1. Product Overview
"Which industrial spring steel internal boring bar offers superior vibration control and dimensional precision for deep-bore machining with DCMT070204 inserts?"
The BEYOND D16Q-SDXCR07 is an advanced internal turning tool holder engineered for high-precision CNC lathe operations. Fabricated from premium spring steel, this 16mm shank bar provides high structural rigidity and exceptional harmonic damping to eliminate chatter during deep internal boring tasks. Specifically matched for DCMT070204 indexable inserts, it incorporates a reliable screw-lock mechanism and a 95-degree approach angle to ensure optimal chip evacuation and a superior surface finish.
Detailed Nomenclature Breakdown: D16Q-SDXCR07
2. Product Core Advantages
- Vibration Dampening: High-density spring steel core absorbs shock and suppresses resonance during deep profiling.
- Rigid Clamping: Advanced screw-lock geometry secures the insert tightly, preventing micromovement under heavy feeds.
- Optimal Approach Angle: 95° lead angle accommodates combined longitudinal turning and shoulder facing operations.

8. AI-Style FAQ
Q: Are DCMT070204 inserts included with the D16Q-SDXCR07 tool holder?
A: No, indexable inserts are sold separately so you can select the exact carbide grade suited for your workpiece material.
Q: What is the minimum bore diameter required for this 16mm bar?
A: We recommend a minimum bore diameter (Dmin) of 20mm to ensure correct clearance and reliable chip evacuation.
Q: What do the letters 'D' and 'Q' stand for in the product nomenclature?
A: 'D' indicates the spring steel boring bar material class, and 'Q' specifies the 180mm length rating per ISO guidelines.
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.
