RCMT1204MO 4325 Sandvik Round Carbide Insert For Heavy Duty Steel Machining

RCMT1204MO 4325 High-Strength Round Turning Insert | Sandvik Insert for Heavy-Duty Steel Machining

The RCMT1204MO 4325 is a high-strength round turning insert from Sandvik Coromant, engineered for reliable and efficient metal cutting. Featuring the versatile 4325 carbide grade, this insert delivers excellent wear resistance and thermal stability, making it ideal for roughing to semi-finishing of steel (ISO P), as well as light-duty machining of stainless steel and alloy steels.

The MO chip-breaker (Medium Operation) ensures smooth cutting action, efficient chip evacuation, and stable performance even under varying cutting conditions. The round insert geometry offers superior edge strength and exceptional resistance to chipping, enabling the insert to handle heavy-duty cuts, interrupted turning, and high-impact operations with ease.

Key Features
