Ppiral flute are cutting tools for machining internal threads, with grooves along the axial direction. Also known as a Screw tap. Taps are classified according to their shape as easy to process for spiral flute, with slightly lower accuracy and larger output. Generally used for thread machining on ordinary lathes, drilling machines, and tapping machines, with slow cutting speeds. spiral flute are commonly used for drilling blind holes in CNC machining centers, with fast processing speed, high precision, good chip removal, and good alignment. The front part of the screw tap has a groove for machining through holes. Most of the taps provided by tool factories are coated taps, which have significantly improved service life and cutting performance compared to uncoated taps.

Drill bit tap are a new type of threading tool that uses the principle of metal plastic deformation to process internal threads. Squeezing internal threads in Thread tap is a chip free machining process, especially suitable for copper alloys and aluminum alloys with low strength and good plasticity. It can also be used for tapping materials with low hardness and high plasticity such as stainless steel and low carbon steel, with a long service life. The surface smoothness of the threads extruded by spiral flute is high, the metal fibers of the threads do not break, and a cold hard layer is formed on the surface, which can improve the strength and wear resistance of the threads. It fundamentally solves the problem of chip removal in tapping, and due to the absence of chips, it is more conducive to thread assembly. Widely used in the electronics and plastics industries.

Used for processing ordinary internal threads on nuts or other components (i.e. tapping) machine tap usually refers to high-speed steel grinding tap, suitable for tapping on machine tools; Hand tap refers to a carbon tool steel or alloy tool steel rolling (or cutting) tap, suitable for Manual tapping.
