Walter 5/8-18 UNF High Performance Power Tap for Stainless Steel

Blast Through Stainless with Your Power Drill

Stop wasting time turning a tap wrench by hand. The Walter 03B604 5/8-18 UNF SST Power Tap is built to let you use your reversible power drill for threading jobs, getting you back to welding and fabrication faster. Standard taps often snap or dull instantly when you put them in a drill, especially on stainless steel. Walter has solved this with their SST Power Tap series. These tools are tough, heat-resistant, and designed to handle the speed and torque of power tools without failing halfway through the hole.

No More Spinning in the Chuck

We've all been there: you're halfway through a thread, the tap bites hard, and suddenly your drill chuck is spinning while the tap stays stuck. It ruins the shank and ruins your day. This Walter tap features a specially designed shank with three flat sides. When you tighten your drill chuck, the jaws bite onto these flats, locking the tool in place. This means 100% of your drill's power goes into cutting the thread, giving you the torque you need to drive through thick steel plate or heavy-wall tubing.

Self-Aligning and Chip Clearing

Starting a tap straight with a hand drill can be tricky. The Walter 03B604 features a "Power Tip" that helps self-align the tool with the hole, so you don't end up with crooked threads. Once it starts cutting, the geometry pushes the metal chips forward, out the other side of the hole. This is crucial because it keeps the flutes clear. If chips get packed in the flutes, that's when taps snap. By ejecting them forward, this tap keeps cutting freely, making it the perfect choice for through-holes on flanges, brackets, and structural steel.

Built for the Shop and the Field

Whether you are repairing stripped threads on a piece of heavy equipment or fabricating a custom stainless assembly, this tap is a must-have in your toolbox. It works on aluminum, mild steel, and stainless steel with equal ease. The SST surface treatment acts like a permanent lubricant, keeping the cutting edges cool and sharp longer than uncoated tools. Upgrade your tapping game and stop doing it the hard way—let your drill do the work with Walter.
