Product Name: British and American machine extrusion Taps (all grinding) accuracy: H2
Material: high quality high speed tool steel (6542)
Application: suitable for processing zinc, copper alloy, Ti and Ti have no two.
Extrusion tap is the use of metal plastic deformation principle of a thread cutter and internal thread processing, extrusion extrusion tap internal threads are non chip processing technology, especially suitable for low strength, good plasticity and copper alloy Aluminum Alloy such as low hardness, large plastic materials tapping, long service life. With the extrusion tap extrusion thread surface finish, metal fiber thread is not broken, and form a layer of hardened layer on the surface, which can improve the strength and wear resistance of the thread. It fundamentally solves the problem of chip removal in tapping, because of no chips, more conducive to the assembly of threads.
