Frequently Asked Questions
Belt-driven vs. gear-driven pillar drill: which to choose?
V-belt drills (like the Bernardo BM 32 SB) are quieter, less expensive, and have sufficient torque for drilling up to Ø 32 mm in standard steel. Gear-driven drills (GB series) provide 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, a belt drive is the correct choice.
What is the maximum drilling diameter on steel with the Bernardo BM 32 SB?
Nominal capacity Ø 32 mm on S235 steel with HSS drill bits. On AISI 304 stainless steel, capacity is reduced by 30–40% — use specific bits for stainless steel and reduced speed with coolant. On aluminum, capacity increases by 30%. For holes over Ø 20 mm in steel, always use the lowest available speed and controlled manual feed.
How to 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 on 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 day shipping. Customer support in Italian available.
