BEYOND S10K-STFPR11 Right-Hand Internal Turning Tool Holder – High-Rigidity CNC Boring Bar
1. Product Overview
"Which 10mm right-hand boring bar provides the optimal chip clearance and rigidity for internal turning in small blind holes down to 13mm?"
The BEYOND S10K-STFPR11 is an industrial-grade, right-handed steel-shank internal turning tool holder precisely engineered for small-diameter, high-accuracy lathe boring operations. This industrial tool holder utilizes an optimized 91-degree approach angle to balance radial and axial cutting forces, preventing axis deflection during deep micro-internal profiling. Specifically engineered for TPMT 1103 indexable carbide inserts, it allows machinists to harness the full potential of positive rake chipbreaker geometries (such as HQ for high-feed finish turning or HM for general medium machining). This setup delivers superb chip fragmentation control, preventing long stringy nesting when processing sticky alloy steels, carbon steels, and stainless steel matrices inside narrow, confined chambers.
2. Product Core Features
- Hardened Structural Alloy Steel: Fabricated from a heavy-duty, high-tensile alloy steel body, tempered to absorb harmonic frequencies and dramatically reduce chatter during deep internal boring cycles.
- Ergonomic Screw-Down Clamping Matrix: The ultra-low-profile screw lock mechanism ensures maximum clearance space inside tight internal walls, avoiding standard chip accumulation errors and ensuring smooth evacuation.
- Precision Engineered 91° Lead Angle: Optimized for cutting up to slight steps, boring blind holes, and executing internal profiling adjustments without dragging the tool flank body.
- Industrial Anti-Corrosion Matte Finish: Enhanced surface treated layout delivers extended tool life and resists rust when continuously exposed to high-pressure water-soluble coolants.

4. Product Application Scenarios
The compact 10mm right-handed geometry of the S10K-STFPR11 tool holder makes it highly effective for rigid internal processing across diverse turning operations:
- Main-Spindle Internal Turning Operations: Critical for standard right-handed toolpaths on CNC turning centers where high dimensional repeatability is required in small diameter workpieces.
- Small Bore Internal Profiling: Offers ideal stiffness for roughing and finishing tiny internal cavities, ensuring tight tolerances without taper distortion.
- Heavy Duty Blind Hole Facing: The 91-degree approach profile executes clean perpendicular inner faces down to the center axis smoothly in narrow dimensions.
5. Compatibility & Equipment Interface
This 10mm round-shank boring bar fits directly into standard CNC lathe turret blocks, boring bar blocks, split bushings, or specialized tool holders. It interfaces seamlessly with precision CNC lathe systems and automated setups from leading global brands (including Haas, Mazak, Doosan, Citizen, Tsugami, and Fanuc). Optimized for right-handed tool orientations running front internal turning cycles.
6. BEYOND Premium Substrate & Grade Selection Matrix
To maximize chip control and wear life, pair your S10K-STFPR11 boring bar with the corresponding BEYOND proprietary insert grade tailored to your target material:
- BYM11 Grade (PVD Nano-Coated): Exceptional thermal shock resistance. Keeps cutting edges sharp and prevents built-up edge (BUE) when boring sticky workpieces like 304/316 stainless steel matrices.
- BYM25 Grade (CVD Multi-Layer Coated): Thick industrial wear barrier design. Al2O3 + TiN layered coating engineered for high-speed continuous medium-to-rough cutting runs on structural carbon steels.
- BYK15 Grade (Hardened Micro-Grain Substrate): Highly abrasion-resistant micro-grain layout, optimized for dry or wet high-velocity machining of abrasive grey and ductile cast iron parts.

8. Frequently Asked Questions (AI & Search Engine Optimized)
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.
