ARSUN has developed a Portable Radial Drill with Universal Drill-head, which is designed to offer rigidity, precision and flexibility to drill at any angular direction. The drill head swivels on 2 planes - 90º Up & 90º Down, and its 360º rotational movement makes possible the drilling operation at any angular direction. The model UR50 is having 50-mm drilling capacity in steel.

Its Arm Up/Down movement, Arm Traverse movement, Drill-Head Swiveling (90º up/down) movements, column traverse movement along bed - all movements are motorized, which offers fatigue free easy location while drilling.

It has wide range of 15-speeds and 6-power feeds makes the machine suitable for drilling, tapping, reaming operations within its full working range and various positions of arm and drill head.

This machine is designed for drillling, reaming and tapping operations on components of large machine tools and forming machines, turbines, generators, compressors, different kind of steel constructions, boilers, containers, chemical equipments, furnases of cement plants, ship building, etc.


Salient Features

  • Heavy duty – 50mm drilling in steel at any angular direction.
  • The drill-head rotates 360º and swivels 90º up & 90º down.
  • Wide range of 15-speeds and 6-power feeds for drilling, tapping and reaming operations.
  • While depth drilling, auto feed disengages at preset depth (positive stop) and at too high drilling pressure.
  • Arm up/down, arm traverse, head tilting, head swiveling, column (sleeve) locking and column traverse on bed – all movements are motorized with easy remote control.
  • Rapid travel for column movement on bed, arm traverse and arm up/down movement.
  • Remote control of all machine functions including elevating, traversing, tilting and sleeve locking operations from pendent control.
  • Well adequately ribbed bed, saddle, inner column, arms and drill-head offer maximum rigidity and minimum deflection.
  • Extra rigid machine ideally suitable for large & stationary jobs and for site drilling work.
