Key constructive feature: the TB model is the simplified version of the BM range, with a significantly lower price while maintaining Bernardo's constructive quality. Differences compared to the corresponding BM: no digital display, standard belt drive without additional components, simplified ergonomics. The 16 step speeds of 220-2,840 rpm allow adaptation to standard materials. The IP 54 compliant aluminum motor (0.55 kW S1 \/ 0.80 kW S6) at 400V three-phase develops the necessary power for normal daily use. The 290 × 290 mm cast iron table, inclinable ±45° with T-slots, allows for angled drilling. The right\/left rotation allows for tapping with a tap without the need for manual spindle stops. Typical application areas: metal hobbyists with standard precision requirements, artisan workshops with occasional use, model makers for constructing frames and small mechanisms, basic educational laboratories for technical schools.\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 or MT 2 taper and step speeds; \u003cstrong\u003eBM T\u003c\/strong\u003e (BM 20\/25 T) intermediate with digital spindle travel 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 greater height than BM Vario; \u003cstrong\u003eB 430 Vario\u003c\/strong\u003e medium-heavy duty pillar drill with 360° swiveling table and MT 3 spindle; \u003cstrong\u003eSB 30 Profi\u003c\/strong\u003e heavy-duty pillar drill with 2-stage power motor, Ø 32 mm capacity.

For precision tapping, M over M10, or frequent tapping, mechanical R\/L rotation is a key feature.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails\u003e\u003csummary\u003eIs the TB truly professional or just for hobbyists?\u003c\/summary\u003e\n\u003cp\u003eProfessional entry-level. The TB is manufactured according to the same constructive standards as the BM\/SBM Bernardo range (cast iron frame, IP 54 motor, quality bearings) but with simplified features to reduce the price.\u003c\/p\u003e\n\u003cp\u003eFor artisan workshops with standard daily use, the TB is completely adequate: the hole quality and machine durability are comparable to the corresponding BM. The differences (no digital display, basic ergonomics, step speeds) impact work efficiency but not the technical quality of drilling. For advanced hobbyist use, the TB is the correct choice in terms of quality\/price. For intensive professional use with efficiency requirements, the BM Vario or SBM Vario are correctly sized.\u003c\/p\u003e\n\u003c\/details\u003e","brand":"Bernardo","offers":[{"title":"Default Title","offer_id":50696700395848,"sku":"01-1041","price":594.02,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0891\/2139\/0920\/files\/Trapano_da_banco_Bernardo_TB_20_T_400_V_compatto_e_robusto.jpg?v=1758008381","url":"https:\/\/www.krollit.com\/products\/drills-bench-bernardo-tb-20t-400v","provider":"Krollit","version":"1.0","type":"link"}
