03A103 - Walter 10-24 NC HSS Bottoming Tap

Precision Threading for Industrial Applications

The Walter 10-24NC Bottoming High-Speed Steel (HSS) Tap (SKU: 03A103) is an essential cutting tool designed for professional machinists and fabricators who demand accuracy and longevity. Manufactured from premium high-speed steel, this tap is engineered to withstand the high thermal and mechanical stresses associated with cutting threads in hard metals. Unlike standard taper or plug taps, this bottoming tap features a very short chamfer length of just 1 to 2 threads. This specific design characteristic makes it the ideal choice for threading blind holes—holes that do not go all the way through the workpiece—allowing you to cut threads as close to the bottom of the hole as possible.

Walter Surface Technologies has developed this tool with precision ground threads that have been meticulously hardened and tempered. This manufacturing process ensures that the cutting edges remain sharp longer, reducing the torque required to cut threads and minimizing the risk of tap breakage. Whether you are working with aluminum, mild steel, or stainless steel, the 03A103 delivers clean, precise Class 2B threads every time. It is compatible with standard tap handles and tapping machines, making it a versatile addition to any industrial tool crib.

For optimal performance, it is recommended to use this bottoming tap after a taper or plug tap has been used to start the thread, especially in tougher materials. This sequential approach reduces wear on the bottoming tap and ensures the highest quality thread profile. Trust Walter's legacy of high-performance cutting tools to maintain the efficiency and quality of your production lines.
