Description
Walter 01M562 31/32 SST Prentice Drill Bit is a heavy-duty large-diameter drill bit designed for precision, strength, and durability. Built for use with portable drills, drill presses, and magnetic base drills with a 1/2″ chuck capacity, this bit delivers reliable performance on tough materials like hardened steel and stainless steel. The cobalt blend construction extends tool life, while its extra-hard cutting tip allows for drilling more holes between re-sharpenings. With advanced features to reduce walking, minimize thrust, and enhance chip evacuation, this drill bit ensures efficient and accurate results in demanding applications.
