Who uses the DH 410 S and for what
The Bernardo DH 410 S is the dedicated 410 mm thicknesser with a TCT spiral cutterblock: the choice for joineries with a separate planer that work with doors, panels, and wide beams in continuous cycles and want to eliminate blade maintenance. The 72 TCT inserts on the Ø 95 mm cutterblock offer the same cutting quality as the AD 410 S but in a machine optimized exclusively for thicknessing, with a longer bed including extensions and integrated rollers compared to combination machines. In Krollit customers' workshops, it is used by carpenters and cabinet makers with high-volume thicknessing needs who have already separated the two functions into dedicated machines.
DH 410 S vs AD 410 S: dedicated thicknesser vs. combination machine
Both machines feature the Ø 95 mm cutterblock with 72 TCT inserts. The DH 410 S is optimized for thicknessing only: bed with extensions and integrated rollers for long workpieces, and a more compact structure (239 kg vs 340 kg for the AD 410 S). The AD 410 S additionally has a jointer function but weighs 100 kg more. For those who already have a separate planer, the DH 410 S is lighter and more optimized; for those who do not have a planer, the AD 410 S is more versatile.

Who is the Bernardo DH 410 S – 400V for?
| Profile |
Compatibility |
Reason |
| Passionate hobbyist |
Not recommended |
Dedicated professional thicknesser (239 kg, three-phase). For hobby use, consider combined jointer+thicknesser machines. |
| Joinery with separate planer |
Recommended |
410 mm with 72 TCT inserts, bed with rollers and digital indicator: optimal for continuous thicknessing cycles on wide workpieces with minimal maintenance. |
| Continuous / industrial production |
Recommended |
For high volumes at 410 mm, TCT almost completely eliminates downtime for blade maintenance. |
Not suitable for: workshops without a separate planer; workshops without three-phase 400V; workpieces wider than 410 mm; those who also need a jointer function.

Frequently Asked Questions
Does the DH 410 S also have a jointer function?
No. The DH 410 S is exclusively a thicknesser. It does not have an outfeed table or fence for jointing. For a combined jointer+thicknesser function at 410 mm, the AD 410 S (same TCT cutterblock, same format) is the alternative with both functions.
What is the difference between DH 410 S (TCT) and DH 410 (HSS)?
The DH 410 S features 72 TCT inserts on the Ø 95 mm cutterblock; the DH 410 features 4 HSS knives on the same cutterblock. The structure, dimensions, and motor are identical. TCT offers approximately 50% reduced noise and 10-20 times longer blade life. The DH 410 S has a higher cost but recoups it in saved maintenance within 12-18 months of professional use.
How often are the 72 TCT inserts rotated?
In professional use (6-8 hours/day) on medium woods, one rotation per insert is needed every 6-10 weeks. With 72 inserts, rotation is progressive and distributed over time, they never all stop at once. Replacement inserts are available from Krollit's warehouse with 3-5 business day shipping.
How much space is needed in the workshop?
The machine footprint is 1,110 × 710 × 1,020 mm. For feeding and exiting workpieces up to 410 mm wide, a clear space of at least 2.5 m in front and behind is needed. With 239 kg Bernardo shipping.
What dust extractor is needed for the DH 410 S?
The dust extraction port is Ø 100 mm. For a 410 mm width, a dust extractor with a minimum airflow of 800-1,000 m³/h is recommended. The Bernardo DC 600 (400V) is the recommended solution for continuous professional use at this width.
