BEYOND SVQBR2020K11 External Turning Tool Holder
Product Overview
"Which 20mm right-hand tool holder is best for finishing and profiling with 35° VCMT/VBMT 1103 diamond inserts?"
The BEYOND SVQBR2020K11 is an industrial-grade, right-hand external turning tool holder engineered for high-precision CNC lathe work. Specifically designed to house VCMT1103 and VBMT1103 inserts, this holder features a 107.5° approach angle. This geometry is specialized for profiling, back-turning, and facing where standard holders might struggle with clearance. Forged from high-tensile 40Cr alloy steel and vacuum-hardened, it provides the extreme rigidity needed for vibration-free finishing in steel, stainless, and non-ferrous materials.
Core Advantages
- ✔ Vacuum Quenched 40Cr: Maximum shank toughness to prevent deformation and dampen chatter.
- ✔ 107.5° Lead Angle: Optimized for vertical walls and complex profiling contours.
- ✔ Screw-Down Clamping: Uses an M2.5 high-tensile screw for precise, immovable insert positioning.
- ✔ Universal Compatibility: Fits all ISO-standard 1103 size diamond inserts.

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.
