Designed for maximum versatility and performance, these premium cobalt jobber drill bits deliver the best of all worlds—exceptional results in handheld drills and drill presses alike. The jobber length offers the ideal balance of reach and rigidity, while solid cobalt steel construction (not coated) maintains cutting hardness under heat and load. A 135° split point bites immediately with minimal walking, reducing pressure and heat while improving hole accuracy and tool life. Finished with a 3-flat shank for secure chuck grip and built to ANSI standards, these fractional cobalt drill bits up to 1/2″ are engineered to power through stainless steel, hardened steel, cast iron, and other demanding materials—one high-performance drill bit that works everywhere without compromise.
