Same summary
This cordless random orbital sander Bosch GEX 12V-125 Professional is designed for those who need cordless mobility and reliable processing of wood or metal surfaces. As it only comes with the tool without battery and charger, the product is more suitable for users who already use the Bosch Professional 12 V battery system. With a disc diameter of 125 mm, it is a good choice for more precise work and sanding small to medium-sized surfaces.
For more intensive or longer work, it is necessary to arrange for appropriate battery support in advance, as the product itself does not include a battery and charger. However, the mobility and compact design are an advantage, especially when working in the field or at height, where the cable hinders movement.
