Bernardo Pillar Drilling Machine GB 40 S Vario – Power and Precision with Automatic Feeds
The Bernardo GB 40 S Vario pillar drilling machine is designed for high performance and versatility in professional drilling and tapping operations up to M24. Thanks to its continuous speed adjustment (55–2000 rpm) and digital display, the operator can easily set the appropriate cutting speed for any material.
The machine features 2 electromagnetically adjustable automatic spindle feeds, an integrated tapping device, and automatic tool ejection. The 360° swiveling and ±45° tiltable table allows for great flexibility, while the base with T-slots ensures secure clamping of even large workpieces. The hardened and ground gears ensure quiet operation and a long service life, while the guaranteed concentricity of ≤0.02 mm ensures consistent precision.

Frequently Asked Questions
Geared vs. belt drill: why choose the GB 40 S Vario?
The GB 40 S Vario uses gear transmission: higher torque at low speeds compared to belt drills of the same power – crucial for deep reaming, tapping up to M24, drilling in cast iron and hard steels, and counterboring operations. The Vario also adds continuous speed adjustment without stopping the machine – you can switch from roughing to finishing in 2 seconds.
What is the maximum drilling diameter in steel with the GB 40 S Vario?
Nominal capacity Ø 40 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 AISI 304 stainless steel, reduce capacity by 30–40%. For core drilling, consult Krollit for specific capacity. Customer support in Italian available.
How do automatic feeds work?
The automatic feeds of the GB 40 S Vario motorize the spindle's descent at a constant and programmable speed – essential for series drilling on identical parts (repeatable depth) and for reaming where constant feed affects the 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 40 S Vario is fixed but rotates 360° around the column – it allows you to change the working position without moving heavy workpieces, useful for workpieces that are off-axis relative to the column.
Are spare parts available?
