SVJCR 2020K11 External Turning Tool Holder

The SVJCR 2020K11 is a high-precision external turning tool holder designed for profiling, finishing, and fine turning applications on CNC and conventional lathes. It is engineered to hold VCMT carbide inserts with a 35° diamond geometry, making it ideal for intricate profiling, machining tight angles, and achieving high-quality surface finishes.

With a 20×20 mm shank and right-hand cutting orientation, this tool holder provides rigidity and vibration resistance, ensuring smooth operation even under demanding machining conditions. The SVJCR pocket design ensures secure insert clamping and accurate alignment, improving consistency, chip evacuation, and tool life. The 93° approach angle makes it particularly effective for profiling and finishing, while allowing excellent accessibility in narrow spaces.

The SVJCR 2020K11 is widely used in automotive, aerospace, and precision engineering industries where fine detail, accuracy, and repeatability are essential. When paired with VCMT 1103 inserts, it is best suited for finishing and semi-finishing operations on steels, stainless steels, and alloy materials.
