Who uses the B 430 Vario / 400 V and for what
The Bernardo B 430 Vario / 400 V is a medium-heavy duty pillar drill with precision characteristics superior to SBM and BM models. Key design feature: the cast iron structure with a Ø 80 mm polished steel column offers superior rigidity to SBM drills (Ø 72 mm), allowing precision drilling on heavy workpieces without vibrations. The 345 × 345 mm cast iron table with cooling grooves can swivel 360° around the column: this flexibility allows optimal workpiece positioning for machining, a feature absent in BM/SBM models with only ±45° tilting tables. Continuously adjustable speed from 280 to 2,600 rpm: suitable range for mild steels (1,000-2,000 rpm) and hard materials at low speed (280-500 rpm) that require maximum torque. The MT 3 taper supports tools up to Ø 25 mm, 3-16 mm keyless chuck with B16 shank. Spindle-to-base distance 1,250 mm and spindle-to-table distance 790 mm: the B 430 Vario is sized for professional workshops with industrial parts of significant height. Typical areas of use: professional mechanical workshops, metal fabricators for welded structures, heavy prototype workshops, professional technical schools.
Its place in the Bernardo range
The Bernardo bench and pillar drill range is organized into 6 main sub-families: TB (TB 14/16/20 T) entry level with fixed B16 or MT 2 taper and step speeds; BM T (BM 20/25 T) intermediate with digital spindle stroke display and step speeds; BM Vario (BM 16/20 Vario) intermediate with continuously adjustable speed + centering laser; SBM Vario (SBM 16/20 Vario) pillar drill with greater height than BM Vario; B 430 Vario medium-heavy duty pillar drill with 360° swiveling table and MT 3 spindle; SB 30 Profi heavy-duty pillar drill with 2-stage power motor, Ø 32 mm capacity. The B 430 Vario is the distinctive model of the medium-heavy duty pillar range: 360° swiveling table around the column (a feature absent in SBM models with only ±45° tilting tables), Ø 80 mm column (vs 72 mm of SBM), Ø 25 mm capacity with MT 3 taper (vs Ø 16-20 mm with MT 2 of SBM). For professional workshops requiring flexible workpiece positioning and Ø 25 mm capacity, the B 430 is the correct choice. For higher capacities (Ø 32 mm), the SB 30 Profi with a 2-stage motor and heavier structure is correctly sized.

Frequently Asked Questions
How does the 360° swiveling table work?
The 345 × 345 mm cast iron table can rotate 360° around the vertical column thanks to a rotary joint at the base of the table. The operator loosens a locking lever, rotates the table to the desired position, and tightens the lever. Typical time: 5-15 seconds.
A crucial feature for: angled drilling on cylindrical workpieces (e.g., radial holes on tubes and bars), radial holes on flanges and discs, prototyping operations with non-standard angles (e.g., 30°, 60°, 120° holes), applications requiring access to the workpiece from different angles without re-mounting. For workshops with a variety of operations, the swiveling table significantly increases flexibility of use.
What is the difference between MT 3 and MT 2 taper?
The MT 3 Morse taper is sized for tools with diameters Ø 16-25 mm (drilling, reaming, M threading); the MT 2 taper is for tools Ø 8-16 mm. The B 430 Vario has an MT 3 taper (vs MT 2 of BM/SBM models): it supports larger diameter tools.
For workshops with Ø 16-25 mm tools, the B 430 Vario is the correct choice. For workshops with Ø 8-16 mm tools, BM/SBM models with MT 2 are economically preferable. Reduced taper sleeves (MT 3 → MT 2) allow the use of smaller tools on the B 430 Vario, but with loss of rigidity. HSS drill bits with MT 3 taper are significantly more expensive than MT 2 bits.
Is the 1,250 mm spindle-to-base distance really useful?
Yes, for tall workpieces. The 1,250 mm spindle-to-base distance allows positioning of workpieces up to 1,250 mm high on the base, with the table moved to the working position: a crucial feature for drilling on tall welded structures, bulky frames, long cylindrical workpieces.
For standard workpieces (height under 790 mm), the table is used in the standard position, with a max spindle-to-table distance of 790 mm. For taller workpieces, the table is moved aside or removed, and the workpiece is placed directly on the cast iron base with T-slots. The base with T-slots allows clamping with standardized T-nuts for stability during drilling.
What does the IP 54 motor mean?
IP 54 is a motor protection standard: 5 indicates protection against dust (limited penetration, no damage), 4 indicates protection against water splashes from any direction. The IP 54 motor is sized for workshops with machining dust and occasional coolant splashes.
For workshops with high dust levels (woodworking, metalworking with dusty chips) or frequent coolant splashes, IP 54 protection is a crucial feature for motor longevity. For environments with constant exposure to water or corrosive liquids, IP 65+ motors are required (total protection against dust + protection against water jets). The B 430 Vario is sized for standard workshop use with IP 54 compliance.
For which higher capacities is it necessary to switch to the SB 30 Profi?
For capacities Ø 25-32 mm, the SB 30 Profi is correctly sized with a 2-stage motor (0.55/0.85 kW vs 0.75 kW of the B 430), 120 mm spindle stroke (vs 80 mm), weight 245 kg (vs 100 kg). For continuous heavy industrial applications, the SB is the correct choice.
Economic comparison: the SB 30 Profi costs significantly more than the B 430 Vario, but the difference is justified for workshops with daily use of heavy drilling. For intermittent use of Ø 25 mm, the B 430 Vario is economically preferable. For daily use of Ø 25 mm or drilling Ø 25-32 mm, the SB 30 Profi is correctly sized.
