03A624 - Walter SST Power Tap 12-28 UNF for Stainless Steel

High-Performance Tapping for Industrial Fabrication

The Walter 12-28 UNF SST Power Tap (03A624) represents a significant leap in threading efficiency for industrial maintenance and fabrication. Engineered specifically to leverage the torque and speed of reversible portable drills, this tool eliminates the labor-intensive process of hand tapping. It is meticulously designed to handle the rigors of tapping tough materials, including stainless steel, mild steel, and various non-ferrous alloys, making it an indispensable asset for MRO professionals seeking to reduce cycle times.

At the core of its performance is Walter's proprietary SST surface treatment. This advanced coating significantly enhances lubricity, reducing heat generation and friction during the cutting process. This is critical when working with work-hardening materials like stainless steel, ensuring the tap maintains its cutting edge longer than standard uncoated tools. The tap also features a specialized Power Tip mechanism. This innovative design element serves two functions: it acts as a pilot to self-align the tap with the hole axis for precision threading, and it actively evacuates chips forward (ahead of the tap). This chip evacuation is crucial for through-hole applications, preventing chip packing that can lead to tap breakage.

Operational stability is guaranteed by the shank design, which incorporates three ground flats. These flats ensure a positive lock within standard drill chucks, completely eliminating the slippage that often occurs with round-shank taps under load. Whether repairing damaged threads or fabricating new assemblies, the Walter SST Power Tap delivers speed, precision, and durability, effectively lowering the overall cost per tapped hole.
