MMT16ER150ISO-S VP15TF
Mitsubishi Materials | MMT Series External ISO Metric Threading
The Mitsubishi MMT16ER150ISO-S VP15TF is a precision-ground external threading insert designed for 1.5mm pitch ISO metric threads. As a flagship product in the MMT series, this insert is equipped with the advanced -S type 3D chipbreaker, engineered to provide superior chip control during heavy-duty threading cycles. Coated with the high-performance VP15TF Miracle PVD coating, it is the industry standard for threading steel, stainless steel, and alloyed materials where edge toughness is paramount.

| Grade / Coating | VP15TF (Miracle PVD Coated) |
VP15TF Miracle Grade
The VP15TF grade utilizes a high-toughness micro-grain carbide substrate combined with the specialized Miracle Al-Ti-N coating. This grade excels in indexable threading by providing high fracture resistance and preventing built-up edge (BUE), specifically when machining sticky materials like stainless steel or low-carbon steels.
-S Type 3D Chipbreaker
The -S type 3D geometry features a molded rake surface that actively curls chips into manageable shapes. In CNC threading, this geometry reduces cutting forces and prevents long ribbon chips from wrapping around the workpiece, ensuring a pristine thread surface and protecting the threading tool holder.

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.
