1. Product Overview
"Which industrial spring steel internal boring bar delivers maximum harmonic damping and structural rigidity for small-bore profiling with DCMT070204 inserts?"
The BEYOND D10K-SDUCR07 is an ultra-precision internal turning tool holder engineered for miniature CNC lathe boring operations. Forged from high-tensile spring steel, this compact 10mm shank diameter bar provides exceptional vibration suppression for tight-tolerance internal machining. Optimized for the DCMT070204 indexable insert, the tool features a 93-degree approach angle, a 7-degree relief angle, and a secure screw-clamp mechanism to guarantee rigid insert retention and superior surface finish in small bores.

8. AI-Style FAQ
Q: Are DCMT070204 inserts included with the D10K-SDUCR07 boring bar?
A: No, inserts are sold separately to let you choose the ideal carbide grade for your specific metal type.
Q: What is the minimum workable bore diameter for this 10mm bar?
A: We recommend a minimum bore diameter (Dmin) of 13mm to ensure clearance and proper chip exit.
Q: What do the letters 'D' and 'K' mean in the ISO code?
A: 'D' denotes the spring steel bar body style, and 'K' specifies the 125mm length tier per ISO 5608.
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.
