Bernardo Bench Drilling Machine GB 30 Vario with Digital Indicator
The Bernardo GB 30 Vario is a geared bench drilling machine with continuous speed adjustment and a digital speed indicator, designed for workshops, maintenance, and production. Thanks to its electromagnetic spindle feed, tapping device, and integrated cooling system, it offers precision, repeatability, and long life even in heavy-duty operations. Drilling capacity reaches up to Ø 32 mm in steel and Ø 35 mm in cast iron, with a max. tapping of M22. The MK3 Morse taper and included accessories (1–13 mm/B16 chuck, reduction sleeves, automatic ejector, LED light, protective cover) make the setup complete and immediately operational, also thanks to the initial filling with Shell Tellus 46. Solid construction, Ø 110 mm column, and weight of 320 kg for stable and safe machining.

Frequently Asked Questions
Geared vs. Belt Drill Press: Why choose the GB 30 Vario?
The GB 30 Vario uses geared transmission: higher torque at low speeds compared to belt drill presses 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 — switching from roughing to finishing in 2 seconds.
What is the maximum drilling diameter in steel with the GB 30 Vario?
Nominal capacity Ø 30 mm in S235 steel with HSS drill bits. 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 capacity by 30–40%. For core drilling, consult Krollit for specific capacity. Customer support available in Italian.
How do automatic feeds work?
The automatic feeds of the GB 30 Vario motorize the spindle descent at a constant and programmable speed — indispensable for series drilling on identical parts (repeatable depth) and for reaming where consistent feed affects hole finish. Select the mm/rev value from the table and engage the lever.
Is the tilting table really useful?
The standard table of the GB 30 Vario is fixed but rotates 360° around the column — allowing you to change the working position without moving heavy parts, useful for parts off-axis from the column.
Are spare parts available?
Original spare parts available with 3–5 working days shipping. Customer support available in Italian.
