Frequently Asked Questions
What is a radial drill and when is it needed compared to a pillar drill?
In a pillar drill, the workpiece moves to center the bit on the hole. In a radial drill, it's the spindle that moves: the radial arm moves along the column (height) and rotates around it (angle), bringing the spindle exactly over the drilling point on fixed, heavy workpieces that are not easily moved. It's the choice for large workpieces, metal fabrication, and machining on already assembled machines.
Is the radial arm motorized or manual?
It depends on the model. Basic versions of the RD series have manual arm movement with screw locking. NC or Vario versions may have Z-axis motorization. Check the model specifications in the technical table.
What is the purpose of right/left (R/L) spindle rotation?
Left (L) rotation allows the use of left-hand cutters and loosening left-hand threaded screws. It is also useful for manual tapping operations where advancement (right) and retraction (left) are alternated to break the chip.
Are spare parts and assistance available?
Original Bernardo spare parts available with 3–5 working days shipping. Italian customer assistance available.
How much space is needed for installation?
The turning radius of the arm determines the minimum operating area. Leave clear space equal to the arm's radius on all sides of the column. For machines over 500 kg, coordinate with Krollit for necessary unloading equipment.
