OVERVIEW

Drill Stainless Steel Without the Headache

Every welder knows the frustration of burning through drill bit after drill bit when working with stainless steel. The Walter 11/32" SST+ Drill Bit (01A522) is the solution to that problem. Designed with the professional fabricator in mind, this bit is built to bite hard and last long. It is made with a special cobalt blend that stands up to the intense heat generated when drilling hard metals. While standard black oxide bits might smoke and dull after a few holes, the SST+ keeps its edge, allowing you to drill more holes per bit and spend less time swapping out tools.

One of the standout features for job site work is the 135-degree split point. If you are drilling into a pipe, a railing, or a flat plate without a pilot hole, this bit stays exactly where you put it. It won't wander or "walk" across the metal, which saves your workpiece from scratches and ensures your holes are exactly where they need to be. The "High Flow" flute design is another huge advantage; it pulls metal chips out of the hole quickly. This keeps the bit cooler and prevents it from binding up, which is a common way to snap bits when drilling by hand.

Whether you are installing brackets, fabricating custom parts, or doing general MRO work, the Walter SST+ is the reliable choice. It cuts through mild steel like butter and handles stainless steel with authority. For the best results and even longer life, we recommend pairing this bit with a high-quality cutting lubricant like Walter Coolcut. This bit isn't just a consumable; it's a productivity tool that helps you finish the job faster and with less effort.

Why Welders Choose SST+

  • No Walking: The split point tip grabs the metal instantly, even on round tubing.
  • Longer Life: Cobalt blend resists heat, the #1 killer of drill bits in stainless.
  • Faster Drilling: Aggressive cutting geometry means less pressure is needed from you.
  • Versatile: Works great on stainless, steel, and aluminum.

FAQ

The Walter SST+ drill bits are made from a premium cobalt blend High-Speed Steel (HSS), which provides superior heat resistance and hardness compared to standard HSS bits.

Yes, the SST+ series is specifically engineered for drilling stainless steel and other hard alloys effectively.

No, the 135° split point design allows the bit to self-center and start cutting immediately, eliminating the need for a center punch or pilot hole.

The bronze SST surface treatment reduces friction between the bit and the workpiece, allowing for cooler drilling and extended tool life.

Absolutely. While it works great in drill presses, the split point and durable body make it excellent for portable hand drilling applications where stability can be an issue.

The High Flow design optimizes the evacuation of metal chips from the hole, which prevents clogging and reduces heat buildup during the drilling process.

Yes, using a cutting lubricant like Walter Coolcut is highly recommended, especially when drilling stainless steel, to maximize the life of the bit.
