Who uses the DH 310 S and for what
The Bernardo DH 310 S is a dedicated thicknesser (not a combination machine): the choice when you already have a separate jointer and are looking for a machine optimized exclusively for thickness reduction. Compared to combination jointer-thicknessers, dedicated thicknessers have more robust feeding mechanisms, tables with integrated extensions and rollers, and structures optimized for continuous thicknessing cycles. The DH 310 S adds the TCT spiral cutterblock with 52 inserts, the same as the AD 310 S, with up to 50% noise reduction and maintenance by rotating the inserts. The digital height indicator is included as standard. In Krollit customers' workshops, it is used by joineries that already have a jointer and are looking for a thicknesser of higher quality than versions with HSS knives.
Dedicated vs. combination thicknesser: when to choose the DH 310 S
A dedicated thicknesser optimizes this function exclusively: longer table (930 mm with extensions and rollers) for long workpieces, more robust feeding mechanism for continuous cycles, structure sized for a single function. It makes sense when you already have a separate jointer and process a high volume of thicknessing that requires a dedicated machine. For those who do not yet have a jointer, a combination jointer-thicknesser like the AD 310 S is more versatile as a first investment.

Who is the Bernardo DH 310 S – 400V for?
| Profile |
Compatibility |
Reason |
| Passionate hobbyist |
Not recommended |
Professional dedicated thicknesser (180 kg, three-phase). For hobby use, consider more versatile combination jointer-thicknessers. |
| Small joinery with separate jointer |
Recommended |
310 mm with TCT cutterblock, digital indicator, and table with extensions and rollers: the dedicated thicknesser for those who already have a jointer and want to optimize the thicknessing phase. |
| Continuous / industrial production |
Recommended |
For intensive thicknessing cycles, the dedicated machine offers a more robust feed and minimal TCT maintenance compared to combination machines. |
Not recommended for: workshops without a separate jointer (consider a combination jointer-thicknesser); workshops without 400V three-phase power; workpieces wider than 310 mm; those who also need a jointer function.

Frequently Asked Questions
Does the DH 310 S also have a jointer function?
No. The Bernardo DH 310 S is exclusively a thicknesser; it does not have an alignment table or fence, so it cannot be used for jointing. For the combined jointer+thicknesser function, the AD 310 S (same width, same TCT cutterblock with 52 inserts) is the alternative with both functions.
What is the difference between DH 310 S and AD 310 S?
The DH 310 S is a thicknesser only; the AD 310 S is a combination jointer-thicknesser. Both use the same Ø 95 mm cutterblock with 52 TCT inserts. The DH 310 S has a longer thicknessing table with integrated extensions and rollers (930 mm total) optimized for continuous thicknessing cycles. The AD 310 S has the alignment table for the jointer function in addition. For those who already have a separate jointer, the DH 310 S is the optimized choice for the thicknessing phase; for those who do not have a jointer, the AD 310 S is more versatile.
What is the advantage of the integrated rollers on the table?
The rollers integrated into the table extensions facilitate the movement of long workpieces during feeding and exiting, reducing operator effort and the risk of the workpiece jamming or tilting during passage. In dedicated thicknessers, rollers are standard because the machine works exclusively with workpieces in automatic feed, often long and heavy.
How often are the 52 TCT inserts rotated?
In professional use (6-8 hours/day) on medium woods, one rotation is necessary every 6-10 weeks per insert. With 52 inserts, rotation is progressive: they do not all stop at once. Replacement TCT inserts are available from Krollit stock with 3-5 working days shipping.
How much space is needed in the workshop?
The machine footprint is 1,110 × 600 × 1,020 mm. For feeding and exiting workpieces, a clear space of at least 2 m in front and behind is needed. With 180 kg Bernardo shipping.
