Bernardo Pillar Drilling Machine GB 40 SN Vario with Tilting Table – Power and Precision for Professional Workshops
The Bernardo GB 40 SN Vario pillar drilling machine is a versatile and precise machine, suitable for drilling, reaming, and tapping up to M24. Thanks to the continuous speed adjustment, displayed on the digital screen, it allows easy setting of the optimal cutting speed based on the material and tool used.
The machine is equipped with 2 electromagnetically adjustable automatic spindle feeds, a tapping device, and automatic tool release included as standard. The table rotates around the column and tilts ±45°, increasing flexibility in machining, while the professional-grade base with T-slots allows secure clamping of even very long workpieces.
With hardened and ground gears, guaranteed concentricity ≤0.02 mm, and a 2.2 kW (3.0 kW S6) motor, the GB 40 SN Vario offers reliable and long-lasting performance, suitable for industrial and professional applications.

Frequently Asked Questions
Gear-driven vs. belt-driven drill presses: why choose the GB 40 SN Vario?
The GB 40 SN Vario uses gear transmission: higher torque at low speeds compared to belt-driven drills of the same power — essential for deep reaming, tapping up to M24, drilling cast iron and hard steels, and counterboring operations. The Vario adds continuous speed adjustment without stopping the machine — switching from roughing to finishing in 2 seconds.
What is the maximum drilling diameter in steel with the GB 40 SN Vario?
Nominal capacity Ø 40 mm in S235 steel with HSS drill bit. For large diameter holes (over Ø 25 mm), always use the lowest speed, slow feed, and coolant — heat is the main enemy of the cutting edge. For AISI 304 stainless steel, reduce the capacity by 30–40%. For core drilling, consult Krollit for specific capacity. Customer support available in Italian.
How do the automatic feeds work?
The automatic feeds of the GB 40 SN Vario motorize the spindle's descent at a constant and programmable speed — essential for serial drilling of identical parts (repeatable depth) and for reaming where feed consistency affects hole finish. Select the mm/revolution value from the table and engage the lever.
Is the tilting table genuinely useful?
Yes — the table of the GB 40 SN Vario tilts up to ±45° and rotates 360°: it allows angled drilling on workpieces that cannot be manually tilted, such as large flanges or parts with complex geometries. For standard 90° drilling, the table remains in a vertical position.
Are spare parts available?
Original spare parts available with 3–5 working days shipping. Customer support available in Italian.
