Bernardo Pillar Drill GB 45 NC Vario – Touchscreen Control and Automatic Feeds
The Bernardo GB 45 NC Vario pillar drill combines power, precision, and advanced technology, making it suitable for mechanical workshops and professional carpentry. The continuous speed adjustment is easily readable on the digital display, while the large touchscreen allows you to manage all operating settings.
The machine features 4 automatic spindle feeds via electromagnetic clutch, an integrated threading device, and automatic tool release. The solid cast iron work table (540 x 435 mm) can be tilted by 45° and rotated around the column, while the base with an integrated cooling pump ensures safe and continuous machining. With a spindle concentricity of ≤0.02 mm, hardened and ground gears in an oil bath, and a 2.0 kW motor, the GB 45 NC Vario ensures high performance even in intensive use.

Frequently Asked Questions
What is the NC touchscreen system and how does it change the work compared to a standard drill?
The NC system of the GB 45 NC Vario automatically calculates the optimal speed by entering the tool diameter and material — eliminating manual searching in the speed chart. The touchscreen sets speed, depth, and feed in seconds instead of the minutes required for belt changes or manual adjustment. The electromagnetic axis lock maintains the programmed position between holes. For series production of identical parts, repeatability is a concrete advantage compared to manually adjusted drills.
What is the maximum drilling diameter in steel and the maximum threading size with the GB 45 NC Vario?
Nominal drilling: Ø 45 mm in S235 steel. Threading: up to M36. The capacity in AISI 304 stainless steel is reduced by 30–40%. For large diameter drilling (over Ø 35 mm), use the minimum available speed with automatic feed and abundant coolant.
What exactly does the electromagnetic engagement of the automatic feeds allow?
With electromagnetic engagement, the automatic feed is activated and deactivated via the touchscreen without touching physical mechanisms. For a series of identical holes: set the depth once, activate the engagement for the first hole, and the machine reaches the depth and rises automatically. Typical cycle per hole: 3–5 seconds compared to 15–20 seconds for manual feed. For 100 identical holes, a saving of 15–25 minutes.
Is the drilling table inclinable?
Yes — the table of the GB 45 NC Vario is hand-scraped cast iron and inclinable from -45° to +45°, with motorized elevation via a button. Motorized elevation eliminates the need to unscrew and manually crank the toothed column — on heavy machines like this one (over 500 kg), it's a concrete advantage in terms of time and effort.
Are spare parts available?
Original spare parts available with 3–5 working day shipping. Customer support in Italian available.
