Sander vs. Thickness Planer: When to Use Which
A sander evens out the thickness of panels and already planed pieces using rotating abrasive belts. Unlike a thickness planer which removes material with blades, a sander works by abrasion, eliminating variations of 0.1-0.5mm and preparing the surface for varnishing or gluing.
Use a sander when: you need to even out multi-layer panels, eliminate planing marks, prepare surfaces for finishing, or work with difficult grain wood that would cause tear-out with a planer.
Use a planer when: you need to remove more than 2mm of material, quickly reduce rough thickness, or create flat surfaces from unworked wood.
Many woodworking shops use both: a jointer/planer for roughing, and a sander for finishing.

Frequently Asked Questions
How many mm can I remove per pass?
With K100 belt on soft wood: 0.3-0.5mm. On hardwood: 0.1-0.3mm. To remove more material, first use a thicknesser then sand.
What does "double pass" mean?
Working half the piece, turning it 180°, working the other half. Doubles the theoretical width but requires precision to avoid steps in the center.
230V or 400V: which to choose?
If you have three-phase power and work many hours a day, choose 400V for greater reliability. If you only have domestic 230V, single-phase models are still professional.
Is IntelliSand technology worth the extra cost?
Yes, if you work with different woods (resinous, hard, soft). The system automatically prevents burns. If you always work with the same wood, you can manually adjust with a Bernardo.
Can I sand MDF and chipboard?
Yes, all models work with MDF, chipboard, plywood, and solid wood. MDF generates a lot of fine dust – use adequate extraction and an FFP2/FFP3 mask.
