The cordless multifunction grinder is designed for cutting and separating wooden materials, plastics, plasterboard and soft metals (eg copper, aluminum, unhardened nails, soft metal alloys) as well as for rasping, grinding and scraping smaller areas. The tool allows you to perform precise work in hard-to-reach places, such as making cuts in the corners of furniture, tiles, etc. Its main advantage is the battery drive, which allows you to take the grinder with you where ever you need to work with it. For normal work, one or two 2000mAh batteries are enough, these can quickly charge in a quick charger. For heavy duty work, we recommend larger batteries with a capacity of 4000mAh. The batteries can be interchanged with all tools from the EXTOL SHARE20V series. Thanks to the Li-ion technology used, it can be recharged at any time without reducing its capacity. The Li-ion battery has minimal self-discharge and lasts a long time when charged and ready for use.
