VP15TF Miracle Coating
The VP15TF grade utilizes Mitsubishi's proprietary Miracle PVD coating. This specialized coating provides high adhesion and oxidation resistance, making it an excellent indexable turning insert for materials that tend to cause built-up edge (BUE), such as 304/316 stainless steel.
MA Chipbreaker Logic
The MA chipbreaker is a medium-cutting geometry that balances edge sharpness with structural strength. It excels in chip evacuation across a broad range of workpiece materials, reducing cutting heat and protecting the cutting edge during long production runs.
