03B591 - Walter SST Power Tap 9/16-12 UNC for Stainless Steel and Steel

High-Performance Tapping for Industrial Fabrication

The Walter 03B591 SST Power Tap (9/16-12 UNC) represents a significant leap forward in threading technology for MRO and fabrication environments. Designed explicitly to bridge the gap between manual hand tapping and stationary CNC machining, this tool empowers operators to utilize reversible portable drills for creating high-quality threads in the toughest materials. Traditional hand tapping is a time-consuming bottleneck in production, often fraught with operator fatigue and tool breakage. The Walter SST Power Tap eliminates these issues by allowing for high-speed, torque-driven tapping directly at the assembly site.

At the core of this tool's performance is the proprietary SST surface treatment. This advanced coating drastically reduces the coefficient of friction between the tap and the workpiece. In metals like stainless steel, where heat generation and galling are primary failure modes, the SST treatment ensures smooth rotation and cleaner thread formation. This lubricity not only extends the life of the tap but also reduces the load on the power drill, preserving the longevity of your power tools.

Structurally, the tap is engineered to handle the unique stresses of handheld power operation. It features a specialized "Power Tip" geometry that serves two critical functions: it self-aligns the tap with the hole axis to prevent cross-threading, and it ejects chips forward ahead of the cut. This forward chip evacuation is essential for through-hole applications, preventing chip packing that can snap taps. Furthermore, the shank is machined with three distinct flats. This tri-flat design locks securely into standard drill chucks, completely eliminating the risk of the tap spinning inside the chuck under high torque loads. Whether you are repairing damaged threads in the field or fabricating new components in the shop, the Walter 03B591 delivers reliability, speed, and precision.
