HSS Hand Tap Set – Taper, Plug & Bottoming Taps is a complete threading solution designed for accurate and efficient internal thread cutting in metal, steel, aluminum, and other machinable materials. Manufactured from high-speed steel (HSS), these taps offer excellent strength, wear resistance, and long tool life for workshop and industrial use.

• Taper Tap features a long, gradual lead for easy alignment and smooth thread starting. It is used first to initiate threads, especially in new or unthreaded holes.
• Plug Tap has a medium lead and is used for general-purpose threading, following the taper tap to deepen and refine the threads.
• Bottoming Tap has a short lead and is used last to cut threads close to the bottom of blind holes, ensuring full thread depth.

Together, these three taps are used sequentially to produce clean, accurate threads with better control and reduced tool stress, making the set ideal for machining, maintenance, fabrication, and repair applications.
