Who uses the PT 310 S and for what
The Bernardo PT 310 S is the version with a TCT spiral cutterblock of the PT 310: same compact structure (180 kg), same workshop format, but with TCT technology that almost completely eliminates cutter maintenance. For those who want 310 mm width in a light format and want to add the advantage of TCT without moving to heavier machines like the AD 310 S (295 kg). The 8 m/min feed rate, higher than the AD 310 S (6 m/min), makes it more productive for roughing softwoods. In Krollit customers' workshops, it is chosen by carpenters who value the combination of lightness + minimal maintenance.
PT 310 S vs AD 310 S: the choice between lightness and mass
Same width (310 mm), same TCT cutterblock, but different structure. The PT 310 S weighs 180 kg and has a 1,300 mm jointer table; the AD 310 S weighs 295 kg with a 1,610 mm table. The mass of the AD 310 S provides more stability on large and heavy pieces; the PT 310 S is more manageable and takes up less space. The thicknessing height is identical (180 mm for the PT 310 S vs 225 mm for the AD 310 S); those who work pieces up to 225 mm high must choose the AD 310 S.

Who is the Bernardo PT 310 S – 400V for
| Profile |
Compatibility |
Reason |
| Passionate hobbyist |
Suitable |
Three-phase 400V required. TCT is also appreciated in hobby use for minimal maintenance. For pure hobby use, consider single-phase versions. |
| Small joinery / artisan (1-5 employees) |
Recommended |
310 mm with TCT in a 180 kg format: the optimal combination for workshops with limited space that want to eliminate sharpening from their routine. |
| Continuous / industrial production |
Suitable |
For intensive cycles on large pieces, consider the AD 310 S (295 kg, more stable) or the ADM 300 with helical roller. The PT 310 S is suitable for shifts up to 6 hours. |
Not suitable for: pieces with thicknessing height over 180 mm (consider AD 310 S with 225 mm); workshops without three-phase 400V; production of very heavy pieces requiring the structural mass of the AD 310 S.

Frequently Asked Questions
What is the difference between PT 310 S and PT 310 (HSS)?
The PT 310 S features a spiral cutterblock with 30 TCT inserts instead of the 3 HSS knives of the standard PT 310. Structure, weight (180 kg), dimensions, and motor (2.2 kW) are identical. TCT offers: approx. 50% noise reduction, 10-20 times longer cutting edge life, maintenance by rotating the insert without disassembly. The cost of the PT 310 S is higher but is recovered in saved maintenance in 12-18 months of professional use.
Does the PT 310 S have the same thicknessing height as the AD 310 S?
No. The PT 310 S has a maximum thicknessing height of 180 mm; the AD 310 S reaches 225 mm. If you work pieces with a height between 180 and 225 mm, the AD 310 S is necessary. For pieces up to 180 mm, the PT 310 S is sufficient and weighs 115 kg less (180 vs 295 kg).
How is maintenance of TCT inserts performed on the PT 310 S?
Each TCT insert has 4 cutting edges. When the surface quality decreases, rotate the insert by 90° with a hex key (2 minutes, no cutterblock disassembly). Complete replacement only occurs when all 4 cutting edges are worn. With 30 inserts, you work on 1-3 at a time, progressively, without ever stopping production for a complete replacement.
Is the 8 m/min feed rate too fast for hardwoods?
For hardwoods (oak, ash) with an 8 m/min feed rate, it is advisable to reduce the depth of cut to 1-1.5 mm to avoid motor overload and fiber tear-out. For softwoods (pine, fir), the full 8 m/min feed rate with 2-3 mm passes is feasible without problems. TCT handles speed variations better than HSS knives on woods with difficult grain.
How much space is needed in the workshop?
The machine footprint is 1,300 × 900 × 1,180 mm. For handling pieces, a clear space of at least 2 m in front and behind is needed. At 180 kg, it can be moved with a hand pallet truck on a flat floor.
