MMT16ERA60-S VP15TF
Mitsubishi Materials | External Partial Profile 60° (Metric/UN/UNC/UNF)
The Mitsubishi MMT16ERA60-S VP15TF is a highly versatile external threading insert featuring a partial profile 60-degree geometry. Designed for maximum flexibility in CNC threading, the "A60" type allows you to machine a wide variety of pitches (0.5mm to 1.5mm / 48 to 16 TPI) with a single tool. Whether you are producing Metric or Unified threads, the integrated -S type 3D chipbreaker ensures superior chip control. Coated with the legendary VP15TF Miracle PVD coating, this insert is the industry's first choice for threading stainless steel, carbon steels, and tough alloyed materials.

| Grade / Coating | VP15TF (Miracle Al-Ti-N PVD) |
VP15TF Miracle Grade
The VP15TF grade is Mitsubishi's premium universal carbide solution. It features a micro-grain substrate coated with proprietary Miracle (Al-Ti-N) PVD. This grade offers extreme edge toughness and heat resistance, making it perfect for indexable threading in materials prone to built-up edge (BUE) like SUS304 and SUS316.
-S Type (3D) Chipbreaker
The -S molded chipbreaker is specifically engineered for threading chip control. By curling the chip into a spiral before it can nest, it prevents surface damage and reduces cutting forces. This leads to a superior thread surface finish and significantly longer tool life in high-speed CNC environments.

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.
