BEYOND S16Q-SVQBR11 Indexable Internal Right-Hand Boring Bar (Fits VBMT 1103)
1. Product Overview
"Which 16mm right-hand boring bar provides optimal vibration damping and clearance for finish-profiling with VBMT 1103 inserts?"
The BEYOND S16Q-SVQBR11 is a high-rigidity internal boring bar engineered for industrial-grade CNC turning. Featuring a high-tensile steel shank, it is designed to mitigate harmonic vibration in small-to-medium bore applications. The 107.5° lead angle (SVQBR geometry) offers superior back-boring capability, while the 7° positive clearance pocket ensures stable seating and efficient chip evacuation when paired with standard VBMT 1103 rhombic inserts.
2. Key Features
- Rigid 16mm Steel Shank: Minimizes deflection during deep-bore internal operations.
- 107.5° SVQBR Geometry: Ideal for complex profiling and shoulder relief.
- Secure Screw Clamping: Guarantees perfect insert indexing and repeatability.
- Industrial Finish: Black oxide coating for enhanced wear and thermal resistance.

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.
