STAHLWERK DES-125 ST 125 mm (4.92 in) air sander review

A one-kilogram 125 mm (4.92 in) air sander — light enough to work one-handed, which is what a long session on a vertical panel requires.

The last word One kilogram, published. On a tool held at arm’s length, that is the review.

What lands on the bench

A 125 mm (4.92 in) pneumatic random orbit sander weighing a stated 1 kg (2.2 lb), running to 11,000 rpm, for one-handed use.

Why the weight is the headline

Sanding a car is done standing up, often against vertical or overhead surfaces. Tool weight decides how long that is possible, and one kilogram is genuinely light for this class.

What is not stated

Orbit size — which decides the scratch pattern — and air consumption. Both are worth confirming before buying.

What it shares with the rest of the family

A compressor requirement this site does not cover, and abrasives sold separately.

Availability

Listed but with no offer on the American Amazon store — the reference exists there and nobody is currently selling it.

The questions that reach us

Does weight really matter on a sander?

More than anything else after the orbit. A kilogram held against a door for an hour is the difference between finishing a panel and stopping halfway, and it is why professional bodyshops care about it.

Can I use it on wood?

The maker states so. In practice a paint-orbit sander is fine on wood and a wood sander is too coarse for paint — the crossover works in one direction.
