Key design feature: the continuous speed adjustment from 400-1,950 rpm allows precise setting of the optimal speed for each tool and material, unlike step versions that force jumps between predefined speeds. For applications with variable diameter tools (e.g., multiple drillings of different diameters on the same piece) the Vario system avoids changing belt positions on the pulleys: the operator adjusts the speed via a knob without stopping the machine. The integrated digital display shows the set speed and spindle stroke in real-time: a crucial feature for productions with frequent parameter changes. The cross-laser device projects a cross onto the workpiece for quick hole centering: it reduces workpiece positioning time from 30-60 seconds (manual centering with a punch) to 5-10 seconds (laser alignment). Typical areas of use: prototyping workshops, precision laboratories, repair shops with variable drilling cycles, advanced metal hobbyists with higher than standard precision requirements.\u003c\/p\u003e\n\u003ch3\u003eIts place in the Bernardo range\u003c\/h3\u003e\u003cp\u003eThe Bernardo range of bench and pillar drills is organized into 6 main sub-families: \u003cstrong\u003eTB\u003c\/strong\u003e (TB 14\/16\/20 T) entry-level with fixed B16 taper or MT 2 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 adjustable 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 16 Vario \/ 400 V is the BM model with continuously adjustable speed (Vario system) + cross-laser device for hole centering. Compared to the corresponding BM T: the BM Vario has continuous speed adjustment (vs step), centering laser, digital speed and stroke display (vs only stroke for BM T). For workshops with frequent speed adaptation requirements to the material or precision machining, the Vario is the correct choice; for standard use without frequent adjustment requirements, the BM T is economically preferable. For higher heights (workpieces up to 690 mm high), the SBM Vario models are correctly sized with the same Vario feature but a pillar structure.\u003c\/p\u003e\n\u003ch3\u003eKrollit logistics and support\u003c\/h3\u003e\u003cp\u003eBernardo shipping in 5-9 working days (7 days in the South).

work?\u003c\/summary\u003e\n\u003cp\u003eThe Vario adjustment uses variable diameter pulleys (Reeves system) or an electronic variator to change the spindle rotation speed without stopping the

For higher precision applications (concentricity ≤ 0.02 mm), geared drills (GB 30 TV) with hardened and ground transmission are required. For standard applications, the BM Vario is correctly sized.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\u003csummary\u003eAre the 6 digital digits useful?\u003c\/summary\u003e\n\u003cp\u003eYes. The integrated digital display shows 2 values in real-time: spindle speed in rpm (4 digits, range 0400-1950) and spindle stroke in mm (3 digits + decimal 00.0-80.0). The operator monitors both parameters during machining.\u003c\/p\u003e\n\u003cp\u003eFor series production, the digital display allows: verification of the set speed without consulting tables, monitoring depth during blind hole drilling, precise recording of machining parameters for repeatability on subsequent parts. Without a digital display, the operator must consult speed tables and use depth stops for depth: significantly less efficient procedures.\u003c\/p\u003e\n\u003c\/details\u003e","brand":"Bernardo","offers":[{"title":"Default Title","offer_id":50696626962760,"sku":"01-1125","price":667.22,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0891\/2139\/0920\/files\/Trapano_a_colonna_Bernardo_BM_16_Vario_400_V_compatto_e_digitale.jpg?v=1758013403","url":"https:\/\/www.krollit.com\/products\/bernardo-drills-bm-16-vario-400v","provider":"Krollit","version":"1.0","type":"link"}
