MMT16IR200ISO-S VP15TF
Mitsubishi Materials | Internal ISO Metric Threading | 2.0mm Pitch
The Mitsubishi MMT16IR200ISO-S VP15TF is a robust internal threading insert designed for 2.0mm pitch ISO metric threads (common for M14, M16 standard threads). As a part of the premium MMT series, this insert features the advanced -S type 3D chipbreaker, specifically designed for internal CNC threading where space is confined and chip evacuation is a challenge. Coated with the high-performance VP15TF Miracle PVD coating, it is the premier choice for threading carbon steel, stainless steel, and alloyed materials.

VP15TF Miracle Grade
The VP15TF grade is Mitsubishi's premier universal PVD grade. By pairing a high-toughness micro-grain substrate with the Miracle (Al-Ti-N) coating, it provides exceptional wear resistance and anti-welding properties. It is specifically designed to prevent built-up edge (BUE) when internal threading stainless steel (SUS304/316).
-S Type 3D Chipbreaker
In internal operations, chip control is paramount. The -S molded chipbreaker utilizes a 3D rake surface that actively curls and breaks the chip into smaller, manageable pieces. This ensures that chips are easily evacuated by the boring bar's coolant, preventing chip "nesting" which often results in surface damage or insert failure.

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.
