Walter SST Cobalt Stub Drill Bit for Stainless Steel and Sheet Metal

The Welder's Choice for Sheet Metal and Stainless

When you are in the middle of a fabrication project or a critical repair, the last thing you need is a drill bit that snaps the moment you apply pressure. The Walter SST Stub Drill is built specifically to solve this problem. Known in the industry for its rugged durability, this bit is a favorite among welders and fabricators who frequently work with sheet metal and stainless steel. The secret lies in its "stub" length design. By shortening the overall length and the flutes, Walter has created a bit that is far more rigid than standard bits. This means you can lean into your portable drill to get through a spot weld or a tough piece of stainless without the bit flexing and shattering.

Drill Stainless Steel with Confidence

Stainless steel is notorious for work-hardening and eating up standard high-speed steel bits. The Walter SST Stub Drill combats this with a premium cobalt blend construction. Cobalt allows the bit to withstand the intense heat generated when drilling hard metals, keeping the cutting edge sharp for longer. This is crucial for welders who need to prep surfaces for welding or drill out rivets and bolts. You spend less time sharpening or replacing bits and more time getting the job done. The bronze surface treatment further aids the process by lubricating the cut and preventing chips from welding to the bit.

Precision and Speed in the Shop

Time is money in any welding shop. The Walter SST Stub Drill features a split point tip that bites into the metal immediately upon contact. You won't waste time fighting the drill or worrying about it wandering across your workpiece and scratching the finish. This self-centering action is perfect for drilling out spot welds on auto body panels or creating precise holes in HVAC ducting. Whether you are working on a bench or in an awkward position under a chassis, the stability and bite of this drill bit give you the control you need. Add the Walter SST Stub Drill to your arsenal and experience the difference a professional-grade tool makes.
