Who uses the Profi 300 V and for what
The Bernardo Profi 300 V is a compact bench lathe from the Profi range (professional entry-level), designed for advanced hobbyists, model makers, and small workshops. Features of the Profi 300 V: distance between centers 300 mm, weight 60 kg, dimensions 740 × 390 × 370 mm. The most compact model in the Profi range: sized for small parts (turning short shafts, fittings, precision parts, advanced model making). DK11 Ø 100 mm 3-jaw chuck with a Ø 20 mm through bore MK3 taper: standard for professional use with interchangeable tools and accessories (MK3 collets, reducers). Continuous electronic variable speed 50-1250/100-2500 rpm in two ranges: low range for torque on hard materials, high range for rapid finishing. Automatic feeds 3 steps (0.083-0.159 mm/rev in the 300 V, 0.089-0.198 in the 400 G/400 V) for finish control. Metric threads 14-15 steps (0.3-3 mm) and inch threads 10-12 steps (10-44 TPI): standard coverage for common threaded part production. Digital speed indicator for precise control of the set rpm. In Krollit customer workshops, compact Profi lathes are chosen by advanced hobbyists who want professional features (threading, feeds, display) in compact bench machines without the need for a dedicated stand.
Its place in the Bernardo range
The Bernardo Profi metal lathe range is organized by progressive size and features: Profi 300 V, 400 G, 400 V (compact 60-65 kg, 0.50-0.60 kW motor, electronic variable speed) for advanced hobbyists and small workshops; Profi 450 S and 450 S Vario (medium 112 kg, 0.90 kW motor) for artisan workshops with daily use; Profi 550 WQ and 550 WQV (heavy 120 kg, 0.75 kW motor but with separate longitudinal+cross feeds and full threading) for professional production of complex threaded parts. Below the Profi range is the Hobby range (entry-level 14-130 kg); above it is the Goliath range (heavy industrial 1,500-3,500 kg).
The Profi 300 V is the professional entry-level model of the Profi range: professional features (full threading, automatic feeds, digital speed display) in a compact bench machine. For continuous professional use with larger parts, the Profi 450 S/450 S Vario (112 kg) or 550 WQ/WQV (120 kg) are correctly sized. For heavy industrial production, the Goliath range is correctly sized. The 3 compact models (300 V, 400 G, 400 V) differ in: 300 V being more compact and slightly less powerful, 400 G with a Ø 21 mm spindle bore and 105 mm center height, 400 V with a Ø 20 mm bore and 100 mm center height.

Who is the Profi 300 V for
| Profile |
Compatibility |
Reason |
| Advanced hobbyist / professional model maker |
Recommended |
Compact 60 kg lathe with professional features: full metric+inch threading, automatic feeds, digital speed display. 300 mm distance between centers and Ø 180 mm swing over bed for small-medium parts. |
| Small artisan workshop |
Recommended |
DK11 Ø 100 mm chuck with through bore for using standard accessories (collets, reducers, 4-jaw chucks for special accessories). Continuous electronic variable speed for tuning to different materials. |
| Workshop with regular production and large parts |
Adequate |
For intensive use with parts over Ø 200-210 mm on the bed, the Profi 450 S/Vario (Ø 230 mm) or the 550 WQ/WQV (Ø 250 mm) with a more powerful motor are correctly sized. |
Not suitable for: daily professional use with large parts (over Ø 210 mm on the bed; the Profi 450 S/Vario or 550 WQ/WQV are correctly sized); workshops without a sturdy 230V industrial line (0.50-0.60 kW motor requires a sized domestic meter); three-phase 400V power supply (for workshops with a three-phase line, the 400V version of the Hobby 500 or Goliath range is correctly sized); programmed CNC (Profi lathes are manual lathes, not CNC).

Frequently Asked Questions
What is the difference between the Profi 300 V and the Hobby models in the range?
Profi compacts are a level above Hobby: professional features (full metric+inch threading, DK11 Ø 100 mm chuck, digital speed display, 0.50-0.60 kW motor) in a compact bench machine. Hobby models are entry-level with simpler features (optional threading on basic models, smaller chuck diameters, 0.15-0.55 kW motors).
Practical difference: for occasional hobby use, a Hobby 250/350 is sufficient; for more intensive use with professional threading requirements, the Profi compact is correctly sized. The Profi medium (450 S/Vario) and heavy (550 WQ/WQV) range is sized for daily professional or continuous advanced hobby use.
Is the 230V single-phase power supply really sufficient for professional use?
For the Profi 300 V, yes. The 0.5 kW (S1) - 0.7 kW (S6) motor is sized for continuous use at 230V single-phase. The machine is designed for professional use in an artisan workshop, not for heavy industrial production.
Recommended check before installation: electrical line with adequate cross-section (4 mm² cable for 0.90+ kW motor, 2.5 mm² for 0.50-0.80 kW motors), dedicated 16-20A circuit breaker, CEE 16A 230V industrial socket. For workshops with other simultaneous loads (compressors, extractors), check the available power on the meter (minimum 6 kW for simultaneous use). For heavy industrial use, the Goliath range with a 9 kW three-phase 400V motor is correctly sized.
What parts can I work with the Profi 300 V?
Typical parts: cylindrical turning of shafts and cylinders up to Ø 180 mm and 300 mm length between centers, facing, grooving, chamfering and radiusing, metric threads (14) 0.3-3 mm and inch threads (10) 10-44 TPI. Typical materials: mild steels (Fe360, S235), alloy steels (C45, 39NiCrMo3), stainless steels (AISI 304, 316), aluminum and light alloys, brass, bronze, technical plastics.
Limitations: maximum Ø over bed 180 mm, spindle bore Ø 20 mm (maximum limit for through bars). For larger parts, the higher models in the Profi range or the Goliath range are correctly sized. For standard occasional hobby use, all Profi models are adequate; for regular production with specific parts, check the capacity of the chosen model.
Can I install the Profi 300 V on any workbench?
Yes, on robust workbenches with a load capacity greater than the machine's weight (60 kg) plus the workpieces. The workbench must be stable and level: instability causes vibrations that compromise work precision.
For artisan workshops, a professional workbench (e.g., Bernardo's WB 2100 Profi) with a solid beech wood top, or a dedicated steel sheet base is recommended. The machine must be fastened to the workbench with through bolts in the designated base holes to prevent sliding during operation.
Is the machine already complete or do I need additional accessories?
The machine comes with standard equipment sufficient for immediate use: DK11 Ø 100 mm 3-jaw self-centering chuck, four-way tool post, fixed tailstock, spare steel gears, spindle guard, chip tray, spare wheels. User manual in Italian.
Optional accessories typically purchased separately: self-centering chucks of different diameters, steady rests for long parts, 4-jaw chuck for non-cylindrical parts, additional turning tool sets (HSS, carbide), collets for MK3/MT4 spindle. For most standard machining, the basic equipment is sufficient; for specific production, evaluate dedicated accessories. All original Bernardo accessories are available from Krollit with 3-5 business days shipping.
