ZCC.CT TCMT110204-HM YBC151 Turning Insert
Premium CVD Coated Carbide for High-Speed Steel Machining
Product Overview
"Which carbide insert grade is best for achieving high surface finish on carbon steel and alloy steel at high cutting speeds?"
The ZCC.CT TCMT110204-HM YBC151 is a high-performance triangular turning insert optimized for ISO P (Steel) materials. The YBC151 grade features a thick Al2O3 CVD coating combined with a high-strength substrate, making it the industry standard for finishing to semi-finishing applications. Its -HM chipbreaker geometry is specifically designed to handle medium feed rates, ensuring excellent chip evacuation and reducing heat build-up on the workpiece.

Global Customer Feedback
"Exceptional Finishing"
I used these on 4140 steel. The surface finish is mirror-like. Very impressed with the YBC151 grade durability.
— Mark S., USA 🇺🇸"Ottima qualità"
Inserti molto affidabili per lavorazioni ad alta velocità. Rapporto qualità-prezzo imbattibile.
— Roberto F., Italy 🇮🇹"Reliable Performance"
Great chip control. The HM breaker works perfectly even at lower feeds.
— Kenji H., Japan 🇯🇵Professional CNC FAQ
Q: Can I use YBC151 for interrupted cutting?
A: YBC151 is a hard grade optimized for continuous high-speed finishing. For heavy interrupted cuts, we recommend using the tougher YBC351 grade.
Q: What is the difference between YBC151 and YBC251?
A: YBC151 has higher wear resistance for high speeds, whereas YBC251 offers a better balance of toughness and wear resistance for general steel turning.
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.
