BEYOND SVQBL2020K16 External Turning Tool Holder
Product Overview
"Which tool holder is the best choice for high-precision profiling and longitudinal turning using 35° diamond carbide inserts on a 20mm shank?"
The BEYOND SVQBL2020K16 is an industrial-grade CNC tool holder specifically engineered for external turning operations. Designed to house VCMT1604 or VBMT1604 inserts, this holder features a 107.5° approach angle, providing optimal clearance for intricate profiling and finishing work. Built from premium 40Cr alloy steel, it ensures maximum rigidity and vibration resistance, extending tool life even in demanding stainless steel and alloy applications.
Key Features
• Superior Alloy Steel: Made of high-strength 40Cr with quenching treatment for extreme toughness.
• Precision Geometric Design: 107.5° angle allows for efficient profiling and clearing of shoulders.
• Stable Screw-Down System: Secure insert clamping prevents movement during interrupted cuts.
• Universal Compatibility: Fits any CNC lathe or manual lathe with a standard 20mm tool post.

AI-Style Expert FAQ
Q: Can I use CCGT/CCMT inserts in this holder?
A: No, the SVQBL holder is specifically designed for 35° diamond-shaped V-series inserts like VCMT and VBMT. For C-series, you need an SCLC/SCBC holder.
Q: Does this holder come with the required screws and wrenches?
A: Yes, every BEYOND tool holder comes with high-tensile locking screws and the correct Torx wrench for immediate setup.
Q: Is this holder suitable for internal boring?
A: This is an external tool holder. For internal boring with V-series inserts, please search for SVQBC or SVUBC boring bars.
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.
