The GEX 12V-77 is a high performance spot sander which has a brushless motor and is part of the Bosch Professional 12v battery system.

Please note this sander will not work with 12v or 10.8v batteries from the Bosch Home and Garden (Green) ranges. The HMI control panel allows for fine tuning of the speed level and shows the battery status so you can keep an eye on remaining runtime while working.
