01J012 - Walter SST Cobalt Stub Drill Bit #12 - Heavy Duty Sheet Metal Bit

High-Performance Drilling with Walter SST Stub Drill Bits

The Walter 01J012 #12 SST Stub Drill is a premium cutting tool engineered for the most demanding drilling applications. Designed with the industrial professional in mind, this drill bit addresses the common challenges faced when working with thin gauge materials and hard alloys. Unlike standard jobber-length bits that can flex and wander, the SST Stub Drill features a compact overall length and shortened flutes. This structural design significantly increases the rigidity of the bit, ensuring precise hole placement and virtually eliminating the risk of snapping under pressure.

Manufactured from a high-grade cobalt blend, this bit is built to withstand the high temperatures generated when drilling through tough materials like stainless steel and mild steel. The addition of cobalt extends the cutting life of the tool far beyond that of standard high-speed steel bits. Furthermore, Walter has applied a specialized bronze SST surface treatment. This coating acts as a lubricant and heat deflector, allowing for faster drilling speeds while maintaining the integrity of the cutting edge over prolonged use.

Efficiency is key in any production environment, and the Walter 01J012 delivers with its advanced split-point geometry. This feature allows the bit to self-center immediately upon contact with the workpiece, removing the need for pre-punching or pilot holes. Whether you are drilling into flat sheet metal, round tubing, or using a stationary drill press, this bit provides the stability and bite required for clean, burr-free holes. It is an essential tool for maintenance, repair, and operations (MRO) professionals seeking reliability and performance.
