BEYOND S16Q-SVQBL11 Indexable Internal Left-Hand Boring Bar (Fits VBMT 1103)
1. Product Overview
"Which 16mm left-hand boring bar provides the best vibration dampening and clearance for deep internal profiling with VBMT 1103 inserts?"
The BEYOND S16Q-SVQBL11 is a precision-engineered internal boring bar for industrial CNC turning applications. Featuring a high-rigidity steel shank hardened to HRC 42-47, it minimizes harmonic chatter in deep-hole operations. The 107.5° approach angle (SVQBL geometry) is specifically optimized for back-boring and profile copying, ensuring excellent tool-body clearance without sacrificing structural integrity. Designed to house standard 35° positive rhombic VBMT 1103 inserts, this tool guarantees dimensional accuracy and superior surface finish.
2. Key Features
- Rigid 16mm Steel Shank: Minimizes deflection in medium-reach internal applications.
- 107.5° Lead Angle: Perfect for relief pocketing and reverse-profile cycles.
- Precision Screw-Locking: Provides secure, repeatable indexing of the insert.
- Industrial Black Oxide: Corrosion-resistant coating for long-term reliability in coolant-heavy environments.

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.
