Walter SST+ 7/16" Drill Bit with 3/8" Reduced Shank

Drill Bigger Holes with Your Standard Drill

Fabricators and welders often face the challenge of needing to drill a hole larger than their portable drill's chuck can accept. The Walter 01R228 solves this problem instantly. This is a 7/16-inch drill bit that has been precision-machined with a 3/8-inch reduced shank. This means you can pop this heavy-duty bit directly into your standard 3/8-inch drill chuck and get to work, without needing to drag out a heavy 1/2-inch drill or a drill press. It is the ultimate convenience tool for mobile welding rigs and field repair kits.

But convenience isn't the only benefit; this bit is built tough. It features Walter's renowned SST+ performance geometry. If you work with stainless steel, you know how easily standard bits can burn up or dull. The SST+ design utilizes a cobalt-blended high-speed steel formula (or equivalent high-performance geometry) with a 135-degree split point. This split point bites into the metal instantly, requiring less force from you to start the cut. It is perfect for drilling out broken bolts, preparing rivet holes, or fabricating brackets in hard materials.

The self-centering nature of the 135° point is a game-changer when working on curved surfaces like roll cages, handrails, or exhaust tubing. You won't have to worry about the bit slipping and marring the finish. The robust web construction adds rigidity, preventing the bit from snapping under the torque required to drill 7/16-inch holes in steel.

Upgrade your toolbox with the Walter 01R228. It combines the capacity you need with the compatibility you already have. Stop struggling with inferior bits that wander and dull quickly. Choose the bit designed for the professional welder who needs to drill accurate holes in stainless and mild steel efficiently, every single time.
