03B571 - Walter 7/16-14 UNC SST High-Performance Power Tap for Stainless Steel

High-Performance Threading with Walter SST Power Taps

The Walter 03B571 7/16-14 UNC SST Power Tap is a premium cutting tool engineered to transform the way industrial professionals approach threading operations. Designed specifically for use with reversible portable drills, this power tap bridges the gap between manual hand tapping and stationary machine tapping. It is constructed to handle the rigors of heavy-duty metalworking, providing a reliable solution for creating internal threads in a wide variety of materials, including mild steel, aluminum, and difficult-to-machine stainless steel.

At the core of its performance is the proprietary SST surface treatment. This advanced coating significantly reduces friction at the cutting edge, minimizing heat generation and preventing galling—a common issue when tapping softer or gummy metals. The reduction in friction not only produces a cleaner thread profile but also extends the lifespan of the tool, making it a cost-effective choice for high-volume maintenance and fabrication environments. The tap features a specialized "Power Tip" geometry, which functions similarly to a spiral point tap. This design ejects chips forward, ahead of the cutting action, effectively preventing chip packing that can lead to tap breakage, especially in through-hole applications.

One of the standout features of the Walter SST Power Tap is its three-flat shank design. Standard round shanks often slip inside drill chucks under high torque, damaging both the tool and the workpiece. The three-flat geometry ensures a positive lock within the chuck jaws, guaranteeing maximum torque transmission and safety. Additionally, the self-aligning tip assists the operator in starting the thread straight, reducing the risk of cross-threading. Whether you are repairing damaged threads in the field or fabricating new components, the Walter 03B571 delivers precision, speed, and durability.

Key Technical Benefits

This tool is optimized for through holes where chips can exit the bottom of the workpiece. The long shank design also provides extra reach, allowing access to recessed areas that standard taps cannot reach. By enabling the use of power tools for tapping, this product significantly reduces operator fatigue and increases productivity compared to traditional hand tapping methods.
