Our take on the Bosch 18V Cordless 5 in. Random Orbit Sander (GEX18V-125N)

The Bosch GEX18V-125N is a bare-tool 18V cordless random orbit sander with a 5 in. pad, a built-in dust collector and a detail-sanding setup. It runs on Bosch's 18V batteries, so it fits the same packs as the brand's cordless drills and saws. Cordless sanding means no cord to drag across a finished panel, at the cost of runtime and weight. The best new price is $163.40 at WowToolz as of November 3, 2026, and only one store lists it new, so there is little price competition to shop against.

Questions and answers

Is the Bosch GEX18V-125N worth it over a corded sander?
If you already own Bosch 18V batteries and sand away from outlets or on ladders, the cordless freedom is worth the premium. For bench work near power, a corded 5 in. random orbit sander costs less and runs all day.
Does it come with a battery and charger?
No. The N in the model name marks it as a bare tool, so you supply the Bosch 18V battery and charger. Budget for those if you are not already on the platform.
How long does it run on one battery?
Runtime depends on the pack: a compact 2.0Ah battery gives short finishing sessions, while a 4.0Ah or larger pack lasts longer. Expect the dust canister to need emptying before a big battery runs flat.
What size sanding discs does it take?
It uses standard 5 in. hook-and-loop random orbit discs, which are widely available. Buy a range of grits, since the pad size is common and discs are cheap.
Is $163.40 a good price?
WowToolz lists it at $163.40 as of November 3, 2026, and it is the only new listing, so there is no lower price to compare. That is a typical bare-tool price for a 5 in. cordless random orbit sander; watch for bundle deals if you still need batteries.
Where is the Bosch 18V Cordless 5 in. Random Orbit Sander (GEX18V-125N) cheapest?
At WowToolz, for $163.40, as of our latest check.
