Walter SST+ 9/16" Drill Bit - 3/8" Reduced Shank

Drill Larger Holes with Your Standard Drill

Fabricators and welders often face the challenge of needing to drill a hole larger than the capacity of their portable drill's chuck. The Walter 9/16" SST+ Drill Bit (01R236) solves this problem with its clever 3/8" reduced shank design. This feature allows you to chuck a 9/16" diameter bit into a standard 3/8" drill, giving you the versatility to tackle larger hole requirements without needing to upgrade your power tools or drag out a heavy magnetic drill. It is the perfect problem-solver for field repairs, truck maintenance, and on-site installation work.

Don't let the convenience fool you; this is a serious industrial tool. Built with Walter's SST+ technology, this bit is made to eat through stainless steel. If you've ever burned out a hardware store bit trying to get through a stainless sheet, you know the frustration. This bit uses a heavy-duty HSS formulation that resists heat buildup, keeping the cutting edge sharp longer. The 135-degree split point bites into the metal immediately, so you aren't skating across the surface scratching up your workpiece. It centers itself, letting you drill straight, true holes with less feed pressure.

Whether you are working on mild steel, aluminum, or tough stainless alloys, this bit performs. The spiral flute design efficiently clears chips from the hole, preventing binding and overheating. Add the Walter 01R236 to your toolbox and ensure you are ready for those jobs that demand a little extra size and a lot of extra toughness.
