Key structural feature: the massive cast iron structure (950 kg weight) with adjustable dovetail guides offers stability for precision drilling. The 2.2 kW motor with 160 Nm torque and 9,000 N feed force develops the necessary power for through drilling on mild structural steel, medium alloy steels (C45, 39NiCrMo3), cast iron, aluminum and light alloys. The automatic spindle feed with 9 ranges (0.056-1.8 mm\/rev) allows automated execution of long drills (over 50 mm deep) without operator fatigue. The threading device with automatic reversal allows M16 threading without the need to manually stop the spindle: the motor rotation automatically reverses when the set depth is reached. In Krollit customer workshops, KBM 25 and KBM 32 drilling machines are chosen by mechanical workshops with serial production of medium-sized parts, technical schools and professional training workshops, industrial maintenance workshops for component repairs, and metal structural works for assembly holes on welded structures.\u003c\/p\u003e\n\u003ch3\u003eIts place in the Bernardo range\u003c\/h3\u003e\u003cp\u003eThe Bernardo drilling machine range is organized into 3 main categories: \u003cstrong\u003ebench drills\u003c\/strong\u003e (DMT 20, BM, TB) for craft workshops with occasional use; \u003cstrong\u003efixed column drills\u003c\/strong\u003e (KBM 25\/32\/40\/50\/63\/80) for industrial workshops with high-capacity mechanical production; \u003cstrong\u003egear drills\u003c\/strong\u003e (GB 30 TV) for precision workshops requiring superior concentricity. The KBM 25 and KBM 32 are the most compact models in the KBM range, sharing the frame (550×400 mm table, 950 kg weight) and motor (2.2 kW, 160 Nm torque). Differences: the KBM 25 has max drilling Ø 25 mm with MT 3 taper and M16 threading; the KBM 32 has drilling Ø 32 mm with MT 4 taper and M22 threading. For workshops with prevalent use of tools Ø under 25 mm, the KBM 25 is the correct choice in terms of quality\/price; for workshops with tools up to Ø 32 mm, the KBM 32 is correctly sized with the same structure but a larger taper. For higher capacities (Ø 40 mm), the KBM 40\/50 models (medium category with 3-4 kW motor and 350 Nm torque) are correctly sized.\u003c\/p\u003e\n\u003ch3\u003eKrollit logistics and support\u003c\/h3\u003e\u003cp\u003eBernardo shipping in 5-9 working days (7 days to the South).
