01A012A - Walter SST+ 3/16" Jobber Drill Bit with Quick Shank - Cobalt Blend

High-Performance Drilling with Walter SST+ Technology

The Walter 01A012A 3/16" SST Jobber Drill Bit represents the pinnacle of drilling technology for industrial applications. Engineered from a proprietary cobalt blend, this drill bit is designed to withstand high temperatures and abrasive materials, making it significantly more durable than standard high-speed steel bits. The core strength of the SST bit lies in its ability to maintain a sharp cutting edge even under the stress of drilling through tough alloys, ensuring consistent performance over a long service life. This makes it an essential tool for maintenance, repair, and operations (MRO) environments where reliability is paramount.

One of the standout features of this model is the exclusive Quick Shank design. Traditional round shanks often suffer from slippage within the chuck, particularly under high-torque loads. The Quick Shank incorporates engineered flats that lock securely into both keyed and keyless chucks, ensuring positive drive transmission. This feature not only protects the drill chuck from damage caused by spinning bits but also maximizes the torque transfer to the cutting edge, resulting in faster and more efficient drilling operations.

Precision is key in metalworking, and the Walter SST bit delivers with its self-centering Speed Tip. This advanced geometry allows the bit to start cutting immediately upon contact with the workpiece, eliminating the tendency to "walk" or wander across the surface. This is particularly beneficial when drilling on curved surfaces or round stock. Furthermore, the bit features a heavy-duty fully ground body and a back-tapered design, which work together to reduce friction and heat buildup. The special bronze SST surface treatment further enhances lubricity, facilitating smooth chip evacuation and preventing galling.

Designed with the modern workforce in mind, the Walter SST drill bit is optimized for use with cordless power tools. Its efficient cutting action requires less energy, thereby extending the battery life of cordless drills and allowing operators to drill more holes per charge. Whether working with mild steel, aluminum, or thin gauge sheet metal, the 01A012A delivers professional-grade results with every rotation.
