Bernardo Pillar Drill GB 35 Vario – Precision and versatility with electromechanical feed
The Bernardo GB 35 Vario pillar drill is a compact and robust machine, designed for drilling, reaming, and tapping up to M24. The continuous speed adjustment (65–3250 rpm) ensures optimal adaptation to every material, while the digital display simplifies operational control.
The machine is equipped with an electromechanical spindle feed (0.1 – 0.3 mm/rev), a tapping device, and an automatic tool ejector, all included as standard. The cast iron table, which can be tilted and rotated, offers maximum flexibility, while the base with T-slots allows for clamping oversized workpieces. Hardened and ground gears ensure smooth operation, while a guaranteed concentricity of ≤0.02 mm confirms the reliability of the GB 35 Vario as a tool for workshops and mechanical companies.

Frequently Asked Questions
Gear-driven vs belt-driven drill: why choose the GB 35 Vario?
The GB 35 Vario uses a gear-driven transmission: higher torque at low speeds compared to belt-driven drills of the same power — essential for deep reaming, tapping up to M20, drilling cast iron and hard steels, and counterboring operations. The Vario adds continuous speed adjustment without stopping the machine — allowing you to switch from roughing to finishing in 2 seconds.
What is the maximum drilling diameter on steel with the GB 35 Vario?
Nominal capacity Ø 35 mm on 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. On stainless steel AISI 304, 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 35 Vario motorize the spindle descent at a constant and programmable speed — indispensable for series drilling of identical parts (repeatable depth) and for reaming where feed consistency affects hole finish. Select the mm/rev value from the table and engage the lever.
Is the tilting table actually useful?
The standard table of the GB 35 Vario is fixed but rotates 360° around the column — allowing you to change the working position without moving the heavy workpiece, useful for off-axis workpieces relative to the column.
Are spare parts available?
