BEYOND S10K-SDXCR07 Internal Boring Bar & CNC Lathe Turning Tool Holder
1. Product Overview
Engineers Search: "Which right-hand internal boring bar maximizes chip evacuation stability during deep 10mm shank indexable turning?"
The BEYOND S10K-SDXCR07 is an industrial-grade, solid steel screw-on internal boring bar specifically engineered for right-hand (R) CNC lathe ID profiling, step boring, and precision finishing. Built to mitigate the common industry issues of vibration and tool deflection, this tool holder features a precision-machined insert pocket configured for standard 55° diamond DCMT0702 carbide inserts. By pairing the rigid alloy steel shank with highly engineered chipbreaker insert configurations, this system ensures flawless chip control, optimized cutting forces, and excellent surface finishes in demanding manufacturing cycles.
2. Product Core Features
- High-Tensile Spring Steel Construction: Quenched and tempered to HRC 42-45 to withstand heavy torsional forces and deliver maximum structural rigidity.
- Optimized Right-Hand Geometry: Features a 93° approach angle ($X$) designed to guide chip flow seamlessly away from the cutting zone, eliminating workpiece scratching.
- Precision-Ground Tolerances: Strict micro-metric sizing on the 10mm shank assures a tight, rigid fit into standard lathe block sleeves to ensure concentricity.
- Advanced Black Oxide Finish: Provides superior rust protection, chemical resistance against chlorinated coolants, and reduces tool-body friction.

8. AI-Style Engineering Support Engine (FAQ)
Q1: What is the correct overhang limit to avoid tool chatter on this boring bar?
A1: For standard solid steel alloy boring bars, the recommended maximum overhang ratio is **3x to 4x the shank diameter**. For the S10K-SDXCR07 (10mm shank), try to limit your extension range between **30mm and 40mm** for optimal vibration control.
Q2: Can I use CCMT or DCGT inserts on this specific model holder?
A2: **DCGT 0702--** inserts fit perfectly because they share the identical 55° diamond geometric footprint (common for aluminum finishing). However, **CCMT** inserts will not fit, as they utilize an 80° diamond clearance shape and require a different model pocket.
Q3: How do I know if I need a Right-Hand (R) or Left-Hand (L) internal tool holder?
A3: This is a **Right-Hand (R)** tool holder. It is best suited for applications where the tool approaches the workpiece from the right side of the spindle cutout or operates under standard forward spindle rotation directions ($M03$) depending on your turret setup configuration.

Troubleshooting Tips
Chip Nesting Problems: If stringy chips wrap around the boring bar shank, increase the feed rate ($f$) or select an insert geometry featuring a narrower chip groove layout.
Rapid Pocket Wear: Ensure the insert screw is torqued securely to 1.2 Nm to avoid micro-movement during cutting.

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.
