MMT11IR100ISO-S VP15TF
Mitsubishi Materials | MMT Series Internal ISO Metric Threading
The Mitsubishi MMT11IR100ISO-S VP15TF is a premium internal threading insert designed for 1.0mm pitch ISO metric threads. Part of the renowned MMT series, this insert features the -S type 3D chipbreaker, specifically engineered to manage chip flow in deep internal bores. Coated with the high-performance VP15TF Miracle PVD coating, this tool provides an exceptional balance of wear resistance and toughness, making it the ideal solution for threading steel, stainless steel, and difficult-to-cut alloys.

| Grade / Coating | VP15TF (Miracle PVD Coated) |
VP15TF Miracle Grade
The VP15TF grade is a micro-grain carbide substrate paired with the "Miracle" (Al-Ti-N) PVD coating. This combination offers high fracture resistance during interrupted cuts and excellent adhesion resistance. It is widely regarded as a universal grade for indexable threading where stability and edge longevity are required.
-S Type 3D Chipbreaker
The -S (3D) chipbreaker is designed to solve the common problem of long, stringy chips in internal threading. By forcing chip deformation, it prevents chip entanglement around the workpiece and the boring bar, ensuring a safer process and preventing surface damage on finished threads.

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.
