VP15TF "Miracle Coated" PVD Grade and JS Chipbreaker

The VP15TF grade utilizes Mitsubishi’s "Miracle Coating" (TiAlN PVD) applied over a high-toughness, micro-grain substrate. It is notable for its resistance to edge chipping and abrasive wear, even under conditions of interrupted cutting or inconsistent coolant application. The JS chipbreaker features an optimized geometric channel that effectively breaks chips during roughing and semi-finishing passes in deep cavities, preventing chips from being re-cut within the die or mold.

Technical Advantages

• High Cutting-Edge Toughness (12 mm diameter): Maximum mechanical strength at the corner; Allows the insert to be indexed multiple times, making full use of its entire circular perimeter.

• Universal PVD Coating (VP15TF): Exceptional adhesion of the TiAlN layer, which prevents the buildup of Built-Up Edge (BUE) when machining stainless steels.

• 11° Positive Geometry: Reduces machine power consumption and minimizes vibrations during long-overhang boring or milling operations.

• JS Free-Cutting Chipbreaker: Provides excellent chip control across a wide range of feed rates and depths of cut (ap).
