The SST+ ½” Prentice drill bits are designed for heavy-duty drilling tasks. These large diameter drill bits can be used with portable drills, drill presses, and magnetic base drills that have a ½” chuck capacity. The extra hard tips of these drill bits allow for drilling numerous holes before needing to be sharpened. Made with a cobalt blend, they offer a longer lifespan. The shank features 3 flats to prevent slippage inside the chuck. With their exclusive point geometry, these drill bits eliminate the need for pre-drilling. Additionally, they come with a special bronze SST surface treatment for enhanced durability.
