Applications
This tap is used in the industrial manufacturing of components made from non-ferrous metals. It is suitable for thread cutting in wrought aluminum alloys, cast aluminum alloys with a silicon content below 12%, as well as in copper and brass. Due to its geometry, it is specifically aligned for machining through holes.
Special features
The construction featuring three flutes creates favorable conditions for an even cut and high surface quality in the thread profile. The employed HSS-E cutting material supports efficient workflows in professional machining operations, even at higher cutting speeds.
