Key design feature: the massive cast iron structure (weight 950 kg) 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 holes (over 50 mm deep) without operator fatigue. The threading device with automatic reversal allows M22 threading without the need for manual spindle stop: the motor rotation automatically reverses when the set depth is reached. In Krollit customer laboratories, KBM 25 and KBM 32 drills are chosen by mechanical workshops with series production of medium-sized parts, technical schools and professional training laboratories, industrial maintenance workshops for component repairs, metal structural workshops for assembly holes on welded structures.\u003c\/p\u003e\n\u003ch3\u003eIts place in the Bernardo range\u003c\/h3\u003e\u003cp\u003eThe Bernardo drill 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 (table 550×400 mm, weight 950 kg) and motor (2.2 kW, 160 Nm torque). Differences: the KBM 25 has a max drilling capacity of Ø 25 mm with MT 3 taper and M16 threading; the KBM 32 has a drilling capacity of Ø 32 mm with MT 4 taper and M22 threading. For workshops primarily using tools below Ø 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).
