03B551 - Walter SST Power Tap 5/16-18 UNC for Portable Drills

Maximize Tapping Efficiency with Walter SST Technology

The Walter 03B551 SST Power Tap represents a significant leap forward in industrial threading operations. Designed explicitly to replace the slow and laborious process of manual hand tapping, this tool is engineered for use with reversible portable drills. By leveraging the torque and speed of power tools, the SST Power Tap allows operators to cut threads in a fraction of the time required by traditional methods. This specific model features a 5/16-18 UNC thread size, making it a versatile addition to any maintenance, repair, or fabrication toolkit. Whether working with mild steel, tough stainless steel, or non-ferrous alloys like aluminum, this tap delivers consistent, high-quality threads with minimal effort.

One of the standout features of the Walter SST line is the 3-flat shank design. Standard round shanks often suffer from slippage under high torque, damaging the tool and the workpiece. Walter has eliminated this issue by grinding three distinct flats onto the shank, ensuring a positive lock within the drill chuck. This secure fit translates to better power transmission and greater safety for the operator. Furthermore, the tap is constructed with a long, sturdy shank, providing the reach necessary to tap deep holes or access recessed areas that standard taps cannot reach.

Performance is further enhanced by Walter's proprietary surface treatment and the innovative Power Tip. The specialized surface coating reduces friction and heat generation, which is critical when tapping hard materials like stainless steel. The Power Tip is designed to eject chips ahead of the tap, clearing the path for the cutting edges and preventing the tool from binding or breaking in through-holes. This self-aligning feature also helps ensure the tap follows the correct axis, resulting in precise, straight threads every time. For industrial professionals seeking to reduce downtime and tool costs while increasing throughput, the Walter 03B551 is the superior choice.
