Carbide tap, forming tap, Forming roll tap without male center.
Carbide forming taps, this tap is a new type of thread tapping tool which uses metal plastic deformation principle to tap internal thread. Forming is a chip free tapping technology, especially suitable for tapping copper alloy and aluminum alloy with low strength and good plasticity, and materials with low hardness and high plasticity, such as stainless steel and low carbon steel, with long service life.

product picture:
Same as the carbide cutting tools gradually replaces the high speed steel tools in turning, cemented carbide taps also begin to be more and more used for thread hole tapping. Compared with HSS taps, cemented carbide taps have high hardness and brittleness, so there is a problem of chip removal when tapping with cemented carbide taps. In spite of this, cemented carbide taps are super good for tapping cast iron and aluminum alloy materials,tap damage form is mainly mechanical wear out. Because a large number of cast iron and aluminum alloy parts are applied in the automotive industry, carbide taps are used more and more wider to obtain long tool life. In the automotive industry, the reduction of the tool replacing time is obviously an important factor, and the long tool life of cemented carbide taps will minimize the time for replacing taps. The performance of coated cemented carbide taps with small helix angle is very good to tap aluminum alloy workpiece with silicon content of 8% - 12%. The tap made of sub-micron grain cemented carbide can increase the toughness without reducing its hardness. It is very good in tapping hardened steel, plastics and difficult to machine nickel base alloy.
