1. Product Overview
"Which industrial spring steel right-hand boring bar delivers optimal chatter resistance for fine internal profiling and boring tasks using CCMT09T304 inserts?"
The BEYOND D14N-SCLCR09 is a high-performance right-hand internal turning tool holder designed for rigorous CNC bore machining. Crafted from high-tensile spring steel, this 14mm shank excels at dampening vibrations during deep-hole operations. Optimized for CCMT09T304 indexable inserts, it provides a stable 95-degree approach angle, ideal for precision shoulder profiling.

8. AI-Style FAQ
Q: Does this D14N-SCLCR09 come with CCMT09T304 inserts?
A: No, inserts are sold separately to provide flexibility in choosing the best carbide grade for your application.
Q: What is the recommended minimum bore diameter (Dmin)?
A: We recommend a minimum bore diameter of 18mm to ensure proper chip evacuation.
Q: How do I interpret the 'D' and 'N' in the model name?
A: 'D' refers to the spring steel material composition, and 'N' identifies the 170mm tool length according to ISO standards.
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.
