If you’ve been around paint, timber, or auto prep work for a while, you’ll recognise the work‑horse quality of the . This is a corded 150 mm random orbital sander that doesn’t mess about — it gets material off fast when you need it and leaves a finish that’s easier to level and prep. You don’t buy this for weekend tinkering, you pick it because you’ve got real work stacking up.

Here’s the thing: this isn’t a one‑trick pony. From rough cut sanding filler to mellowing down lacquer on a cabinet, the Bosch GEX 34‑150 sits in that sweet spot where power meets control. It’s not whisper‑quiet but man, you feel every bit of that 340 W input power under your hand — and that matters a lot when you’re trying to hit consistent surface results without gouging the workpiece.

Key Features:

• 150 mm Sanding Pad - Covers a larger footprint so you can smooth big areas without going over the same spot three times.
• Variable Speed Control - Lets you dial the rpm from low to high depending on what you’re working on.
• Multi‑Hole Sanding Pad - Works with various hole‑pattern abrasives to boost dust extraction on the move.
• Hook‑and‑Loop Fastening - Changes abrasive sheets in seconds with no fiddly clips or tools.
• Integrated Dust Handling - Plays nice with Bosch Click & Clean or a standalone dust box so your workspace doesn’t turn into a dust bowl.

Applications

This machine isn’t just for wood — though it’s ace at that. The random orbit action helps you tackle lacquer removal, between‑coat sanding on paint jobs, prepping fillers or even doing light work on mineral and acrylic surfaces with the right paper. It’ll smooth furniture, level edges and renaissance boards alike without leaving swirl marks if you set speed and grit right.

Why Choose This Model

In practice, this unit shines because of how it balances power, weight and feel. At around 2.1 kg, it’s solid without being arm‑breaking — which means you can run it all day without cramping up. The constant speed electronics keep it going at pace even under load, and that aluminium bearing flange means it doesn’t give up after a few tough jobs. If you want something that tackles both heavy stock removal and fine finishing without needing to swap tools, this is it.
