Who uses the ADM 300 and for what
The Bernardo ADM 300 is a professional combination planer/thicknesser for carpentry shops with a need for extended work cycles. Two features distinguish it from the AD 310 in the same width range: the helical feed roller, which provides a more uniform and secure workpiece feed during thicknessing, and the ground cast iron tables with sound-absorbing lips, which reduce vibrations transmitted to the finished surface and the overall noise level. The 5,500 rpm cutter block (vs 4,300 on the AD 310) produces a higher number of cuts per meter of workpiece fed, with a direct effect on surface quality. In Krollit customers' workshops, it is primarily used by furniture makers and window/door manufacturers for daily 6-8 hour shifts on solid wood.
Its place in the Bernardo range
The ADM 300 occupies the professional-plus segment compared to the AD 310: same approximate width (305 vs 310 mm), but a construction more oriented towards intensive use. The ADM 300 V version adds variable feed from 1 to 10 m/min with a digital display, useful for those who need to adjust the speed based on the type of wood and depth of cut. For those who do not need variable feed, the standard ADM 300 is sufficient and more economical.

Who is the Bernardo ADM 300 β 400V for
| Profile |
Compatibility |
Reason |
| Passionate hobbyist |
Not recommended |
Machine designed for intensive professional use (280 kg, three-phase 400V). For hobbyists with needs up to 250 mm, consider the ADM 260 β 230V. |
| Small carpentry / artisan (1-5 employees) |
Recommended |
The helical roller and sound-absorbing tables make a difference in prolonged daily use. The 5,500 rpm cutter block speed offers superior surface quality compared to entry-level professional planers. |
| Continuous / industrial production |
Recommended |
Designed for intensive work cycles. The integrated trolley facilitates repositioning. For production with widths over 305 mm, consider the ADM 300 in the 410 mm version. |
Not recommended for: hobbyists with occasional use (oversized cost and dimensions); workshops without a three-phase 400V system; processing workpieces over 305 mm wide (consider AD 410 or 410 mm versions).

Frequently Asked Questions
What is the difference between ADM 300 and AD 310?
The ADM 300 has a 5,500 rpm cutter block (vs 4,300 on the AD 310), a helical feed roller for more uniform feeding, ground cast iron tables with sound-absorbing lips, and an integrated trolley. The AD 310 has a slightly larger width (310 vs 305 mm) and weighs 295 vs 280 kg. For intensive professional use (6-8 hour shifts), the ADM 300 is the superior choice for surface quality and operational comfort; for less intensive use, the AD 310 is more economical.
Does the helical feed roller really make a difference?
Yes, especially on workpieces with irregular grain or woods that tend to chip out. The helical (spiral) roller applies progressive and uniform pressure to the workpiece instead of point pressure: it reduces the risk of workpiece lift, improves the consistency of the final thickness along the entire workpiece, and minimizes roller marks on the surface of soft woods. On workpieces with knots or oblique grain, the difference in surface quality is noticeable compared to standard straight rollers.
What is the difference between ADM 300 and ADM 300 V?
The ADM 300 V adds variable feed from 1 to 10 m/min adjustable via a digital display, compared to the fixed feed of 6.6 m/min on the standard ADM 300. Variable feed is useful for adapting the speed to the type of wood (slower on hard woods for a better finish, faster on soft woods for roughing) and for optimizing productivity based on the depth of cut.
How often should the knives be replaced?
In intensive professional use (6-8 hours/day), the 4 HSS 18% knives require sharpening every 2-3 weeks on medium woods, every 1-2 weeks on hard woods. The high cutter block speed (5,500 rpm) produces more cuts per meter advanced, increasing quality but also blade wear. Knives are available as original Bernardo spare parts from Krollit stock with 3-5 business day shipping.
How much space is needed for the ADM 300 in the workshop?
The machine footprint is 1,700 Γ 790 Γ 1,080 mm. For moving workpieces, a clear space of at least 2.5 m in front and behind is needed. The integrated trolley allows internal movement on a level floor without additional equipment. Delivery is on a pallet: weight 280 kg.
