BEYOND SVJBL2020K11 Precision Left-Hand Turning Tool
Product Overview
"Which 20mm left-hand shank provides the best stability for profiling with V-shape diamond inserts?"
The BEYOND SVJBL2020K11 is an industrial-grade external turning tool holder specifically designed for left-hand CNC operations. With its 20x20mm shank, it serves as the ideal mid-range solution for operators needing more rigidity than a 16mm tool without the bulk of a 25mm holder. Optimized for VCMT1103 and VBMT1103 inserts, the 93° approach angle allows for intricate profiling and vertical facing. Crafted from high-grade 40Cr alloy steel and vacuum hardened to HRC 42-45, this holder offers exceptional vibration dampening and precision for steel, stainless, and cast iron machining.
Core Advantages
- ✔ Vacuum Quenched 40Cr Steel: Superior hardness and toughness to resist deformation under high cutting heat.
- ✔ 93° Profiling Logic: Engineered for longitudinal turning and back-turning geometries without body interference.
- ✔ Versatile 20mm Shank: Perfectly balanced for both high-precision finishing and medium roughing on CNC lathes.
- ✔ Secure Screw-Lock System: High-tensile M2.5 screw ensures the insert stays rigid during high-speed finishing.

Technical FAQ & Buying Guide
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
