03B561 - Walter SST Power Tap 3/8-16 UNC for Stainless Steel

Speed Up Fabrication with Reliable Tapping

For welders and fabricators, time is money, and stopping to hand-tap holes in a heavy steel frame is a productivity killer. The Walter 3/8-16 UNC SST Power Tap is built to keep your project moving. Unlike standard hand taps that are brittle and prone to snapping when used with power tools, this tap is specifically designed to withstand the torque and speed of reversible portable drills. Whether you are threading mounting holes on a custom bracket or repairing stripped threads on heavy machinery, this tool allows you to power through the job in seconds rather than minutes.

Working with stainless steel is a daily reality for many welders, and it is notoriously tough on cutting tools. This tap features Walter's exclusive SST surface treatment, which acts as a permanent lubricant shield. This means the tap cuts smoother, stays cooler, and lasts significantly longer, even in 304 or 316 stainless. You won't have to worry about the tap binding up or snapping off halfway through the plate. The "Power Tip" design is another huge advantage for fabrication work; it shoots the metal chips out the other side of the hole (through-hole application), keeping the threads clean and preventing the tap from jamming.

We know that drill chucks can struggle to hold onto round shanks under high torque. That is why this tap has three flat sides ground onto the shank, ensuring your drill gets a solid grip and never spins on the tool. It is the perfect addition to any welder's toolbox, turning a tedious manual task into a quick trigger pull. Use it on aluminum, mild steel, and stainless steel with confidence, and get back to welding sooner.
