Product Features & Advantages

Core Material Science: The Cobalt Advantage

Unlike standard HSS drills (like M2), our bits are formulated with a significant cobalt infusion. This alloying element fundamentally increases the steel's hot hardness (red hardness), allowing the cutting edge to retain its temper and sharpness under intense frictional heat generated when drilling tough materials.

Engineered for Peak Performance
