The SST+ ½” Prentice drill bits are designed for heavy-duty drilling in portable drills, drill presses, and magnetic base drills with a ½” chuck capacity. These drill bits feature extra hard tips that allow for drilling a larger number of holes before needing to be sharpened. Made with a cobalt blend, they offer extended durability. Additionally, the 3 flats on the shank prevent slippage inside the chuck, ensuring stability during use. With their exclusive point geometry, pre-drilling is eliminated, resulting in more efficient drilling. Lastly, these drill bits are treated with a special bronze SST surface treatment.
