Bernardo SRB 50 NC Radial Drilling Machine
The Bernardo SRB 50 NC radial drilling machine is a high-end machine, designed for professional drilling and threading applications up to M36. The Bohtronic control automatically calculates the optimal speed and feed rate based on the tool diameter and material, producing precise and repeatable results.
The innovative construction with a reinforced radial arm and a Ø 240 mm column ensures rigidity and absence of vibrations. The drilling head is electrically motorized adjustable in height without losing the machining point, suitable for deep drilling and simultaneous machining on multiple workpieces.
The 1200 x 500 mm table allows simultaneous clamping of multiple workpieces, while the quill feed servo motor and continuous speed adjustment (50–2000 rpm) offer maximum operational flexibility. A complete package including a cooling pump, CE protections, LED lighting, and threading devices is included as standard.

Frequently Asked Questions
What does "NC" mean in the name of the SRB radial drilling machine?
NC (Numerical Control) indicates that the machine has numerical control for axis management — it allows programming the spindle position and RPM precisely and repeatedly. SRB NC models can be connected to automation systems for serial drilling on identical workpieces without having to manually reposition the spindle each time.
What is the difference between SRB 40 NC and SRB 50 NC?
The number indicates the maximum drilling capacity in steel: SRB 40 NC (Ø 40 mm), SRB 50 NC (Ø 50 mm). The SRB 50 NC has a longer arm, more powerful motor, and larger table. The choice depends on the maximum diameter of the drills used and the size of the workpieces to be machined.
Is the radial arm motorized?
Yes — in SRB NC models, the movement of the arm and spindle is motorized and controlled by the NC system, unlike manual RD radial drills where the arm is moved manually. This allows for the repeatability of positioning necessary for serial drilling.
Are spare parts available?
