Best Bosch orbital sander

Updated: 21 October 2026

You want one Bosch sander for doors and furniture, and a cheaper alternative if you do not already own the batteries. The best Bosch orbital sander in this set depends on that condition. The highest star line is a GEX 18V-125 in an L-BOXX, at 4.8 from 2,029 amazon.co.uk reviews, and that kit is the wrong spend if you have no Professional 18 V packs. Prices are shelf prices on 19 October 2026. Peter F. used those listings and the UK review themes stored with them. This is not a lab test, and a qualifying purchase can earn a commission at no extra cost to you. The rows are on the [Bosch orbital sander](/hub/sanders/bosch-orbital-sander) comparison.

Best value if you own no Bosch batteries

The best value pick for a first corded 125 mm tool is the PEX 220 A, ASIN B0002KHIN0, at £48.49, rated 4.5 from 4,335 reviews. You plug it in. There is no pack to buy, and there is no speed control in the bullets. The PEX 400 AE at £105.00 is the corded step up when you want a dial. Its Amazon title says 350 W. The Bosch DIY page states 370 W and a 5 mm orbit, against 2.5 mm on the PEX 220 A. Keep both watt figures.

Top pick if you already own Professional 18 V

The top pick, when you already own Bosch Professional 18 V packs, is the GEX 18V-125, a 125 mm sander with a 2.5 mm orbit. The solo, B093TCNYR6, is £109.98, rated 4.7 from 1,061 reviews, with one grit-120 sheet and a dust bag, and no L-BOXX. The kit with L-BOXX 136, B093H12667, is £145.00, rated 4.8 from 2,029 reviews. The extra money is the case, not a battery. Bosch’s typical line is about 30 to 45 minutes on a ProCORE18V 4.0 Ah pack. That is an illustration, not a guaranteed runtime. Skip it if your packs are green. Price the pack on the cordless or corded page.

Who should buy something else

Buy the GSS 18V-13, at £227.91 and 4.7 from 460 reviews, for corners and cabinet faces if you already own Professional 18 V packs. One UK review says it ran on only two of six Bosch 18 V packs. The GEX 34-150 is the only 150 mm pad, at £200.00, 2.89 kg, 3.7 from 35 reviews, with a 4 mm orbit. The EasyOrbit 18V-10, at £69.00, is a 900 g body for green packs, and the title says there is no battery. The UniversalOrbit 18V-20 at £83.59 adds electronic speed selection. Neither is best value if you own no packs.

What best does not mean

Best here means the tool that matches the batteries you own, or the lack of them, for doors and furniture. It does not mean the highest star line, a lab test, or a runtime you can hold Bosch to. The PEX 400 AE’s 5 mm orbit is the faster corded scratch in this set. A 4.5 from 4,335 reviews is stronger evidence than a 4.4 from 59. If paint may contain lead, do not dry-sand it. The box and the bag are not a dust-free claim. That setup is on Bosch sander dust extraction.

Common questions

Which Bosch sander should I buy for furniture and doors?
If you own Bosch Professional 18 V batteries, buy a GEX 18V-125, solo or with the L-BOXX, and connect a vacuum when you sand indoors. If you own no Bosch batteries, buy the corded PEX 220 A and accept one speed. If the job is corners and cabinet frames, look at the GSS 18V-13 only when you already have blue packs.
Is the PEX 220 A still the one to buy if I have no batteries?
Yes, as the best value corded 125 mm tool in this set, at £48.49. You give up variable speed, and reviewers say the dust box and the hook-and-loop pad are the weak points. Choose the PEX 400 AE instead when you want the dial and you accept the Bosch 5 mm orbit and the £105.00 shelf price.
Is the GEX 18V-125 better than the PEX 400 AE?
Only when you already own Professional 18 V packs and you want to move between rooms. The PEX 400 AE is corded, lists variable speed, and carries a larger orbit on the Bosch DIY page. The GEX is lighter in the reviews and useless until a blue pack is fitted. Compare the full start-up cost, not the bare £109.98 or £145.00 figure, with £105.00 for the corded tool.
Why not buy the model with the most stars?
The 4.8 from 2,029 reviews is the GEX with L-BOXX. It is the same class of sander as the solo, plus a case, and it still excludes the battery. Stars do not add a green-battery fit, a 150 mm pad, or a dust box that reviews say was missing on the GEX 34-150.
Is the GSS the best Bosch orbital sander?
It is the best match in this set when you need a sheet orbital and three plates, and you own Professional 18 V batteries. It is a poor match for a plain door face, and at £227.91 without a battery it is not the value pick. One review also limits which Bosch 18 V packs it accepted.
Should I avoid the GEX 34-150?
Avoid it if you wanted a settled 125 mm tool. Consider it only if you want the 150 mm pad and you will check that the auxiliary handle and dust box named on the listing are actually in the carton. The star line is 3.7 from 35 reviews, and the listing weight is 2.89 kg.
