03B544 - Walter 1/4-28 UNF High-Performance Power Tap for Stainless Steel

High-Performance Tapping for Industrial Maintenance

The Walter 1/4-28 UNF SST Power Tap (03B544) is engineered to transform the way maintenance professionals and machinists approach threading operations. Unlike traditional hand taps that are prone to breakage and misalignment when used with power tools, this specialized power tap is designed explicitly for reversible portable drills. It addresses the common pain points of on-site thread repair and fabrication, offering a robust solution that significantly reduces tapping costs while enhancing productivity.

At the core of its performance is the proprietary SST surface treatment. This advanced coating provides exceptional lubricity, reducing friction and heat generation during the cutting process. This is particularly critical when working with tough materials like stainless steel, where work-hardening can destroy standard tools. The tap features a unique "Power Tip" geometry which serves a dual purpose: it acts as a pilot to self-align the tap with the hole axis for perfect threads every time, and it forcefully ejects chips ahead of the cutting action. This chip-clearing capability makes it ideal for through-holes, ensuring that debris does not clog the flutes or cause the tap to bind and snap.

Reliability is further ensured by the three-flat shank design. Standard round shanks often spin inside the drill chuck under high torque, damaging both the tool and the chuck. The Walter SST Power Tap locks securely into place, guaranteeing positive drive transmission even under heavy loads. Whether you are repairing damaged threads in the field or fabricating new components in the shop, this tool delivers speed, precision, and durability that standard taps cannot match.

Key Technical Benefits

• Self-Aligning: The Power Tip guides the tap into the hole, eliminating cross-threading.
• Chip Management: Spiral point geometry pushes chips forward, keeping the cutting path clear.
• Secure Grip: Designed to fit standard drill chucks without slipping.
• Versatile Material Use: Excellent performance on mild steel, stainless steel, and aluminum.
