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.
