Key construction feature: the digital display for the spindle stroke shows the drilling depth during operation, a crucial feature for applications requiring non-through holes of predefined depth (e.g., blind holes for threads, bearing seats, holes for couplings). The 16 step speeds from 220-2,840 rpm allow adaptation to standard materials: hard steels 220-500 rpm for Ø 15-20 mm, mild steels 1,000-1,500 rpm, aluminum and brass 1,500-2,840 rpm. The IP 54 compliant aluminum motor (0.75 kW S1 \/ 1.1 kW S6) at 230V provides the necessary power for continuous use. The ±45° tiltable table with diagonal T-slots allows for angled drilling without the need for a precision vise. Typical fields of use: artisanal workshops, repair and maintenance of mechanical components, educational laboratories for technical schools, advanced modeling and prototyping, metal hobbyists with higher precision requirements.\u003c\/p\u003e\n\u003ch3\u003eIts place in the Bernardo range\u003c\/h3\u003e\u003cp\u003eThe Bernardo bench and pillar drill range is organized into 6 main sub-families: \u003cstrong\u003eTB\u003c\/strong\u003e (TB 14\/16\/20 T) entry level with fixed B16 or MT 2 taper and step speeds; \u003cstrong\u003eBM T\u003c\/strong\u003e (BM 20\/25 T) intermediate with digital spindle stroke display and step speeds; \u003cstrong\u003eBM Vario\u003c\/strong\u003e (BM 16\/20 Vario) intermediate with continuously variable speed + centering laser; \u003cstrong\u003eSBM Vario\u003c\/strong\u003e (SBM 16\/20 Vario) pillar drill with higher height than BM Vario; \u003cstrong\u003eB 430 Vario\u003c\/strong\u003e medium-heavy pillar drill with 360° swiveling table and MT 3 spindle; \u003cstrong\u003eSB 30 Profi\u003c\/strong\u003e heavy pillar drill with 2-stage power motor, Ø 32 mm capacity. The BM 25 T \/ 230 V is the BM model with step speeds (16 steps from 220-2,840 rpm) and digital display for the spindle stroke. Compared to the corresponding TB: the BM has a digital stroke display, a superior S1 motor, and a B18 chuck (vs B16 for TB). Compared to the BM Vario: the BM T has step speeds (belt changes for new speed) vs continuous for the Vario, does not have a centering laser, and is economically preferable for use without frequent speed adjustment requirements. For drilling up to Ø 25 mm: the BM 25 T is correctly sized with a 0.75 kW motor and 305×305 mm table superior to the BM 20 T.\u003c\/p\u003e\n\u003ch3\u003eLogistics and Krollit support\u003c\/h3\u003e\u003cp\u003eBernardo shipping in 5-9 working days (7 days to the South).

BM bench drills with 0.03-0.05 mm concentricity are suitable for most professional applications. For precision applications (reaming for H7 couplings, precision bearing holes), gear-driven drills are recommended.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\u003csummary\u003eWhat electrical power supply is needed?\u003c\/summary\u003e\n\u003cp\u003e230V voltage: 230V Schuko household\/workshop line without three-phase line, standard 16A circuit breaker. Standard cable cross-section 1.5 mm² up to 30 meters.\u003c\/p\u003e\n\u003cp\u003eFor workshops with a household line (230V), the 230V model is the correct choice without additional electrical adaptation costs. For workshops with a three-phase line (400V), the 400V model is sized with a higher quality motor and extended lifespan: the three-phase motor has higher efficiency (90% vs 70% for single-phase) with less heat generated and significantly longer lifespan (15-25 years vs 8-15 years for single-phase). For intensive continuous use, the 400V model is preferable.\u003c\/p\u003e\n\u003c\/details\u003e","brand":"Bernardo","offers":[{"title":"Default Title","offer_id":50696598913352,"sku":"01-1119","price":658.82,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0891\/2139\/0920\/files\/Trapano_da_banco_Bernardo_BM_25_T_con_display_digitale_e_luce_LED.jpg?v=1757346585","url":"https:\/\/www.krollit.com\/products\/bernardo-bench-drill-bm25t-230v","provider":"Krollit","version":"1.0","type":"link"}
