Who uses the ADH 250 P and for what purpose
The Bernardo ADH 250 P – 400V is the most compact and lightweight combined jointer-thicknesser in Bernardo's professional range with a 250 mm width in its three-phase version. At 148 kg, it is 25 kg lighter than the AD 260 – 400V (173 kg) and significantly more compact (dimensions 1,100 × 750 mm vs 1,150 × 800 mm). The 1.5 kW motor places it in the entry-level segment: suitable for workshops with limited planing needs, where the 250 mm width and low weight are the main selection criteria. In Krollit customers' workshops, it is primarily used as a first machine by carpenters starting their business, or as a support planer in workshops already equipped with a main machine.
Its place in the Bernardo range
The ADH 250 P occupies the lowest end of Bernardo's three-phase combined planer range at 250 mm: 1.5 kW motor vs 2.0 kW for the AD 260 – 400V, jointing depth up to 5 mm (vs 3 mm for the AD 260), thicknessing height up to 185 mm (vs similar 185 mm). The main difference from the AD 260 is the smaller motor: sufficient for intermittent use and soft-medium woods, more limiting for intensive cycles on hardwoods. For those who can invest slightly more, the AD 260 – 400V offers a more appropriately sized motor for daily professional use.

Who is the Bernardo ADH 250 P – 400V for
| Profile |
Compatibility |
Reason |
| Passionate hobbyist |
Not recommended |
Requires a 400V three-phase system not available in home workshops. For hobby use in single-phase, consider the ADM 260 – 230V. |
| Small joinery / craftsman (1-5 employees) |
Adequate |
For workshops with limited planing needs (2-4 hours/day) on soft and medium woods. The 1.5 kW motor is sufficient for non-intensive use at 250 mm. |
| Continuous / industrial production |
Not recommended |
The 1.5 kW S1 motor is not sized for industrial cycles on hardwoods. Consider the AD 260 – 400V (2.0 kW) or ADM 300 – 400V (3.0 kW). |
Not recommended for: workshops without a 400V three-phase system (choose ADM 260 – 230V); pieces over 250 mm wide or over 185 mm high for thicknessing; intensive production on hardwoods for more than 3 hours/day.

Frequently asked questions
What is the difference between ADH 250 P and AD 260 – 400V?
The ADH 250 P has a 1.5 kW S1 motor (vs 2.0 kW for the AD 260), weighs 148 kg (vs 173 kg), has a slightly more compact footprint, and a jointing depth of up to 5 mm (vs 3 mm for the AD 260). The AD 260 has a faster feed rate (same 4.8 m/min) but a more powerful motor for more intensive daily professional use. For intermittent use, the ADH 250 P is sufficient; for joinery workshops with 4-8 hour shifts, the AD 260 – 400V is the more suitable choice.
Is the 1.5 kW motor sufficient for professional work?
It depends on the intensity of use and the type of wood. For softwoods (pine, fir, poplar) with passes of 1-2 mm, the 1.5 kW motor is sufficient for continuous cycles of 3-4 hours. For hardwoods (oak, ash), it is recommended to reduce the depth of cut to 0.5-1 mm and take breaks every 30-45 minutes to prevent motor overheating. For daily professional use on hardwoods, the AD 260 – 400V with a 2.0 kW motor is preferable.
How do you switch from jointer to thicknesser?
The alignment tables pivot on hinges to expose the thicknesser bed. The two supplied handles facilitate manual flipping of the tables. The operation takes about 30-60 seconds without tools. The Ø 100 mm dust extraction port remains accessible in both working modes.
Can I use the ADH 250 P to plane particle board or MDF?
Not recommended for frequent use. Particle board and MDF contain resins and abrasives that wear HSS knives much faster than solid wood. On these materials, the sharpening frequency can increase by 50-100%. For those who primarily work with panels, consider versions with a helical cutter block and TCT inserts available in other machines in the Bernardo range.
How much space is needed to install the ADH 250 P?
The machine footprint is 1,100 × 750 × 1,010 mm, among the most compact in Bernardo's professional combined planer range. For moving workpieces, a clear space of at least 1.8 m in front and behind is needed. At 148 kg, it can be moved with a manual pallet jack. Delivery is on a standard pallet, no special lifting equipment required.
