protection at elevated cutting temperatures. The insert has a neutral hand orientation, a negative rake geometry, and chamfered and honed cutting edges for controlled chip formation. Thickness measures 0.1750 inches with an inscribed circle diameter of 0.4724 inches and a 1.00 mm (0.0394 inches) corner radius. Licensed machinists and CNC tooling technicians install this insert in compatible Kennametal Dodeka cutter bodies.

This insert is engineered for milling steel, stainless steel, superalloys, and titanium, corresponding to ISO material groups P, M, and S. It is appropriate for both roughing and semi-finishing passes where controlled chip breaking is required. The GD chip breaker geometry is optimized for these demanding workpiece materials. Maximum depth of cut is 0.2533 inches. The insert is held by screw clamping and is suited to high-productivity CNC milling centers in job shop, aerospace, and general metalworking environments where tool life and edge count per insert are critical cost factors.

Key Features

• Hexagon insert shape with 12 usable cutting edges maximizes cost per edge
• Double-sided design for increased tool life per insert
• TiAlN and TiN PVD multilayer coating for high-temperature wear resistance
• GD chip breaker optimized for steel, stainless steel, superalloys, and titanium
• Negative rake with chamfered and honed edge preparation for edge strength
• Meets ANSI and ISO standards; ANSI code HNPJ43ANSNGD, ISO code HNPJ0604ANSNGD

Compatibility

Designed for use with Kennametal Dodeka cutter series bodies that accept HNPJ-style screw-clamped inserts. Verify seat geometry and screw torque specifications in the applicable Kennametal Dodeka toolholder documentation before installation.

Installation Notes

Installation is performed by qualified CNC tooling technicians or machinists. Disengage machine power and ensure the spindle is fully stopped before indexing or replacing inserts. Use the correct Torx or hex key specified by the cutter body manufacturer to seat the clamping screw — do not overtighten or substitute fasteners. Inspect the insert pocket and clamping screw for wear or debris before seating each new insert to ensure proper seating and runout.
