Bernardo Radial Drill RD 820 x 32 – Reliability and Precision for Versatile Machining
The Bernardo RD 820 x 32 radial drill is designed for drilling and tapping operations on medium-sized workpieces, ensuring robustness, precision, and ease of use. With a drilling capacity up to Ø 32 mm and tapping capacity up to M24, it is suitable for workshops and production departments that require flexibility.
The adjustable arm with electro-motorized lifting allows for quick positioning relative to the workpiece, while the smooth movement of the column ensures simple and precise adjustments. The 6-speed gearbox (75–1220 rpm) allows you to select the most suitable speed for the material and application.
The solid construction with a Ø 200 mm column, 250 mm spindle stroke, and 400 x 400 mm box table offer stability and support even for voluminous workpieces. Standard features include: coolant pump, LED lamp, lifting motor, and adjustable CE-compliant guard.

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, the spindle moves: the radial arm translates along the column (height) and rotates around it (angle), bringing the spindle exactly over the drilling point on fixed and heavy workpieces that are not easily moved. It is the choice for large workpieces, metal fabrication, and operations 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 the loosening of 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 business days shipping. Customer support available in Italian.
How much space is needed for installation?
The turning radius of the arm determines the minimum operating area. Leave free space equal to the arm's radius on all sides of the column. For machines over 500 kg, coordinate with Krollit for the necessary unloading equipment.
