03B564 - Walter 3/8-24 UNF SST Power Tap for Through Holes

High-Performance Threading with Walter SST Power Taps

The Walter 03B564 3/8-24 UNF SST Power Tap is an industrial-grade threading tool engineered to transform the efficiency of metal fabrication and maintenance operations. Unlike traditional hand taps that are prone to breakage when used with power tools, the SST Power Tap is specifically designed to withstand the higher torque and speed of reversible portable drills. This capability allows for a dramatic reduction in cycle time per hole, making it an essential asset for high-volume production environments and time-sensitive repair work.

At the core of its performance is the proprietary SST surface treatment. This advanced coating significantly reduces friction between the tool and the workpiece, minimizing heat generation and preventing galling—a common issue when tapping stainless steel and other tough alloys. The tap features a specialized "Power Tip" geometry, which functions similarly to a spiral point tap. This design actively ejects chips forward ahead of the cutting action, preventing chip packing in the flutes. Consequently, this tap is optimized for through-hole applications where chip evacuation is critical for maintaining thread quality and tool longevity.

Operational stability is ensured through a thoughtfully designed shank featuring three precision-ground flats. This tri-flat configuration locks securely into standard drill chucks, eliminating the frustration of the tool spinning or slipping under load. Furthermore, the tap incorporates a self-aligning lead that helps the operator establish the correct angle immediately upon contact, ensuring threads are cut true to the hole axis. Whether working with mild steel, aluminum, or challenging stainless steel grades, the Walter SST Power Tap delivers consistent, high-quality threads with the speed and convenience of power tooling.
