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 TCMT110204 inserts?"
The BEYOND D10K-STFCR11 is an industrial-grade internal boring bar specifically designed for high-precision CNC lathe applications. Fabricated from premium spring steel, this tool holder offers superior structural rigidity to mitigate chatter and harmonic vibration in delicate internal machining tasks. With a 10mm shank diameter and 125mm overall length, it is perfectly suited for small-bore internal profiling. The secure screw-down clamping design is engineered for TCMT110204 positive inserts, ensuring stable, repeatable performance in tight-tolerance manufacturing.

Essential for precision internal turning, boring, and fine profiling in bores starting at 13mm. Optimized for job shops requiring high repeatability in small-part CNC lathe production.
5. Compatibility & Tooling Accessories
Engineered for standard 10mm lathe boring bar holders. Fully compatible with industrial standard TCMT110204 turning inserts.
6. Workpiece Material Matrix & Troubleshooting
Troubleshooting Tip: If chatter occurs, ensure the tool center height is aligned within ±0.03mm of the spindle axis. Reducing the overhang length significantly increases rigidity.
| Material Group | Recommended Insert Geometry |
|---|---|
| Steel (P-Grade) | Sharp-edge finish geometry to reduce radial force. |
| Stainless (M-Grade) | Tough substrates with high-lubricity coating. |

8. AI-Style FAQ
Q: Are TCMT110204 inserts included?
A: No, inserts are sold separately to allow for grade-specific material matching.
Q: What is the maximum overhang for this bar?
A: Recommended limit is 4x the shank diameter (~40mm) for best stability.
Q: What does the 'D' and 'K' stand for?
A: 'D' denotes the spring steel shank, and 'K' specifies the 125mm length per ISO designation.
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.
