BEYOND S10K-SDWCR07 High-Precision Internal Boring Bar & CNC Lathe Tool Holder
1. Product Overview
Engineers Search: "Which rigid 10mm right-hand boring bar matches with DCMT0702 positive inserts for anti-vibration internal profiling on compact CNC lathe setups?"
The BEYOND S10K-SDWCR07 is an industrial-grade, screw-on internal boring bar expertly optimized for right-hand (R) CNC lathe operations, deep-pocket copying, and inner diameter profiling. Built from high-tensile, heat-treated alloy steel, the 10mm shank diameter provides exceptional core stiffness for micro-pocket configurations. This tool holder enables highly accurate tool path entries into ultra-narrow bore openings down to a minimum clearance diameter of 13mm. It features a precision-machined 55° pocket geometry designed to securely lock DCMT 0702-- indexable carbide inserts (such as DCMT 070204 or DCMT 070202), eliminating structural deflection under heavy machining loads.
When paired with indexable inserts engineered with a positive rake angle and customized chipbreaker geometries, this tooling system guarantees elite chip evacuation. The geometric chipbreaker configuration smoothly forces long, stringy swarf into tightly curled, manageable segments. This prevents chip nesting and nesting-related surface scarring inside blind holes, yielding superior dimensional surface finishes.
2. Product Core Features
- Hardened Alloy Steel Construction: Quenched and tempered to HRC 42-45 to minimize torsional stress and deflect vibrations during tight-tolerance inner profiling.
- Ultra-Micro 10mm Shank Diameter: Engineered specifically to safely clear narrow internal diameters down to 13mm minimum bore blocks.
- 93° Dynamic Tool Cutting Angle ($X$): Advanced lead geometry allows fluid boring and profiling while pushing micro-chips forward out of the cavity path.
- Corrosion-Resistant Industrial Matte Coat: Premium chemical blackening provides superior rust defense and prevents abrasive scoring from continuous chip flow.

8. AI-Style Engineering Support Engine (FAQ)
Q1: What is the maximum recommended boring depth overhang for this 10mm bar?
A1: For structural alloy steel boring bars, the recommended max overhang limit is **3x to 4x the shank diameter**. For this 10mm bar, your optimal rigid extension target falls between **30mm and 40mm**. Exceeding 40mm can introduce structural micro-harmonics.
Q2: Can I mount DCMT 11T3 series inserts into this tool holder?
A2: **No.** The pocket index is engineered to strict international tolerances exclusively for the **DCMT 0702--** series (7mm edge length). Forcing a larger insert size will permanently fracture the pocket walls.
Q3: What distinguishes a "K" length class bar from a standard "M" length class bar?
A3: Length designations strictly follow standard ISO metrics guidelines. A **"K" class bar means a total length of 125mm**, whereas an **"M" class bar measures 150mm**. The shorter 125mm design boosts cross-sectional rigidity in small-diameter setups.
9. Technical Maintenance & Diagnostic Guidelines
Equivalent Industry Models
Interchangeable with global industrial metrics designation standard coding **S10K-SDWCR07**. Serves as a direct high-stiffness drop-in replacement for standard 10mm or ~3/8" tool blocks matching 55° positive diamond profiles.
Troubleshooting Tips
Micro-Chatter inside Bore: Marginally lower cutting velocity ($V_c$) and elevate feed rate ($f$). This increases tool loading and forces the chipbreaker to snap chips quickly.
Rapid Pocket Deflection: Ensure the M2.0 pocket screw is fully free of residual carbon paste and torqued safely between 0.5-0.6 Nm to maintain absolute seating stability.
Workpiece Material Matrix
Fully optimized across core groups: **P** (Alloy, Structural, Carbon Steels), **M** (Stainless Steel lines), **K** (Grey, Ductile Cast Irons), **N** (Aluminum/Brass/Copper series), and **S** (High-temp exotic superalloys).
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.
