SPKN1504EDSKR YBC301
ZCC.CT Professional Grade Carbide Milling Insert
Product Overview
The ZCC.CT SPKN1504EDSKR is a high-performance square milling insert designed for heavy-duty face milling and shoulder milling operations. Engineered with the YBC301 CVD coated grade, this insert provides exceptional thermal stability and wear resistance, making it the premier choice for steel machining solutions in high-speed CNC environments.
| Specification | Details |
| ISO Metric Model | SPKN1504EDSKR |
| ANSI/Inch Equivalent | SPKN 43 EDSKR |
| Grade | YBC301 (CVD Al2O3 + TiCN Coated) |
| Insert Shape | Square (S) with 15° Clearance Angle |
YBC301 Grade Technology
YBC301 is a "Black Diamond" series grade featuring a thick CVD Al2O3 coating combined with a gradient carbide substrate. This specific material is optimized for medium-to-roughing steel milling, offering a perfect balance between toughness and deformation resistance.
SKR Geometry Design
The SKR geometry (chipbreaker) is specifically designed for high-stability cutting. The reinforced cutting edge provides excellent chip control during heavy-duty applications, reducing vibrations and extending the tool life of your indexable milling cutters.
Recommended Cutting Parameters
| Workpiece Material | Cutting Speed (Vc) | Feed per Tooth (fz) |
|---|---|---|
| Carbon Steel (P10-P25) | 180 - 280 m/min | 0.15 - 0.40 mm/t |
| Alloy Steel (P25-P35) | 150 - 220 m/min | 0.12 - 0.35 mm/t |
*Note: For imperial conversions: Vc (sfm) = Vc (m/min) × 3.28; fz (inch/t) = fz (mm/t) ÷ 25.4.
Compatible Tooling:
This insert is designed for use with ZCC.CT FMA01 and SMP01 series face mills.

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.
