Features

1. Precision Angles for Centering: Available in 90° and 120° point angles to perfectly match various drill entry requirements.
2. Premium ZrN-A Coating for High Lubricity & Anti-Adhesion: Engineered with a specialized ZrN-A (Zirconium Nitride) coating that offers an ultra-low friction coefficient and superior chip evacuation.

Application

• Excel at working carbon steels (~HB225), alloy steels (HB225~325), pre-hardened steels (up to HRC45), hardened Steels (HRC40~45), aluminum alloys and copper alloy.

Features

1. Designed for general chamfering and NC spot drilling applications.
2. The four-corner design offers four usable cutting edges for maximum cost efficiency.
3. The newly developed SH + ZrN coating, combined with an optimized spotting geometry, ensures stable centering, reduces friction, improves lubrication, and significantly extends tool life.

Application

• Ideal for machining carbon steels (up to HB225), alloy steels (HB225–325), cast iron, non-ferrous alloy, and similar materials.
