01M557 - Walter SST+ 57/64 Inch Cobalt Prentice Drill Bit with 1/2 Inch Shank

Introducing the SST+ ½” Prentice, a heavy-duty large diameter drill bit designed for use in portable drills, drill presses, and magnetic base drills with ½” chuck capacity. With their extra hard tips, these drill bits allow for drilling numerous holes without the need for frequent re-sharpenings. Crafted from a durable cobalt blend, they offer a longer lifespan. The inclusion of 3 flats on the shank eliminates slippage inside the chuck, resulting in more efficient drilling. The exclusive point geometry of these drill bits eliminates the need for pre-drilling, saving you time and effort. Additionally, they feature a special bronze SST surface treatment for added durability.
