SDJCR 2020K07 External Turning Tool Holder

The SDJCR 2020K07 is a robust external turning tool holder designed for precision turning, profiling, and finishing operations on CNC lathes and conventional machines. It is specifically engineered to hold DCMT carbide inserts, providing high stability, accuracy, and long tool life in demanding machining environments.

With a 20×20 mm shank size and right-hand cutting orientation, the holder ensures rigidity and reduces vibration during cutting, resulting in smooth surface finishes and consistent dimensional accuracy. Its SDJCR-style clamping pocket secures the insert firmly, enabling reliable chip evacuation and stable performance in both continuous and light interrupted cuts.

The SDJCR 2020K07 is widely applied in industries such as general machining, automotive, aerospace, and mold-making, where versatility and repeatability are essential. When paired with DCMT inserts, it delivers excellent performance in semi-finishing and finishing of steels, stainless steels, and other alloys.
