The PS 13 is a small linear-motion detail sander. Its main buying questions are access, suitable abrasive supports and the required low-voltage power supply—not whether it can replace every larger sander.

Linear strokes, not rotary speed

Proxxon describes 8,000 strokes per minute with a 2.5 mm stroke. The earlier article incorrectly called this 8,000 RPM. The US manufacturer page lists approximately 130 g (0.29 lb), rather than the previous 14.5 oz figure. Compare those dimensions and the support shapes with the areas you need to reach.

Check the supply before ordering

The manufacturer lists 12–18 V DC operation and requires a compatible supply of at least 1.0 A. It recommends NG 2/S or NG 5/E supplies. Confirm the approved supply, regional mains version, connector and whether it is included in the seller’s package. Do not assume “12 V” means a cordless battery tool or permission to connect an arbitrary adapter.

Plan the abrasive shapes

Proxxon lists straight and angled sanding supports and preprofiled adhesive pads. Check the supplied and replacement shapes, available grits and backing format. Choose abrasives for the material and finish requirements. A support that reaches a corner does not guarantee that it will avoid rounding or removing detail.

Research conclusion

Consider the PS 13 when a small supported abrasive face is the feature your task requires. We have not measured finish quality, removal rate or hand fatigue, and do not claim that it cannot gouge a workpiece. The earlier workshop tests and comparative winner claims have been removed.
