03B644 - Walter 7/8-14 UNF SST High-Performance Power Tap for Stainless Steel

High-Performance Tapping for Industrial Applications

The Walter 03B644 7/8-14 UNF SST Power Tap is a precision-engineered cutting tool designed to revolutionize threading operations in industrial environments. Unlike traditional hand taps that require manual effort and significant time, this SST Power Tap is specifically constructed for use with reversible portable drills. This capability allows operators to tap holes rapidly and efficiently, drastically improving productivity in maintenance, repair, and fabrication settings.

At the core of its performance is the proprietary SST surface treatment, which enhances lubricity and reduces friction during the cutting process. This is critical when working with hard-to-machine materials such as stainless steel, where heat generation and galling are common issues. The tap features a specialized "Power Tip" geometry that serves two functions: it self-aligns the tap with the hole axis to ensure straight threads, and it mechanically ejects chips forward (ahead of the tap). This chip evacuation method makes it ideal for through-holes, preventing chip packing that often leads to tool breakage.

To address the common problem of slippage in drill chucks, Walter has designed this tap with three precision-ground flats on the shank. This ensures positive torque transmission even under heavy loads. Whether working with mild steel, aluminum, or tough stainless alloys, the Walter SST Power Tap delivers consistent, high-quality threads with extended tool life.
