When it earns a place in your kit

Useful on case panels and desktop faces. A sanding block remains useful for edges and small details; sanding is not a way to correct a badly fitted case.

What to check before choosing

  • Match disc diameter, attachment and dust-hole pattern to the pad.
  • Check hose adapters and extraction compatibility before choosing accessories.

A practical setup sequence

  1. Secure the work and connect the dust collection specified for the tool. Inspect the pad and fit a suitable disc with aligned dust openings.

  2. Use the manual’s start, contact and stop procedure. Keep the pad flat and avoid dwelling on an edge.

  3. Inspect under raking light between grits and stop before cutting through a veneered face. Test the complete preparation on an offcut.

A common mistake to avoid

Pressing harder or tipping the pad can leave uneven areas; more sanding can expose the core beneath a thin face veneer.
