Universal Radial Drill UR 50

Powerful – 50 mm drilling in steel at any angular direction.

ARSUN UR Series of Portable Universal Radial Drills are most suitable for drilling operations on heavy and sizable components which require quick and efficient preparations in terms of capacity as well as accuracy. Its drill head rotates 360º and swivels 90º up & 90º down on two planes. These rotational and swiveling movements make possible drilling operation at any angular direction.

Universal Radial Drill Machine - UR 50
All movement are motorized

  • Its various movements – i.e. arm up/down, arm horizontal traverse, 360º head rotation, head swiveling (90º up/down), column traverse along bed, sleeve locking/unlocking – all these movements are motorized, which offers fatigue free easy location while drilling.
  • It has wide range of 15-speeds and 6-feed rates makes the machine suitable for drilling, tapping and reaming operations within its full working range and various positions of arm and drill head.


  • Robust machine with easy operation.
  • Easily moveable, easily transportable.
  • Powerful : 50 mm drilling in steel at any angular direction.
  • The drilling head rotates 360º and swivels 90º up & 90º down.
  • Ideally suitable for large & stationary jobs, for drilling hard to reach places and on-site drilling.


This machine finds applications for drilling, reaming and tapping operations on components of large machine tools and forming machines, bulky parts of valves, pumps, turbines, generators, compressors, different kind of steel constructions, boilers, containers, chemical equipment, furnaces of cement plants, ship building, etc.
