01J022 - Walter SST+ Cobalt Stub Drill Bit, Wire Gauge #22, Heavy Duty

High-Performance Drilling for Industrial Applications

The Walter SST+ Stub Drill Bit (Size #22) represents the pinnacle of drilling technology for industrial environments where precision, durability, and speed are paramount. Engineered specifically for the demands of modern fabrication, this drill bit features a robust cobalt blend construction. This material choice is critical for maintaining hardness at high temperatures, making it the superior choice for drilling through tough alloys like stainless steel and mild steel without premature dulling.

One of the defining characteristics of this tool is its "stub" or screw machine length. Unlike jobber length bits, the shorter overall profile and flute length of the SST Stub Drill provide unmatched rigidity. In industrial settings, bit breakage is a costly interruption; the stout design of the 01J022 minimizes flexion and torque-related snapping, ensuring consistent uptime. This rigidity also translates to greater accuracy, as the bit is less prone to wandering or deflecting when it first contacts the workpiece.

Surface technology plays a vital role in the performance of Walter tools. This bit is finished with a unique Bronze SST surface treatment. This specialized coating serves a dual purpose: it significantly reduces friction between the tool and the material, and it aids in the smooth evacuation of chips. The result is a cooler drilling process and a cleaner hole. Furthermore, the precision-ground split point geometry allows for instant penetration. Operators can forego the time-consuming step of center punching, as the bit self-centers immediately upon contact, even on curved surfaces or round stock.

Whether utilized in stationary machining centers or portable hand drills, the Walter #22 SST Stub Drill delivers reliable performance. It is particularly effective for sheet metal work where the short length allows for better control and the split point prevents the bit from "walking" across the surface. Invest in tools that match the quality of your work with Walter's industry-leading drilling solutions.
