SCMT09T308 VP15TF
Mitsubishi Materials | Miracle Coated Strength & Versatility
The Mitsubishi SCMT09T308 VP15TF is a premium indexable turning insert designed for high-performance CNC machining. Utilizing a 0.8mm nose radius, this variant offers enhanced edge strength and higher feed capabilities compared to the 0.4mm version. Coated with the legendary VP15TF Miracle PVD, it is the ultimate tool for machining stainless steel, carbon steels, and heat-resistant superalloys (HRSA), providing a perfect balance of wear resistance and toughness.

VP15TF Miracle Grade
The VP15TF Miracle grade is a flagship PVD coating technology. By combining a high-toughness micro-grain substrate with an Aluminum Titanium Nitride (AlTiN) coating, it provides incredible resistance to built-up edge and crater wear. It is particularly effective for interrupted cuts where other inserts might chip.
Strong Edge Geometry
The 0.8mm radius (08) provides a stronger cutting edge than thinner variants, significantly reducing cutting resistance for larger depths of cut. This precision machining geometry ensures stable surface finishes even under high-load semi-finishing conditions in stainless steel production.
Recommended Cutting Parameters
Optimized for VP15TF Performance
| Workpiece Material | Cutting Speed ($v_c$) | Feed Rate ($f$) | Depth of Cut ($a_p$) |
|---|---|---|---|
| Stainless Steel (SUS304/316) | 100 - 160 m/min | 0.10 - 0.30 mm/rev | 0.5 - 2.5 mm |
| Alloy Steel (4140) | 120 - 200 m/min | 0.12 - 0.35 mm/rev | 1.0 - 3.0 mm |

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.
