Precision taps are essential cutting tools used in machining to create or restore internal threads in a workpiece with high accuracy. Typically made from high-speed steel (HSS) or other hardened materials, these taps are designed to cut threads into a wide range of materials such as metals, plastics, and composites. Precision taps are vital for ensuring the compatibility of threaded components, like bolts or screws, within mechanical assemblies, where exact tolerances are required for both strength and function.

There are various types of precision taps, each designed for specific threading applications: hand taps, which are typically used manually for low-volume, controlled threading; machine taps, ideal for higher-volume production using machines like CNCs; and spiral-point taps, known for ejecting chips forward, making them suitable for deep hole tapping. Additionally, bottoming taps are used to thread holes with a flat bottom, while taper taps gradually create threads in pre-drilled holes with a conical end, perfect for starting new threads.

Precision taps come in various thread forms, including metric, imperial, and specialty thread profiles like BSP or NPT for pipe fittings. They are engineered to provide clean, consistent cuts without damaging the workpiece, ensuring that the threads formed are smooth and precise, minimizing friction, wear, and potential failures. For industries like aerospace, automotive, and manufacturing, where tolerances are tight, and the performance of threaded connections is critical, precision taps are indispensable tools for achieving consistent, high-quality results in production.
