THRUSTER TAPPING UNITS
Tight tolerances for a wide range of tapping operations
Zagar thruster tapping units incorporate a lead screw assembly with our standard drilling units. Tapping units are powered by a reversing brake motor. These units serve a wide range of tapping applications, accommodating pitch sizes from 8 to 56 T.P.I. (metric sizes also available) and motor sizes up to 7.5 hp.
