Geared drills (GB series) deliver higher torque at low speeds — necessary for deep boring, large diameter tapping, and drilling hard materials over Ø 30 mm. For standard drilling up to Ø 25 mm, belt drive is the correct choice.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eUp to what diameter can the Bernardo BM 25 SB drill in steel?\u003c\/summary\u003e\n\u003cp\u003eNominal capacity Ø 25 mm in S235 steel with HSS drill bit. In AISI 304 stainless steel, capacity is reduced by 30–40% — use specific drill bits for stainless steel and reduced speed with coolant. In aluminum, capacity increases by 30%. For holes over Ø 20 mm in steel, always use the lowest available speed and controlled manual feed.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow to choose the correct speed for the material?\u003c\/summary\u003e\n\u003cp\u003eOptimal 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.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003e400 V power supply: is a special system required?\u003c\/summary\u003e\n\u003cp\u003e400 V three-phase — requires an industrial electrical system.
