Features of KT-368B Pneumatic Multi-head Drills This equipment primarily is used for processing the through-hole or non-through-hole on the profiles of curtain wall and aluminum alloy. It may also used for the processing of industrial profiles and window profiles. Because of adopting the motor and the direct-ally style outputs of cylinder, as a result, drilling a hole more steady and the accuracy is high. This machine can pack to the head of clip-drill and the multi-head drills station, making drill a hole more convenient.
