Walter SST+ 5/32" Cobalt Blend Jobber Drill Bit

Cut Through Stainless Steel Like Butter

Every welder knows the frustration of a dull drill bit, especially when working with stainless steel. The Walter 5/32" SST+ Drill Bit (01A510) is the solution for fabricators who are tired of burning through cheap bits. Designed with the welder's needs in mind, this heavy-duty bit utilizes a special cobalt blend that resists the intense heat generated during drilling. This means the cutting edge stays sharp longer, allowing you to drill more holes per bit and spend less time swapping out worn tools. It is the ultimate companion for custom fabrication shops, automotive repair, and heavy industrial welding projects.

One of the standout features for metalworkers is the 135° split point. Standard bits often wander when you try to start a hole, scratching your polished stainless or aluminum surface. The SST+ bites instantly on contact, self-centering without the need for a pilot hole or a center punch. This is a massive time-saver when you are drilling out spot welds, prepping rivet holes, or mounting hardware on a finished assembly. The bit's stability allows for precise placement every time, ensuring your fabrication work looks professional and clean.

Speed matters in a busy shop. The Walter SST+ features a high-flow flute design that pulls chips out of the hole quickly. This prevents the chips from packing in and overheating the bit, which is the number one cause of premature failure in stainless steel drilling. The bronze surface treatment further aids in smooth cutting by reducing friction. Whether you are drilling through mild steel plate, aluminum extrusion, or 304 stainless, this bit delivers aggressive cutting performance with minimal effort. Add the Walter 01A510 to your toolbox and experience the difference that a premium, industrial-grade drill bit makes in your daily workflow.

Built for the Grind

Durability is key in welding environments. The fully ground body of the SST+ provides exceptional strength, resisting snapping even when you have to apply extra pressure. It fits securely in standard 3-jaw chucks and is tough enough to handle the vibration and torque of powerful hand drills. Stop struggling with inferior bits and upgrade to the Walter SST+ for reliable, clean, and fast drilling in any metal.
