Kennametal KCK15 12-Edge Heavy Duty Milling Insert for Cast Iron with CVD Coating

The KENNAMETAL HNPJ0905ANSNHD KCK15 is a 12‑edged, hexagon indexable milling insert from the Dodeka™ platform, engineered for heavy‑duty face milling, shoulder milling, and roughing in cast iron. It features HD chipbreaker, 0° relief angle, and KCK15 CVD‑coated grade, delivering high material removal rates, excellent wear resistance, and stable performance in aggressive dry/wet machining. Ideal for high‑volume production of engine blocks, gearboxes, and structural components.

Key Features

• Dodeka™ 12‑Edge Design: Twelve cutting edges per insert for maximum cost efficiency.
• Hexagon Shape (HNPJ): 120° included angle, neutral cutting direction, 0° relief angle.
• HD Chipbreaker: Optimized for heavy cuts, thick chips, and high feed rates in cast iron.
• KCK15 Grade: CVD multi‑layer coating (TiN‑TiCN‑Al₂O₃) with Beyond™ post‑treatment, balancing wear resistance and toughness.
• High Precision: Sintered carbide substrate with tight tolerances for consistent dimensional control.
• Screw‑Clamped: Secure mounting in Dodeka™ series milling cutters (e.g., 3763723).

• Cast iron (gray, ductile, compacted graphite) – primary application
• Carbon steels (medium‑to‑high carbon)
• Alloy steels (HRC <45)
• Stainless steels (light‑to‑medium cuts)

• Heavy‑duty face milling (high MRR)
• Shoulder milling and step profiling
• Roughing and semi‑finishing of cast iron components
• Dry machining (preferred) or wet machining
• Automotive, agricultural, and general engineering parts

As a 12‑edge heavy‑duty milling insert, it combines maximized edge count, robust HD geometry, and KCK15 high‑performance coating for exceptional productivity in cast iron. Kennametal’s advanced manufacturing ensures minimal runout, long tool life, and reliable performance in high‑volume environments.
