03B073 - Walter 7/16-14 NC HSS Bottoming Tap for Blind Holes

Precision Threading for Blind Holes

The Walter 7/16"-14 NC Bottoming Tap (03B073) is a high-performance threading tool engineered for professional machinists and fabricators. Manufactured from premium High-Speed Steel (HSS), this tap is designed to withstand the rigors of industrial metalworking while maintaining a sharp cutting edge. The "bottoming" style features a very short chamfer, typically only 1 to 2 threads long, which allows the tool to cut threads almost entirely to the bottom of a blind hole. This capability is essential for applications where thread depth is critical and clearance is minimal.

Walter Surface Technologies is renowned for producing tools that prioritize precision and durability. This tap features precision-ground threads that reduce friction during the cutting process, resulting in cleaner, more accurate threads and less wear on the tool itself. The hardened and tempered construction ensures that the tap resists breakage and chipping, even when working with tough materials like stainless steel or mild steel. Whether you are tapping new holes in a fabrication project or repairing damaged threads in an MRO setting, this tool delivers the consistency required for high-quality results.

Versatility is a key strength of the Walter 03B073. It is compatible with a variety of materials, including aluminum, mild steel, and stainless steel. While it excels at finishing blind holes, it can also be used for through-holes where a specific thread fit is required. Pair this tap with a suitable tapping fluid to further extend its lifespan and ensure the smoothest possible operation.
