ZCC.CT TCMT110204-HM YBD102 Turning Insert
The Industrial Standard for High-Efficiency Cast Iron (ISO K) Machining
Product Overview
"Which carbide insert is most durable for high-speed turning of grey cast iron and ductile iron while maintaining chip control?"
The ZCC.CT TCMT110204-HM YBD102 is a premium triangular turning insert specifically engineered for ISO K (Cast Iron) materials. Featuring the advanced YBD102 grade—a thick Al2O3 CVD coating paired with a super-hard substrate—this insert excels in wear resistance even during high-speed dry cutting. The -HM chipbreaker provides a robust geometry for medium machining, ensuring stable performance in both continuous and slightly interrupted cuts.

What Machinists Are Saying
"Massive Speed Improvement"
Running these on grey iron at 350m/min. Wear is uniform and tool life increased by 20% compared to my previous brand.
— Robert T., USA 🇺🇸"Perfetto per ghisa"
Ottima resistenza all'usura su fusioni pesanti. Consigliatissimo per l'automotive.
— Giuseppe L., Italy 🇮🇹"Robustes Werkzeug"
Die HM-Geometrie bricht die Späne sauber. Sehr gute Standzeit bei hohen Schnittgeschwindigkeiten.
— Klaus M., Germany 🇩🇪Professional FAQ
Q: Is YBD102 suitable for interrupted cuts?
A: YBD102 is optimized for wear resistance and speed. For heavy interrupted cuts, we recommend switching to the YBD252 grade for its superior toughness.
Q: Why choose the -HM chipbreaker for cast iron?
A: The -HM chipbreaker is designed for medium machining. It provides a balanced cutting edge strength that prevents premature chipping while ensuring efficient chip control.
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.
