03B081 - Walter 1/2-13 NC HSS Taper Tap

Precision Threading with Walter HSS Taper Taps

The Walter 03B081 1/2-13NC Taper Tap is a premium cutting tool designed for creating internal threads with exceptional accuracy and surface finish. Manufactured from high-grade High Speed Steel (HSS), this tap is engineered to withstand the thermal stresses of continuous industrial use while maintaining a sharp cutting edge. The precision-ground threads ensure tight tolerances, making it an ideal choice for critical assembly work where fastener fitment is paramount.

Taper taps are specifically designed with a pronounced chamfer (typically 7 to 10 threads) to assist in starting the thread square to the hole. This feature distributes the cutting load across more teeth, reducing the torque required to start the cut and minimizing the risk of breakage. This makes the Walter 03B081 particularly effective for starting new threads in through-holes or for tough materials where gradual cutting action is beneficial. The hardened and tempered structure of the HSS body provides the rigidity needed to resist deflection, ensuring straight, true threads every time.

Whether working with mild steel, stainless steel, or aluminum, this tap delivers consistent performance. Its flute design effectively evacuates chips, preventing clogging and thread damage. For maintenance and repair operations (MRO), having a reliable taper tap like this is essential for cleaning up damaged threads or fabricating new components. Walter's commitment to quality ensures that this tool offers a long service life, reducing the frequency of replacement and downtime in your machining operations.
