Can aluminum oxide filament be used on wood and painted surfaces?

Yes - it is the standard filament for wood brushing and paint preparation work.

Wood and coated surfaces need controlled, even cutting. Aluminum oxide grains are tough but not aggressively sharp, so they abrade the surface uniformly without digging in or tearing the grain structure.

Typical wood and coating jobs

• Raw wood texturing: Brushing raises a uniform grain pattern before staining or oiling.
• Between-coat scuffing: Fine grits knock down gloss and give the next coat a mechanical key.
• Old finish removal: Medium grits strip lacquer and paint efficiently without gouging the substrate.
• Edge and profile work: Thinner filaments follow mouldings and carved profiles evenly.

Setup tip

For furniture and cabinetry, 180# to 240# filament in 0.3 to 0.6 mm diameter covers most scuffing and prep. For stripping and heavy texture work, drop to 60# to 120#. Always test on offcuts first - wood hardness varies widely by species.
