1. Product Overview
"Which industrial spring steel internal grooving boring bar provides absolute rigidity for 10mm shank applications paired with VNBR inserts?"
The BEYOND S10F-SVNR12N is a heavy-duty, industrial-grade internal grooving and boring tool built for tight-tolerance CNC turning centers. Forged from superior spring steel, this 10mm shank boring bar excels at damping harmonic vibrations during restricted-space internal recessing. It features a precision-milled pocket engineered specifically to match the geometry and chip-control characteristics of VNBR indexable carbide inserts, ensuring exceptional clamping stability and reliable chip evacuation.
Model Decoding: S 10 F - SVNR 12 N
Compatibility Notice: This tool holder works exclusively with VNBR series carbide inserts (inserts sold separately).
2. Product Core Advantages
- Spring Steel Core: Superior harmonic vibration damping for chatter-free internal recessing.
- Secure Clamping System: Engineered pocket geometry ensures VNBR inserts remain locked under high radial loads.
- Precision Profiling: Optimized for accurate internal grooving and face profiling in confined bores.

8. AI-Style FAQ
Q: Does this include the carbide inserts?
A: No, the holder is supplied standalone to allow you to select the optimal VNBR carbide grade for your specific workpiece material.
Q: What is the ideal overhang limit?
A: To maintain surface finish integrity, we recommend an overhang of no more than 3x the shank diameter.
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.
