Industrial DCMT070204 Carbide Turning Insert Lathe Cutting Blades

Description:

The DCMT070204 (DCMT21.51) Carbide Turning Insert is used in CNC lathes and manual turning machines for precision external and internal turning operations. Commonly installed in indexable lathe tool holders used for machining steel, stainless steel, cast iron, and non-ferrous materials in machine shops and manufacturing facilities. Machinists, maintenance teams, and machine shops use these inserts for production machining, tool replacement, and precision finishing applications.

Applications:

The DCMT070204 carbide turning insert is a positive-rake 55° diamond insert designed for light to medium-duty turning and finishing operations. It is commonly used in CNC lathes, turning centers, and engine lathes for facing, profiling, boring, and general turning of carbon steel, alloy steel, stainless steel, cast iron, and non-ferrous metals. The insert's positive 7° clearance angle reduces cutting forces and improves chip evacuation, making it suitable for precision machining applications.
