Originally built from M42 cobalt steel for extreme wear resistance, our Predator™ Step Drill Bits (also known as unibits, cone bits, or multi-step drill bits) deliver clean, precise holes through stainless, sheet metal, and aluminum without chatter or burn-out.
The split-point tip starts fast with no wandering, and dual-flute geometry clears chips for cooler cutting and longer life. Trusted by fabricators, electricians, and HVAC pros who need reliability, accuracy, and long-term value.
