03B551 - Walter SST Power Tap 5/16-18 UNC for Portable Drills

Heavy-Duty Tapping Solution for Fabricators

For welders and metal fabricators, time is money, and stopping to hand-tap holes is a productivity killer. The Walter 03B551 SST Power Tap (5/16-18 UNC) is built to keep your project moving by allowing you to tap holes directly with your reversible portable drill. Gone are the days of struggling with tap wrenches and broken tools. This power tap is specifically formulated to handle the rigors of stainless steel and other tough metals commonly found in welding shops. Its robust construction ensures it can withstand the higher speeds and torque of power drilling without snapping, providing a reliable solution for creating threads in structural steel, aluminum plates, and custom fabrications.

Slippage in the drill chuck is a common frustration when using round-shank tools for heavy-duty tasks. Walter addresses this with a smart 3-flat shank that locks firmly into your drill's jaws. This means you can apply the necessary pressure to start the cut without the tool spinning inside the chuck. Additionally, the Power Tip geometry is a game-changer for through-hole applications. It pushes metal chips forward and out the other side of the hole, rather than pulling them back up the flutes. This prevents chip packing, which is the leading cause of tap breakage. The tip also helps self-align the tool with the hole, reducing the risk of cross-threading.

Durability is key in a welding environment. The Walter SST Power Tap features a special surface treatment that acts as a lubricant aid, keeping the cutting edges cool and sharp longer. This is particularly beneficial when working with work-hardening materials like stainless steel. The extra-long shank also gives you the clearance needed to reach into tight corners or through thick assemblies. Whether you are repairing damaged threads on equipment or fabricating new parts, this 5/16-18 UNC tap offers the speed, strength, and precision required to get the job done right the first time.
