Walter SST Power Tap 1"-8 UNC for Portable Drills

Reliable Threading Solution for Welders & Fabricators

When you are out in the field or working on a heavy fabrication project, you need tools that work as hard as you do. The Walter 1"-8 UNC SST Power Tap (03B661) is the ultimate solution for creating clean, precise threads using a reversible portable drill. Forget the frustration of broken taps and stripped threads; this heavy-duty power tap is built to withstand the high torque and instability often associated with handheld drilling operations.

Stop Breaking Taps

One of the biggest issues with tapping holes by hand or with a portable drill is keeping the tap straight. If the tap enters at an angle, it binds and snaps. Walter's innovative Power Tip design solves this by self-aligning the tap as it enters the hole. This feature allows you to start threads confidently and quickly, even in awkward positions. Furthermore, the tap is designed to push metal chips forward and out the other side of the hole, keeping the flutes clear and reducing the mechanical stress on the tool.

Master Stainless Steel

Stainless steel is notoriously difficult to tap due to its tendency to work-harden and generate high heat. The Walter SST Power Tap is specifically formulated to conquer these challenges. It features a proprietary SST surface coating that acts as a permanent lubricant, reducing friction and heat generation. This allows the tap to cut smoothly through stainless steel, mild steel, and aluminum without binding. For the best results, pair this tap with a high-quality cutting lubricant like Walter Coolcut.

Designed for Your Drill

Standard round-shank taps often spin inside the chuck of a powerful drill, ruining the shank and making the tap useless. This model features a 3-flat shank design that fits perfectly into standard drill chucks, guaranteeing a secure hold that won't slip under load. Increase your productivity and lower your cost per hole with a tap that is designed to last longer and perform better.
