Search "cabinet sander" and every guide tells you the same thing: buy a random orbital. That advice is fine for refinishing one kitchen. It's wrong for anyone sanding cabinets for a living — and it's why the doors coming out of production shops feel better than DIY ones. Professional shops don't hand-sand raised panels with an orbital pad; they run brush sanding machines that sand the face, the profile and the inside edge of a cabinet door in one pass. QuickWood has built those machines since 1975.
For a single refinish, a random orbital handles the flat faces — but orbitals can't follow the profile of a raised-panel door, which is where refinishes go wrong. Two tools close that gap for under the cost of a good orbital: the drill-attached flap wheel, which chucks into your drill and conforms to routed profiles and panel raises, and sanding sponges for inside corners and detail work between coats. The sequence: degrease, orbital the flats at 120–150, flap-wheel the profiles, sponge the corners, then 220 before primer or stain.
A production cabinet shop measures sanding in doors per hour, and hand tools don't scale. QuickWood cabinet sanding machines run flexible flap wheels over the entire door — flats, raises, coves and edges — in a single feed \u2014 see the full range of door sanding machines. Shops run them for raw-wood sanding before stain, denibbing between coats, and sealer sanding before topcoat: the three passes that separate a production door from a furniture-grade one, and the reason factory cabinets feel like glass. That sealer pass at 240–320 grit is also how shops handle polishing cabinet surfaces before the final coat.
Profiles keep their shape — flexible flaps wrap the moulded detail where rigid pads flatten it. No swirl marks — brush heads sand with the grain at consistent pressure, so no orbital squiggles telegraph through stain. And one operator feeds hundreds of doors while the machine holds the quality.

For a one-off refinish: a random orbital for flats plus a drill-mounted flap wheel for profiles. For a shop: a brush sanding machine — it's what production cabinet makers run because it sands profiled doors without destroying the detail.
120–150 for bare wood or paint prep, 180–220 before primer or stain, 240–320 for sealer sanding between coats.
For real results, pull the doors. Sanding in place fights gravity, misses edges, and fills your kitchen with dust. Doors on a bench — or through a machine — get done in a fraction of the time.
Sealer sanding — running the sealed door back through fine-grit brush heads before the topcoat. It's the step DIY guides skip and the reason factory doors feel like glass.
