01A012 - Walter SST 3/16-Inch Cobalt Jobber Drill Bit with Quick Shank

High-Performance Drilling Solution for Industrial Applications

The Walter 01A012 3/16" SST Jobber Drill Bit represents a pinnacle in drilling technology, specifically engineered for the rigorous demands of industrial metalworking and maintenance operations. Designed with a proprietary cobalt blend, this tool offers exceptional hardness and heat resistance, significantly outperforming standard high-speed steel (HSS) bits in durability and longevity. This makes it an ideal choice for procurement managers seeking to reduce consumable costs and downtime associated with frequent bit changes.

One of the standout features of this drill bit is the innovative Quick Shank design. In high-volume production environments where time is money, the Quick Shank ensures a positive lock within the drill chuck, completely eliminating the issue of the bit spinning under load. This feature is compatible with both keyed and keyless chucks, providing versatility across various drilling equipment. Furthermore, the bit is optimized for energy efficiency, making it the perfect companion for cordless power tools by maximizing the number of holes drilled per battery charge.

The geometry of the Walter SST bit is crafted for precision. It features a heavy-duty, fully ground body with a back-tapered design that reduces friction and heat buildup—critical factors when drilling deep holes or working with tough alloys. The exclusive self-centering Speed Tip allows operators to start holes with pinpoint accuracy without the need for pre-punching, even on curved surfaces like pipes or tubing. Finished with a special bronze SST surface treatment, this drill bit ensures smooth chip evacuation and enhanced wear resistance, making it a reliable staple for any professional tool crib.
