Bosch PEX 400 AE Random Orbit Disc Sander 125mm

The Bosch PEX 400 AE is a 125mm random orbit disc sander designed for medium to large sanding and polishing tasks across a wide range of surfaces and materials.

Powered by a 370W motor with electronic speed preselection, the PEX 400 AE allows you to dial in the ideal orbital stroke rate — from 4,000 up to 26,000 opm — to suit the specific job and material. This makes it equally capable when working on wood, painted surfaces, varnish, plaster, and filler, as well as flat or curved profiles.

Weighing just 1.9kg, the tool is designed for comfortable use in any orientation, including horizontal, vertical, and overhead applications. A second handle provides additional guidance and control, while the low-vibration design reduces fatigue during extended use. The integrated Microfilter dust box helps manage dust at source, keeping the working area cleaner.
