DCMT11T308-HR YBC151 Steel Machining Inserts
Product Overview
The DCMT11T308-HR YBC151 is a high-performance 55° rhombic positive insert designed for Steel (P-Class) applications. Featuring the YBC151 Grade—a combination of a thick Al2O3 and TiN CVD coating—this insert is optimized for high-speed cutting in stable conditions. The -HR (Heavy Roughing) chipbreaker provides a robust cutting edge with a large rake angle, ensuring effective chip control even at high depths of cut and heavy feed rates.
Core Advantages
- ✅ YBC151 Grade: Superior wear resistance for P05–P20 steel machining at elevated surface speeds.
- ✅ HR Chipbreaker: Engineered for roughing, offering excellent edge strength and reliable chip breaking in long-chip materials.
- ✅ Thick CVD Coating: Provides a thermal barrier that prevents crater wear during dry or high-speed wet machining.
- ✅ 0.8mm Radius: Optimized for durability and higher metal removal rates (MRR) compared to 0.4mm variants.

1. Can YBC151 be used for stainless steel?
While possible in a pinch, it is optimized for Steel (P). For Stainless, the YBM series is highly recommended.
2. What is the difference between -HR and -HM?
-HR is for heavy roughing with higher feed rates, while -HM is for medium-duty general machining.
3. Should I use coolant with YBC151?
Yes, for high-speed roughing, coolant helps evacuate chips and further extends the life of the CVD coating.
Pro Tip: YBC151 is your go-to for speed. If you experience edge chipping due to vibration, consider switching to YBC251 or YBC351 for increased toughness.
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.
