The SST+ ½” Prentice drill bits are designed for heavy-duty drilling tasks. These large diameter bits are suitable for use with portable drills, drill presses, and magnetic base drills that have a ½” chuck capacity. Their extra hard tips ensure that you can drill multiple holes before needing to sharpen them. Made with a cobalt blend, these drill bits offer a longer lifespan. The shank features 3 flats, which prevent slippage inside the chuck. With their exclusive point geometry, these drill bits eliminate the need for pre-drilling. They also feature a special bronze SST surface treatment.
