Walter SST+ 17/32" Drill Bit, 3/8" Reduced Shank, 135° Split Point

Drill Bigger Holes with Your Standard Drill

Every welder and fabricator has been there: you need to drill a hole just slightly larger than a half-inch, but your cordless drill only has a 3/8-inch chuck. Instead of wasting time hunting for a heavy-duty drill or dragging the workpiece over to the drill press, reach for the Walter 01R234 SST+ Drill Bit. This 17/32-inch bit is designed with a turned-down 3/8-inch shank, making it universally compatible with the standard drills you already have in your toolbox. It is the ultimate problem-solver for field work and quick shop fixes.

But this bit isn't just about fitting in the chuck; it's about performance. If you work with stainless steel, you know how quickly it can chew up cheap drill bits. The Walter SST+ series is built tough to handle the heat and hardness of stainless steel without dulling instantly. The secret is in the geometry and the high-quality material construction, which allows the bit to shear through metal rather than rubbing against it. This means you get cleaner holes faster, and you burn through fewer bits over the course of a project.

Starting a hole on a smooth metal surface can be a headache, especially on round tubing or pipe. The 01R234 features a 135-degree split point tip that acts like a built-in anchor. As soon as you pull the trigger, the tip centers itself and starts cutting. You don't need to waste time hammering a center punch mark or worrying about the bit skidding across your finished surface and leaving scratches. It stays where you put it.

Whether you are drilling out rivets, making clearance holes for bolts, or fabricating custom brackets, this bit gives you the power of a large-diameter cutter with the convenience of a standard hand tool. It cuts mild steel, aluminum, and stainless with equal ease. Add the Walter 17/32" SST+ bit to your arsenal and stop letting chuck size limit your capabilities.
