Walter 57/64 SST Prentice Drill (01M557)
Walter 01M557 57/64 SST Prentice Drill Bit is a heavy-duty large-diameter drill bit engineered for maximum durability and precision in demanding applications. Designed for use with portable drills, drill presses, and magnetic base drills equipped with a 1/2" chuck capacity, this bit delivers consistent performance on tough materials such as hardened steel and stainless steel. Its cobalt blend construction ensures a longer tool life, while the extra-hard cutting tip allows for more holes to be drilled between re-sharpenings. With advanced design features, it provides faster, smoother, and more reliable drilling results.
Made with premium grade cobalt HSS for drilling harder materials.
Cobalt drills approximately 30% faster than standard HSS bits.
Self-centering 135° split-point reduces thrust and prevents walking.
Special bronze SST surface treatment for extreme lubricity and extended life.
1/2" reduced shank for compatibility with standard drill chucks.
3-flats shank design reduces slippage in drill chucks.
Reliable drilling in portable drills, drill presses, and magnetic base drills.
Extended tool life with cobalt alloy and bronze SST surface finish.
Faster drilling with reduced effort and minimized bit walking.
Secure grip in drill chucks with 3-flats shank design.
