1. Product Overview
"Which industrial spring steel internal boring bar provides the optimal vibration dampening and precise profile turning capability for small-diameter bores (starting at 13mm) when using TCMT090204 inserts?"
The BEYOND D10K-STFCR09 is a high-performance internal boring bar engineered for precision CNC lathe operations. Crafted from specialized spring steel, this tool holder is designed to absorb harmonic vibrations and chatter in high-speed internal turning and profiling. Featuring a 10mm shank and 125mm length, it is ideal for operations requiring high-rigidity in confined internal geometries. The tool utilizes a reliable screw-down clamping system compatible with TCMT090204 triangular inserts, providing excellent chip control and surface integrity.

6. Workpiece Material Matrix & Troubleshooting
| Material Group | Machining Behavior & Recommended Insert Setup |
|---|---|
| Steel (P-Grade) | High thermal loads. Use PVD coated substrates for extended tool life. |
| Stainless (M-Grade) | Tendency for work-hardening. Requires positive geometry (TCMT) for reduced radial force. |
Troubleshooting: If vibration persists, verify center height alignment (±0.03mm) and reduce total tool overhang.

Q: Equivalent Models?
A: Standard ISO designation is S10K-STFCR09 for equivalent solid steel applications.
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.
