MMT16ERAG60-S VP15TF
Mitsubishi Materials | External Partial Profile 60° AG (Metric / UN / UNC / UNF)
The Mitsubishi MMT16ERAG60-S VP15TF is a highly versatile external threading insert featuring a partial profile 60-degree AG geometry. The "AG" designation offers an expanded pitch range, allowing a single insert to machine threads from 0.5mm to 3.0mm (48 to 8 TPI). This versatility makes it a must-have for CNC threading shops handling varied Metric and Unified National (UN) requirements. Built with the -S type 3D molded chipbreaker and protected by VP15TF Miracle PVD coating, this insert dominates in threading stainless steel and tough alloys where chip control is paramount.

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 stainless steel.
-S Type 3D Chipbreaker
External threading on larger pitches can produce dangerous continuous chips. The -S molded chipbreaker utilizes 3D geometry to curl and break chips into small spirals. This reduces cutting resistance and heat, ensuring 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.
