03B554 - Walter 5/16-24 UNF SST High-Performance Power Tap

High-Performance Tapping for Portable Drills

The Walter 03B554 5/16-24 UNF SST Power Tap is a specialized cutting tool engineered to maximize productivity in industrial maintenance and fabrication environments. Unlike traditional hand taps that require a tap wrench and significant manual effort, this power tap is designed specifically for use with reversible portable power drills. This capability allows operators to tap holes significantly faster, reducing cycle times and labor costs associated with threading operations.

Technically, the tap features a unique "Power Tip" geometry. This design functions similarly to a spiral point tap, ejecting chips forward (ahead of the cut) rather than pulling them up the flutes. This is critical for through-hole applications, as it prevents chip packing that can lead to tap breakage. The tool is manufactured with a proprietary SST surface treatment, which provides enhanced lubricity and heat resistance. This treatment is particularly beneficial when working with difficult-to-machine materials such as stainless steel, where friction and heat buildup are common failure points for standard tooling.

To ensure compatibility with power tools, the shank is engineered with three precision-ground flats. This tri-flat design locks securely into standard drill chucks, preventing the tap from spinning or slipping under high-torque loads. The extended shank length also facilitates access to recessed areas or deep holes. Whether working on mild steel, aluminum, or stainless alloys, the Walter SST Power Tap delivers consistent, clean threads with the speed and convenience of power drilling.
