| Corner Radius (RE) | 2.0 mm (.0787") |
| Grade / Coating | VP15TF (Miracle PVD Coating) |
VP15TF Miracle Coating
The VP15TF grade is the industry standard for versatility. It utilizes a micro-grain carbide substrate and a Miracle PVD coating that provides high resistance to built-up edge (BUE) and thermal cracking. This makes it ideal for indexable milling stainless steel and tough alloys where chip adhesion is common.
JM High-Feed Geometry
The JM (General Machining) chipbreaker is optimized for high feed metal removal. It features a reinforced cutting edge that distributes force across the insert, allowing for aggressive table feeds while protecting against edge chipping during interrupted cuts or unstable setups.
