03B561 - Walter SST Power Tap 3/8-16 UNC for Stainless Steel

High-Performance Threading for Industrial Applications

The Walter 03B561 SST Power Tap (3/8-16 UNC) represents a significant leap forward in threading technology, specifically engineered to bridge the gap between manual precision and power tool efficiency. Designed for use with reversible portable drills, this tool eliminates the slow, labor-intensive process of hand tapping, allowing operators to cut threads rapidly without sacrificing quality. The core of its performance lies in the proprietary SST surface treatment, a specialized coating that drastically enhances lubricity. This reduction in friction is critical when working with difficult materials like stainless steel, as it minimizes heat generation and prevents the galling that often leads to tool failure.

Structurally, the tap features a robust shank equipped with three precision-ground flats. This design consideration addresses a common frustration in field machining: bit slippage. By locking securely into the drill chuck, the tap ensures 100% torque transmission, even under heavy loads. Furthermore, the extended shank length provides the reach necessary for tapping deep holes or accessing recessed areas that standard taps cannot reach. The tool is manufactured from premium high-speed steel, ensuring it maintains its cutting edge through repeated cycles in ferrous and non-ferrous metals.

A standout feature of this model is the "Power Tip" mechanism. This innovative geometry serves a dual purpose: it acts as a pilot to self-align the tap with the hole axis, ensuring perfectly straight threads every time, and it functions as a spiral point to eject chips forward. By pushing swarf ahead of the cutting action, the flutes remain clear, reducing the risk of clogging and breakage. This makes the Walter SST Power Tap an indispensable asset for maintenance, repair, and operations (MRO) professionals seeking reliability and speed.
