ARSUN UR Series of Portable Radial Drill with Universal Drill Head is most suitable for drilling operations on heavy and sizable components that require quick and efficient preparations in terms of capacity as well as accuracy.
Model UR 50 – Column Traverse Type
UR 50 is a column traverse type model in which its column traverses along the bed.
Arm up/down, arm traverse, 360º head rotation, drill-head swiveling (90º up/down), column traverse along the bed, sleeve lock/unlock – all movements are motorized, which offers fatigue-free easy location while drilling.
It has a wide range of 15-speeds and 6-power feeds makes the machine suitable for drilling, tapping and reaming operations within its full working range and various positions of arm and drill head.
