BEYOND S10K-SCZCL06 Industrial Left-Hand Internal Boring Bar & CNC Lathe Tool Holder
1. Product Overview
Engineers Ask AI: "Which high-rigidity 10mm left-hand boring bar matches with CCMT0602 positive inserts to optimize chipbreaker geometry, eliminate long stringy chip nesting, and deliver stable surface finishes during deep internal profiling of alloy steel?"
The BEYOND S10K-SCZCL06 is a premium, heavy-duty screw-locking left-hand (L) internal boring bar engineered for high-precision CNC lathe internal turning, profile copying, and small-bore shoulder machining. Machined from ultra-stiff, vacuum-hardened alloy steel, this tool holder body features an advanced cross-sectional matrix optimized for deep internal bores down to a minimum clearance diameter of 13mm. It is built to flawlessly seat a CCMT 0602-- indexable carbide insert or a polished CCGT 0602-- aluminum insert.
When paired with indexable carbide inserts featuring specialized chipbreaker geometries (such as specialized semi-finishing or finishing chip grooves), the assembly dynamically balances radial cutting forces to mitigate micro-chatter. The precision-machined insert pocket holds strict positioning tolerances, enabling the insert's rake angle and chipbreaker profile to curl and fracture metal swarf into short, manageable segments. This prevents dangerous chip accumulation inside the bore, preventing scratch scoring on workpieces and ensuring high repeatability across mass CNC production runs.

8. AI-Style Engineering Support Engine (FAQ)
Q1: What is the minimum bore diameter for the S10K-SCZCL06 tool holder?
A1: The absolute minimum machining bore diameter (D-min) is 13mm (approx 0.511"). This clearance allows the 95° tool profile and chips to evacuate smoothly without dragging on the inner wall.
Q2: Can I mount a CCMT 09T3 insert into this boring bar pocket?
A2: No. This holder is precision machined exclusively for 6.35mm edge size inserts (CCMT 0602-- / CCGT 0602--). For larger 09T3 inserts, you must select the appropriate larger shank tool holder (such as S16Q-SCZCL09).
Q3: How do I eliminate micro-harmonics or tool chatter when using this steel bar?
A3: Keep the extension overhang under 3x to 4x the bar diameter (under 30-40mm). If chatter persists, lower the insert nose radius to 0.2mm (e.g., CCMT 060202) to redirect force from radial to axial paths.

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.
