Mastering Titanium & Heat-Resistant Super Alloys
MP9005 Grade (The Thermal Barrier): The MP9005 is Mitsubishi's premium PVD-coated grade for S-Class materials. When machining Inconel, Waspaloy, or Titanium, heat stays at the cutting edge. MP9005 uses a specialized Al-Ti-Cr-N coating that provides extreme hardness at high temperatures, preventing plastic deformation of the tool tip while maintaining a razor-sharp edge.
LS Chipbreaker (Low-Stress Finishing): The LS geometry is specifically tuned for finishing operations in gummy, high-strength alloys. It features a sharp rake angle to slice through the material cleanly, which is critical to avoid work-hardening the workpiece—a common failure in aerospace component manufacturing.
0.2mm (0.0078") Ultra-Precision Radius: The 02 radius is designed for finishing passes where tight tolerances and low radial force are mandatory. It is the ideal choice for thin-walled aerospace parts where vibration (chatter) must be eliminated.

HRSA & Titanium Cutting Parameters
*High-pressure coolant is strongly recommended to evacuate heat and ensure surface integrity.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Titanium Alloys (Ti-6Al-4V) | 40 - 80 m/min | 0.05 - 0.15 mm/r | 0.10 - 1.00 mm |
| Inconel 718 / Waspaloy | 25 - 50 m/min | 0.05 - 0.12 mm/r | 0.10 - 0.80 mm |

Shop Precision HoldersPro-Tip: MP9005 vs. MP9015
MP9005 (The Hard Finisher): Best for continuous finishing and high-speed cycles in super alloys. Offers the highest wear resistance in the MP series.
MP9015 (The Stable All-Rounder): Switch to MP9015 for semi-finishing or if you encounter light interruptions/vibration during the cut.

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.
