ARSUN UR Series of Portable Radial Drill with Universal Drill Head is most suitable for drilling operations on heavy and sizable components which require quick and efficient preparations in terms of capacity as well as accuracy.
Model UR 30 – Fixed Column Type
UR 30 is a fixed column type model in which column is bolted with base and has no traverse movement.
Its all movements are motorized like arm up/down, arm traverse, drill head swiveling (90º up/down), drill head 360º rotation, etc., which offer fatigue-free easy location while drilling. Only sleeve locking/unlocking is manual.
It has a wide range of 8-speeds and 5-power feeds makes the machine suitable for drilling, tapping, reaming operations within its full working range and various positions of arm and drill head.
Special Feature
- In this type of universal radial drill, the column is bolted with base and has no traverse movement.
- It has a wide range of 8-speeds and 5-power feeds with manual sleeve locking/unlocking function.

Working of Universal Radial Drill
Salient Features
- Heavy duty – 30mm drilling in steel at any angular direction.
- The drill-head rotates 360º and swivels 90º up & 90º down.
- Wide range of 8-speeds and 5-power feeds for drilling, tapping, and reaming operations.
- While depth drilling, auto feed disengages at preset depth and at too high drilling pressure.
- Arm up/down, arm traverse, head tilting, 360° head rotation etc. movements are motorized with easy pendant control.
- Well-adequately ribbed base, saddle, inner column, arms, skew bracket, and drill-head offer maximum rigidity and minimum deflection.
Application
This machine finds application for drilling, reaming, and tapping operations on components of large machine tools and forming machines, turbines, generators, compressors, different kind of steel constructions, boilers, containers, chemical equipment, furnaces of cement plants, ship- building etc.
