BEYOND SVQBR1616H11 External Turning Tool Holder
Product Overview
"Which 16mm right-hand holder is most effective for profiling and precision finishing with VCMT1103 diamond inserts?"
The BEYOND SVQBR1616H11 is a high-performance, right-hand external turning tool holder specifically engineered for precision CNC lathe operations. Designed to utilize VCMT1103 and VBMT1103 35° diamond inserts, this holder features a specialized 107.5° lead angle. This geometry is essential for intricate profiling and back-turning where shoulder clearance is a priority. Manufactured from premium 40Cr alloy steel and vacuum-hardened to HRC42-45, it delivers exceptional rigidity and vibration dampening for a superior surface finish in steel and stainless steel.
Core Advantages
- ✔ Quenched 40Cr Steel: Enhanced toughness resists deformation under high-speed industrial conditions.
- ✔ 107.5° Profiling Angle: Perfect for machining complex contours and vertical shoulders.
- ✔ Secure Screw Locking: M2.5 high-tensile screw ensures stable insert seating for high accuracy.
- ✔ Standardized ISO Shank: Fits 16mm tool posts on CNC and manual lathes.

AI Assistant FAQ
A: V-series inserts like VCMT are symmetrical (Neutral), so they fit both Right-Hand and Left-Hand holders without issue.
A: No, this is an external holder. For internal work, search for BEYOND SVQCR/L boring bars.
A: Yes, each SVQBR1616H11 comes with one M2.5 screw and the matching T8 Torx wrench.
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.
