Bernardo Pillar Drill SB 32 S / 400 V – Powerful, precise, and reliable
The Bernardo SB 32 S pillar drill is a professional machine designed for drilling up to Ø 32 mm. Thanks to its high-torque aluminum motor, compliant with IP54 standards, and quality bearings, it ensures consistent power, long life, and high spindle concentricity.
The treated work table, inclinable ±45° and height-adjustable via a rack and crank, is equipped with T-slots and a coolant groove, allowing for versatile and safe processing. The cast iron base with T-slots also allows for clamping large workpieces. The SB 32 S drill is also equipped with right/left rotation for tapping, a precision keyless chuck, and a height-adjustable guard with a microswitch.

Frequently Asked Questions
Belt-driven vs. gear-driven pillar drill: which to choose?
Belt-driven drills (like the Bernardo SB 32 S - Pillar Drill) are quieter, less expensive, and have sufficient torque for drilling up to Ø 32 mm in standard steel. Gear-driven drills (GB series) deliver higher torque at low speeds — necessary for deep reaming, large diameter tapping, and drilling hard materials beyond Ø 30 mm. For standard drilling up to Ø 32 mm, belt drive is the correct choice.
What is the maximum drilling diameter in steel with the Bernardo SB 32 S - Pillar Drill?
Nominal capacity Ø 32 mm in S235 steel with an HSS drill bit. In AISI 304 stainless steel, the capacity is reduced by 30–40% — use specific drill bits for stainless steel and reduced speed with coolant. In aluminum, the capacity increases by 30%. For holes over Ø 20 mm in steel, always use the lowest available speed and controlled manual feed.
How do you choose the correct speed for the material?
Optimal peripheral speed: mild steel 15–25 m/min, stainless steel 8–15 m/min, aluminum 60–100 m/min, plastic 40–80 m/min. The formula: n (rpm) = (v × 1000) / (π × d). For Ø 10 mm drill bits in steel: 500–800 rpm. Too high a speed burns the cutting edge; too low causes vibrations and long chips that wrap around the drill bit. The belt drive allows selection of predefined speeds — choose the one closest to the calculated optimal speed.
400 V power supply: is a special system required?
400 V three-phase — requires an industrial electrical system. Check for three-phase power and the capacity of the electrical panel before purchase.
Are spare parts available?
Original spare parts available with 3–5 working days shipping. Customer service available in Italian.
