Walter 1 1/2 SST Prentice Drill (01M620)

Description

Walter 01M620 1 1/2 SST Prentice Drill Bit is engineered for heavy-duty, large-diameter drilling applications. Designed for use in portable drills, drill presses, and magnetic base drills with a 1/2″ chuck capacity, this drill bit delivers precision, durability, and efficiency. Its cobalt blend construction allows for extended tool life and faster drilling through tough materials such as hardened steels and stainless steel. The extra-hard cutting tip ensures more holes between re-sharpenings, while its advanced design minimizes walking and reduces thrust.

Features:

• 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.
• Extra-hard tip for longer service life and consistent drilling performance.

Benefits:

• Heavy-duty construction for precision and reliability in demanding applications.
• Extended tool life thanks to cobalt alloy and SST bronze surface finish.
• Faster drilling with minimized effort and walking.
• Secure grip in drill chucks with reduced slippage.
