03B581 - 1/2-13 UNC SST Power Tap for Portable Drills

Stop Hand Tapping and Start Drilling

Let's face it: hand tapping is a pain. It’s slow, it’s tiring, and one wrong move can snap a tap off in your workpiece. The Walter 1/2-13 UNC SST Power Tap (03B581) changes the game for fabricators and welders. Designed specifically to be used in your reversible hand drill, this tool lets you power through threading jobs in seconds rather than minutes. Whether you are tapping holes in a mounting plate or cleaning up threads on a repair job, this tap is built to handle the speed and torque of power tools.

The secret is in the design. Walter equipped this tap with a "Power Tip" that acts like a pilot, helping you align the hole instantly. As you drill, the tip pushes chips forward and out the other side, so you don't have to worry about backing off every turn to break chips. This makes it perfect for through-holes in tough metals. Speaking of tough, the SST surface treatment makes this tap slick and durable, allowing it to cut through stainless steel like butter without binding or overheating.

One of the biggest frustrations with using round-shank tools in a drill is slippage. When the going gets tough, the chuck spins, and the tap stays still. Walter solved this with a 3-flat shank design that locks solid into your drill chuck. You get 100% power transfer with zero slip. If you work with steel, stainless, or aluminum and want to speed up your workflow, put away the tap wrench and grab a Walter SST Power Tap.
