CCMT09T304-LP MC6015
High-Speed Finishing Master | Nano-Texture CVD | LP Precision Geometry
MC6015 Grade & LP Geometry
MC6015 Grade (The High-Speed CVD): Engineered for high-speed continuous turning of steel. This grade features a specialized Nano-Texture Technology CVD coating that enhances crystal grain alignment. The result? Unmatched resistance to crater wear and heat, allowing you to push surface speeds (Vc) to their limit without sacrificing tool life.
LP Chipbreaker (Light-cut Precision): The LP geometry is Mitsubishi's premier choice for Finishing. It is designed to control chips at very shallow depths of cut. The sharp cutting edge and specialized rake angle reduce cutting forces, which prevents vibration and ensures a superior surface finish on slender or long workpieces.
0.4mm Precision Radius: The 04 (1/64") radius provides high-resolution surface finishes. It is the "gold standard" for finishing passes where dimensional accuracy is the top priority.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CCMT09T304-LP | 9.525 mm | 3.97 mm | 0.40 mm |
| Imperial | CCMT32.51-LP | 3/8" | 5/32" | 0.0157" (1/64") |
Recommended Finishing Parameters
*Optimized for high-speed continuous turning. For best surface finish, use within the recommended feed range of the LP breaker.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Mild Steel (S10C/1010) | 250 - 450 m/min | 0.05 - 0.20 mm/r | 0.20 - 1.20 mm |
| Carbon/Alloy Steel (1045/4140) | 200 - 380 m/min | 0.05 - 0.15 mm/r | 0.20 - 1.00 mm |

Shop SCLCR 09 HoldersPro-Tip: MC6015 vs. MC6025
MC6015 (CVD): Optimized for High-Speed (P15) continuous cuts. It has the highest wear resistance but is less shock-resistant.
MC6025 (CVD): The general-purpose (P25) choice. Switch to MC6025 if you have light interrupted cuts or unstable machining conditions where edge chipping is a concern.

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.
