Who uses the SB 30 Profi and for what
The Bernardo SB 30 Profi is a heavy-duty pillar drill for professional industrial workshops, with stability and power characteristics significantly superior to the BM/SBM/B 430 models. Key constructive feature: the 2-stage power motor (0.55 / 0.85 kW S1) allows for speed selection with variable torque: low stage 105-300 rpm with maximum torque for Ø 20-32 mm tools on heavy steels, high stage 600-1,725 rpm for Ø 8-16 mm tools on standard steels. Highly stable grey cast iron structure with a weight of 245 kg: significantly superior to SBM (57-68 kg) and B 430 (100 kg) models for stability in heavy drilling. Ø 100 mm column: the most rigid in the Bernardo medium bench/pillar drill range. Drilling capacity Ø 32 mm with MT 3 taper, spindle stroke 120 mm (vs 80 mm for BM/SBM models): allows long drilling operations in a single spindle descent, avoiding multiple passes on deep holes. Right/left spindle rotation for tapping M up to the machine's capacity. Typical application sectors: mechanical industry with heavy part production, metal carpentry for industrial structures, workshops for processing alloy steels and tough materials, industrial part prototyping workshops.
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 pillar drill with 360° swiveling table and MT 3 spindle; SB 30 Profi heavy pillar drill with 2-stage power motor, Ø 32 mm capacity. The SB 30 Profi is the heavy model in the medium column range: Ø 32 mm capacity with MT 3 taper, 2-stage power motor, weight 245 kg (vs 100 kg for the B 430 and 57-68 kg for the SBMs). For professional industrial workshops with heavy drilling requirements on industrial parts, it is the correct choice. For higher capacities, the industrial fixed column KBM models (KBM 25/32/40+) with fixed table and greater positioning precision are correctly sized.
Krollit Logistics and Support
Bernardo shipping in 5-9 working days (7 days to the South). Due to significant weight, a pallet truck or crane is required for unloading from the transport vehicle and installation. HSS drill bits, milling chucks, tapping devices, LED lamps, original Bernardo spare parts (belts, motors, keyless chucks, taper shanks, T-nuts) available from stock with 3-5 working days shipping. Customer support available in Italian.
Who is the SB 30 Profi for?
| Profile |
Compatibility |
Reason |
| Industrial workshops with heavy drilling |
Recommended |
Ø 32 mm capacity with 2-stage motor (0.55/0.85 kW S1), 120 mm spindle stroke for deep holes, 245 kg cast iron structure for stability. |
| Workshop with frequent M threading |
Recommended |
Right/left rotation for tapping, significant tapping capacity with MT 3 taper. |
| Workshop with standard use below Ø 25 mm |
Oversized |
For standard use below Ø 25 mm, the B 430 Vario is economically preferable (weight 100 kg vs 245 kg, significantly lower price). |
Not suitable for: drilling diameters greater than Ø 32 mm (KBM fixed column models required); environments without space for industrial-sized machines (weight 245 kg, dimensions 470 × 810 × 1,710 mm); occasional hobby use (oversized, consider TB or BM).

Frequently Asked Questions
How does the 2-stage power motor work?
The motor has 2 internal electrical windings: low stage (0.55 kW S1, 0.80 kW S6) for maximum torque at low speeds (105-300 rpm) for Ø 25-32 mm tools on heavy steels; high stage (0.85 kW S1, 1.2 kW S6) for higher speeds (600-1,725 rpm) with reduced torque for Ø 8-16 mm tools on standard steels.
The operator selects the stage via a dedicated switch depending on the material and tool. This is a crucial feature for: heavy applications requiring high torque on large tools (the high stage would be insufficient for Ø 32 mm on steel), light applications requiring high speeds (the low stage would be slow for Ø 8 mm on mild steel). Standard single-stage drills require a compromise between torque and speed: the SB 30 Profi eliminates this compromise.
Is the 120 mm spindle stroke significant?
Yes, for deep holes. The 120 mm spindle stroke allows long drilling operations in a single spindle descent (vs 80 mm for BM/SBM models): for deep holes 80-120 mm, multiple passes with spindle repositioning are not necessary.
This is a crucial feature for: through holes on thick parts 80-120 mm (structural steel, metal blocks, welded carpentry parts), holes for standard length pins, holes for long M threads (e.g., M16 × 100 mm). Without sufficient spindle stroke, the operator must perform drilling in multiple passes: stop the machine, return the spindle to the top, reposition the workpiece or extract the tool for chips, restart. This procedure is slow and carries a risk of misalignment.
Is the 245 kg structure really more stable?
Yes, significantly. The weight of 245 kg vs 100 kg for the B 430 and 57-68 kg for the SBMs offers superior mass stability: during drilling, spindle vibrations are absorbed by the machine's mass instead of propagating to the workpiece or operator.
For heavy industrial applications, stability is a crucial feature for: hole quality (vibrations cause non-round holes and degraded tolerances), tool life (vibrations cause alternating stresses on the cutting edge, reducing useful life), operator comfort (vibrations propagate to the control levers). For heavy series production, the SB 30 Profi is correctly sized.
Is the digital speed display accurate?
Yes, with a typical resolution of 1 rpm. The display shows the actual spindle rotation speed measured by an inductive sensor: in case of heavy load, the actual speed may be slightly lower than the set speed (load-induced slowdown effect).
This is a crucial feature for: series production with verification of machining speed, precision applications requiring specific speed to optimize hole quality, operator training (the display shows in real-time how speed varies according to load). Without a digital display, the operator estimates the speed based on the control's position: an approximate estimate with a typical error margin of ±10%.
Does R/L rotation allow standard threading?
Yes. The right/left spindle rotation allows M threading using a tap: clockwise rotation cuts the thread (advancing the tap into the material), counter-clockwise rotation ejects the tap from the hole (returning to the initial position).
For precision threading, the SB 30 Profi with R/L rotation is the correct choice: significant threading capacity with MT 3 taper, 2-stage motor for variable torque on threads of different diameters. Specific oil for steel threading (e.g., CutCool, Tapping Fluid) is recommended for thread quality and tap life. For frequent M16-M20 threads, the SB 30 is correctly sized.
