DNMG150604-PM 4325 Carbide Cutting Tools, Turning inserts,Wear resistant inserts

Engineered for excellence by Coromant, the DNMG150604-PM 4325 turning insert stands as a premium solution for precision machining of steel and cast iron components. This 55° diamond-shaped insert combines advanced material technology with optimized geometry to deliver exceptional wear resistance, consistent cutting performance, and extended tool life—making it an ideal choice for high-efficiency finishing and semi-finishing operations in automotive, aerospace, and general engineering industries.

• Triple-Layer CVD Coating: The TiCN+Al₂O₃+TiN coating stack provides superior thermal stability (up to 900°C) and wear resistance. The alumina layer features single-crystal orientation technology, significantly reducing flank wear during high-speed machining.
• Optimized Chip Breaker (PM槽型): The PM chip breaker geometry ensures efficient chip control, preventing chip entanglement and improving surface finish quality (Ra ≤ 0.8 μm) for precision components.
• High-Strength Carbide Substrate: The 4325 grade substrate offers excellent toughness and抗塑性变形能力, making it suitable for both continuous and light interrupted cutting operations.
• Cost-Effective Design: With 4 cutting edges and extended tool life, the insert reduces tool change frequency and overall machining costs.

Ideal for machining a wide range of steel and cast iron workpieces, including:

• Automotive components (crankshafts, camshafts, gear blanks)
• Hydraulic parts (valves, cylinders)
• General engineering structural parts
• Cast iron housings and brackets
