Product Description
Machine tap with reinforced shank, for through threads in aluminium, aluminium alloys, bronze,copper, nickel and plastics.
- To cut an internal thread, at first a core hole is drilled, whose diameter is approximately smaller by the pitch of the thread than the nominal diameter of the thread.
- Subsequently tapered counter bores are placed,which match the size of the thread diameterplus 10% of it. This is done to get a better insertion into the bore hole and to prevent the first and the last thread from being pushed out when beginning to cut.
- Then the taps are screwed in and out in order.The final core hole diameter is created through the additional plastic deformation of the thread flanks.
The Spiral Point machine tap consists of cobalt alloyed and vaporised heavy duty high-speed steel. For through threads and bottoming threads in unalloyed and alloyed steels up to a strength of 1000 N/mm², staniless steel, malleable cast iron and non-ferrous metals. The thread is cut inone operation.
