03A624 - Walter SST Power Tap 12-28 UNF for Stainless Steel

Fast, Reliable Threading on the Job Site

Stop wasting time with tap wrenches and slow hand-tapping methods. The Walter 12-28 UNF SST Power Tap is built to turn your reversible power drill into a high-speed threading machine. Designed for welders and fabricators who need to cut threads quickly and move on to the next task, this tap is tough enough to handle stainless steel without binding or breaking. If you are working on repairs, installations, or custom fabrication, this tool allows you to tap through-holes in seconds rather than minutes.

The secret to its ease of use is the Power Tip. When you press the tap into the hole, the tip helps align the tool automatically, ensuring your threads are straight every time. As it cuts, the spiral point pushes metal chips out the other side of the hole, keeping the flutes clear and reducing the resistance that snaps lesser taps. This makes it ideal for drilling through plates, tubing, and structural members where you have access to the back side of the hole.

Slipping in the chuck is a major frustration with standard taps, but Walter has solved this with a 3-flat shank design. The jaws of your drill chuck grip these flat surfaces securely, so the tap spins with the drill even under heavy torque. Coated with a special SST treatment to help it glide through sticky metals like aluminum and stainless, this 12-28 UNF tap is a must-have for any serious tool kit. It’s durable, fast, and designed to get the job done right the first time.
