The SST+ ½” Prentice drill bits are designed for heavy-duty drilling applications 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 multiple holes before requiring re-sharpening. Made with a cobalt blend, they provide a longer lifespan. With three flats on the shank, these drill bits prevent slippage inside the chuck. They offer faster drilling speed and eliminate the need for pre-drilling with their exclusive point geometry. Additionally, they are treated with a special bronze SST surface treatment.
