PNEUMATIC AND HYDRAULIC THRUSTERS
Zagar Pneumatic and Hydraulic Thrusters series drilling units are capable of meeting a wide variety of production requirements. Available in three basic thrust sizes, they offer a solid solution for drilling operations. Requiring both rapid advance and controlled feed. The same unit features the choice of pneumatic or hydraulic operation, powered by a three- phase 230/460 V motor.
Zagar Tapping units incorporate a lead screw assembly with our standard drilling units. Tapping units are powered by a reversing brake motor. These serve a wide range of tapping applications, accommodating pitch sizes from 8 to 56 TPI (metric sizes also available) and motor sizes up to 7.5 HP.
