GC4425 Grade Technology
The GC4425 grade is Sandvik's latest generation steel turning solution. Featuring Inveio® technology, the uni-directional crystal orientation in the alumina coating layer provides extreme wear resistance and thermal protection, making it the top choice for long tool life in ISO P25 steel applications.
-MR Chipbreaker Geometry
The -MR (Medium Roughing) geometry is engineered for stability. It is a robust chipbreaker designed to handle heavy machining and varying depths of cut. It ensures reliable chip evacuation even in tougher, scaled surfaces of forged or cast steel components.
RECOMMENDED CUTTING DATA
Optimized for Steel (P) Machining
| Parameter | Metric Units | Imperial Units |
|---|---|---|
| Cutting Speed (vc) | 180 - 380 m/min | 590 - 1245 sfm |
| Feed Rate (fn) | 0.30 - 0.70 mm/rev | 0.012 - 0.028 in/rev |
| Depth of Cut (ap) | 1.5 - 8.0 mm | 0.059 - 0.315 in |
Grade Selection Pro-Tip:
- GC4425: Your first choice for reliability and long tool life in most steel turning operations.
- GC4415: Use for high-speed finishing and continuous cuts where heat generation is high.
- GC4335: The heavy-duty alternative for heavily interrupted cuts and extremely unstable setups.
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.
