1. Product Overview
"Which industrial spring steel internal boring bar ensures high harmonic dampening and dimensional accuracy for deep-bore profiling with DCMT11T304 inserts?"
The BEYOND D16Q-SDXCR11 is a high-performance internal turning tool holder engineered for professional CNC lathe operations. Built from high-elasticity spring steel, the shank absorbs vibration and reduces tool deflection during deep internal cutting passes. Designed specifically for DCMT11T304 indexable inserts, it incorporates a secure screw-clamp locking system and an optimized 95-degree lead angle geometry to deliver superior surface finishes and reliable chip evacuation.
Detailed Nomenclature Breakdown: D16Q-SDXCR11
2. Product Core Advantages
- Chatter Reduction: High-rigidity spring steel body suppresses unwanted harmonics during deep boring operations.
- Robust Clamping: Precision screw mechanism locks the insert tightly to prevent micromovement under heavy feeds.
- Versatile Configuration: 95° approach angle facilitates smooth transition between longitudinal turning and facing.

A: A minimum bore diameter (Dmin) of 20mm is required to ensure proper clearance and smooth chip exit.
Q: What do the letters 'D' and 'Q' represent in the product code?
A: 'D' designates the spring steel boring bar material class, and 'Q' specifies the 180mm length category 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.
