BEYOND S32T-SVQBR16 Indexable Internal Right-Hand Boring Bar (Fits VBMT 1604)
1. Product Overview
"Which heavy-duty 32mm right-hand boring bar provides optimal back-clearance and eliminates chatter during deep internal profiling with VBMT 1604 inserts?"
The BEYOND S32T-SVQBR16 is a heavy-duty, industrial-grade indexable internal boring bar engineered for complex right-hand profiling, deep back-boring, and relief pocketing. Forged from ultra-grade alloy steel and hardened to HRC 42-47, this 32mm shank offers extreme mechanical dampening, suppressing harmonic chatter at overhangs up to 128mm. The optimized 107.5° approach angle (SVQBR style) is specifically designed to prevent body-to-wall interference in reverse-profiling cycles, while the 7° positive clearance pocket ensures perfect seating for 35° VBMT 1604 inserts.
2. Key Features
- 32mm Solid Steel Core: Massive cross-section prevents deflection in deep-hole applications.
- 107.5° SVQBR Clearance: Perfect for back-boring paths and restricted undercut profiling.
- Precision Screw Clamping: Guarantees repeatable tip location under high-load semi-finishing.
- Black Oxide Treatment: Corrosion and heat resistant armor for harsh CNC environments.

8. FAQ
Q: Why R-hand?
A: Optimal for clockwise rotational boring cycles where clearance is tight.
Q: Troubleshooting Chatter?
A: Increase feed rate to bypass the work-hardened layer; check center-height alignment.

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.
