Walter SST+ 15/32" Drill Bit with 3/8" Reduced Shank

Heavy-Duty Walter Drill Bit for Stainless & Steel

When you are out on the job site or in the welding shop, you need a drill bit that bites hard and doesn't quit. The Walter 15/32" SST+ Drill Bit (SKU: 01R230) is built for welders and fabricators who need reliable performance in tough metals. One of the biggest frustrations in the field is needing to drill a hole slightly larger than your drill's chuck can handle. This bit solves that problem with its 3/8" reduced shank, allowing you to drive a 15/32" bit using a standard 3/8" chuck portable drill. It’s a simple, practical solution that expands the capabilities of your existing power tools without requiring an upgrade to a heavy-duty 1/2" drill.

Time is money, and the SST+ split point design saves you both. The 135° point angle is self-centering, meaning it starts cutting the moment it touches the metal. You won't have to worry about the bit skating across your workpiece and scratching the finish, nor will you need to waste time hunting for a center punch. This aggressive cutting action requires less force from you, making it easier to drill through thick steel plate, stainless steel brackets, or aluminum piping overhead or in awkward positions. The bit cuts clean and fast, leaving you with a professional hole ready for tapping or bolting.

Walter Surface Technologies is known for producing top-tier industrial consumables, and their drill bits are no exception. This bit is formulated to resist the high heat generated when drilling stainless steel, a common failure point for standard hardware store bits. By maintaining its hardness at high temperatures, the SST+ bit offers a longer service life, meaning fewer trips to the tool crib and more time making sparks. Whether you are fabricating custom parts, repairing heavy machinery, or installing structural components, the Walter 01R230 gives you the edge you need to get the job done right.
