Walter 7/8-14 UNF SST High-Performance Power Tap for Stainless Steel

Stop Hand Tapping and Start Drilling

For welders and fabricators, time is money, and hand-tapping holes is one of the slowest parts of the job. The Walter 7/8-14 UNF SST Power Tap (03B644) is built to solve that problem. Designed specifically to be used with your reversible hand drill, this tool lets you power through threading jobs in seconds rather than minutes. It is tough enough to handle stainless steel—a material that eats up lesser taps—making it an essential addition to any fabricator's toolkit.

We know the frustration of a tap spinning in the chuck just when you need torque. That’s why this Walter tap features a shank with three flat sides, locking it securely into your drill's jaws so it won't slip. The "Power Tip" design is another game-changer for field work; it pushes chips out the other side of the hole, keeping the flutes clear and reducing the chance of the tap binding or snapping off inside your workpiece.

Whether you are repairing damaged threads on a piece of heavy equipment or fabricating new assemblies in the shop, this tap handles mild steel, aluminum, and stainless with ease. It aligns itself as it starts, so you get straight threads without the wobble. Upgrade your workflow and leave the tap wrench in the drawer.
