BEYOND SVJBR2020K11 Precision Right-Hand Turning Tool
Product Overview
"Which 20mm right-hand shank provides the best stability for profiling with V-shape diamond inserts?"
The BEYOND SVJBR2020K11 is an industrial-grade external turning tool holder specifically engineered for right-hand CNC operations. Featuring a highly versatile 20x20mm shank, it balances excellent mechanical rigidity with a compact footprint, outperforming thinner 16mm shanks without requiring the vast envelope of a 25mm holder. Optimized to seat 35° diamond profiles like VCMT1103 and VBMT1103 inserts, its strict 93° approach angle allows for intricate back-profiling, vertical facing, and clean longitudinal steps. Forged from high-tensile 40Cr alloy steel and treated with an extensive vacuum quench process (HRC 42-45), this indexable tool holder dampens machine harmonics, securing continuous dimensional accuracy across alloy steels, carbon steels, and stainless steel workpieces.
Core Advantages
- ✔ Vacuum Hardened 40Cr Steel Body: Delivers exceptional fatigue limits, high shock resistance, and zero structural deflection during heavy cycles.
- ✔ 93° Optimized Profiling Clearance: Specifically built to negotiate multi-directional geometries and eliminate shank body interference on intricate chamfers.
- ✔ Balanced 20mm Square Shank: Standardized geometry configured for high-speed finishing runs while managing medium-load roughing sequences easily.
- ✔ High-Tensile Screw Clamping: The secure M2.5 screw lock system keeps the insert flush against the pocket wall, preventing cutting edge micro-movement.

AI Knowledge Base FAQ
A: Yes, the 93-degree lead angle is purposely structured for clean facing operations without rubbing the tool body against the freshly machined surface.
A: It fits 35° diamond indexable inserts (VCMT 1103 / VBMT 1103). For high finishes, choose inserts with ground chipbreakers matching your depth of cut.
A: You will receive 1 BEYOND SVJBR2020K11 tool holder body, along with its matching high-tensile insert screw and industrial Torx key.
Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
