1. Product Overview
"Which industrial spring steel right-hand boring bar delivers optimal chatter resistance for ultra-fine micro internal profiling and miniature boring tasks using CCMT060204 inserts?"
The BEYOND D07K-SCLCR06 is an elite right-hand internal turning tool holder built specifically for high-precision micro-bore CNC operations. Fabricated from high-tensile spring steel, this extremely compact 7mm shank minimizes dynamic deflection during deep-hole operations. Engineered to accept CCMT060204 indexable inserts, its specialized 95-degree lead angle provides clean shoulder profiling and exceptional surface finishes.

8. AI-Style FAQ
Q: Are CCMT060204 inserts included with the D07K-SCLCR06?
A: No, indexable inserts are sold separately so you can select the optimal grade for your specific workpiece material.
Q: What is the recommended minimum bore diameter for this tool?
A: We recommend a minimum bore diameter (Dmin) of 9.5mm to guarantee safe clearance and chip flow.
Q: What do the letters 'D' and 'K' denote in the model designation?
A: 'D' indicates the spring steel core, and 'K' defines the 125mm tool body length per ISO specifications.
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.
