Bosch GEX 18V-125 0601372201 random orbital sander

Precision and control in finishing works

The GEX 18V-125 Professional cordless random orbital sander is a tool designed for demanding finishing tasks where a uniform finish and the absence of sanding marks are crucial. With a pad diameter of 125 mm and an oscillation diameter of 2.5 mm, the device ensures an optimal balance between material removal rate and finishing precision. This is particularly important when working with wood, veneer, lacquers, or fillers, where overly aggressive action could damage the substrate. The compact design and excellent balance allow for free movement even in hard-to-reach places, while the ergonomic handle minimizes hand fatigue during longer sanding sessions.

Brushless drive efficiency and application flexibility

The heart of this device is a brushless motor, which not only extends the tool's service life by eliminating carbon brush friction but also ensures constant power even at deep battery discharge. The user can adjust the rotational speed within a range of 6 000 to 10 000 min⁻¹ (corresponding to an oscillation speed of 12 000 – 20 000 min⁻¹), allowing for precise adjustment of operating parameters to the specific material:

• Lower speeds favor delicate polishing of lacquers or removing old coatings without overheating them.
• Higher speeds accelerate the intermediate sanding process of wood or mineral substrates.

The tool is compatible with the Bosch Professional Click & Clean dust extraction system, which significantly improves working conditions and visibility of the cutting zone. This system allows for the connection of an industrial vacuum cleaner or the use of the included dust bag, which is invaluable in enclosed spaces or during renovation work.

Assembly ergonomics and set completeness

Sandpaper mounting is quick and intuitive thanks to the hook-and-loop fastening system – simply press the material onto the pad to achieve a secure connection. The weight of the device body itself is only approximately 1.05 kg (without battery), making it one of the lighter models in its class and facilitating overhead or vertical work. It is also worth remembering the possibility of extending the manufacturer's warranty to 3 years by registering the product on the PRO360 portal within the first four weeks of purchase.

The set supplied with the tool contains everything necessary to start work immediately: the GEX 18V-125 Professional sander itself, a 125 mm diameter sanding pad, and one sheet of C430 Expert for Wood + Paint sandpaper (grit 120). A dust bag is also included in the set, allowing for basic protection of the working environment without the need to connect additional suction equipment. Thanks to the low vibration emission value (ah = 2.2 m/s²) and a noise level of approx. 63.5 dB(A), the tool meets high safety and working comfort standards for both professional carpenters and home users performing finishing renovations.
