FLUTE GEOMETRIES
STRAIGHT FLUTES These taps are used on steels with normal strength and toughness (R=750 N/mm 2 ) as well as on short-chipping abrasive materials (grey cast iron, bronze, etc.).
SPIRAL FLUTES, 15° RIGHTHAND SPIRAL These taps improve chip evacuation and are well suited when tapping blind holes of medium depth on tough materials.
SPIRAL FLUTES, 40°/45° RIGHTHAND SPIRAL The high helix angle ensures the evacuation of chips from deep blind holes.
SPIRAL FLUTES, 40° RIGHTHAND SPIRAL, FOR LIGHT ALLOYS The large flutes and high helix angle ensure efficient chip removal on long-chipping light alloys such as aluminium.
