MMT16ER200ISO-S VP15TF
Mitsubishi Materials | MMT Series External ISO Metric 2.0mm Pitch
The Mitsubishi MMT16ER200ISO-S VP15TF is a precision-ground external threading insert specifically engineered for 2.0mm pitch ISO metric threads. As a heavy-duty variant in the MMT series, this insert features the advanced -S type 3D molded chipbreaker. This geometry is critical for managing the high metal removal rates associated with a 2.0 pitch, ensuring chips are curled and broken to prevent "bird-nesting" and surface damage. Coated with VP15TF Miracle PVD, it is the industrial benchmark for threading carbon steel, stainless steel, and alloyed materials.

VP15TF Miracle Grade
The VP15TF grade is Mitsubishi’s proprietary PVD grade, combining a micro-grain carbide substrate with the legendary Miracle (Al-Ti-N) coating. It provides exceptional wear resistance and anti-welding properties, making it the top choice for indexable threading in stainless steel (SUS304/316) where built-up edge (BUE) is a common failure mode.
-S Type 3D Chipbreaker
The -S molded chipbreaker is designed for modern CNC threading. Because 2.0mm pitch threads generate significant chip volume, the 3D rake surface actively curls the chip away from the thread flank. This results in lower cutting forces, reduced vibration, and a significantly improved surface finish compared to flat-top inserts.
