Kennametal 3556375 Milling Insert HNGJ090543ANSNHD KCPK30

Product Description

The KENNAMETAL 3556375 is a solid carbide milling insert identified by ISO code HNGJ090543ANSNHD and manufactured in grade KCPK30. This double-sided, hexagon-shaped insert features 12 cutting edges and carries a CVD-applied multilayer coating of TiN, TiCN, and Al2O3. It is designed for indexable milling operations across a range of demanding workpiece materials and fits Kennametal Dodeka cutter series toolholders. The neutral hand orientation and negative rake geometry make it suitable for high-stability, interrupted-cut applications. Installation is performed by machinists and CNC tooling technicians during scheduled insert indexing or replacement cycles.

This insert is intended for milling steel, stainless steel, cast iron, superalloys, and titanium, covering material grades P, M, K, and S. The HD chip breaker geometry is optimized for aggressive material removal in these categories. It is suited for both roughing and finishing passes where edge security and coating durability are priorities. The double-sided design with 12 usable cutting edges extends tool life per insert, making it a practical choice for production milling environments.

Key Features

• Double-sided hexagon insert with 12 cutting edges for extended tool life per unit
• CVD multilayer coating: TiN, TiCN, and Al2O3 for wear resistance and thermal stability
• KCPK30 grade suitable for steel, stainless steel, cast iron, superalloys, and titanium
• HD chip breaker geometry for controlled chip formation in demanding cuts
• Negative rake angle with chamfered and honed cutting edge style for edge strength
• Screw-held mounting in Kennametal Dodeka cutter series

Compatibility

Designed for use in Kennametal Dodeka series indexable milling cutters. Insert conforms to ANSI code HNGJ53511ANSNHD and ISO code HNGJ090543ANSNHD. Compatible with toolholders accepting HNGJ series inserts with a 0.625 inch inscribed circle.

Installation Notes

Insert replacement and indexing should be performed by a qualified machinist or CNC tooling technician with the spindle fully stopped and machine in a locked-out, tagged-out state. Use the appropriate Torx or hex key as specified by the toolholder manufacturer when tightening the clamping screw. Inspect the insert pocket seat and screw for wear or debris before seating a new insert. Do not exceed the cutter body's rated speed and feed parameters for the installed insert geometry.
