01A005A - Walter SST+ 5/64" Cobalt Jobber Drill Bit with Quick Shank

Industrial Grade Precision for Metal Fabrication

For welders and fabricators who demand reliability and speed, the Walter 01A005A 5/64" SST+ Jobber Drill Bit is an essential addition to your tool arsenal. Drilling is often a preparatory step in welding and assembly, and having a bit that performs consistently can save hours of labor over the course of a project. This drill bit is crafted from a high-quality cobalt blend, specifically formulated to tackle a wide range of materials including aluminum, mild steel, and various non-ferrous metals. The inclusion of cobalt in the steel matrix provides superior red hardness, meaning the bit retains its cutting ability even at the elevated temperatures generated during continuous drilling operations.

The 01A005A is not just about material hardness; it is about intelligent design. The "Quick Shank" feature is a game-changer for professionals using handheld drills. By flattening specific areas of the shank, Walter has created a bit that refuses to spin inside the chuck. This secure grip ensures that every ounce of power from your drill is directed into the cut, providing a smooth and aggressive drilling action. This is particularly critical when working with thin gauge metals or sheet metal, where control is necessary to prevent hole distortion. The heavy-duty, fully ground body of the bit ensures straightness and concentricity, resulting in rounder, more precise holes that facilitate better fit-up for rivets, bolts, or welding fixtures.

Furthermore, the geometry of the SST+ bit is optimized for ease of use. The self-centering Speed Tip bites into the material instantly, allowing you to start holes exactly where you need them without the bit skating across the workpiece. This feature is invaluable when working in awkward positions or on curved surfaces where applying heavy feed pressure is difficult. The body of the bit is back-tapered, a subtle design choice that prevents the sides of the bit from rubbing against the hole walls. Combined with the exclusive bronze SST surface treatment, this design significantly reduces friction and heat, which are the primary enemies of drill bit longevity. With the Walter SST+ 5/64" bit, you get a tool that cuts faster, lasts longer, and helps you maintain the high standards of your fabrication work.

Applications and Benefits:

• Versatile Drilling: Excellent performance on mild steel, aluminum, and thin gauge metals.
• Cordless Efficiency: Designed to extend the battery life of cordless drills through efficient cutting.
• Precision Starts: No walking on curved surfaces, ensuring accurate hole placement.
• Reduced Downtime: Durable construction means fewer bit changes and less time sharpening.
