About this product
The Bosch GWG 12V-50 S is a cordless rotary grinder designed for grinding, deburring, sanding, cleaning and surface preparation, as well as removal of welding seams and points, particularly on metal. It is compatible with various 50mm grinding discs and with 6mm and 8mm collets, and runs on the Bosch Professional 12V battery system.
A brushless motor provides high torque and consistent performance, while a variable speed trigger switch with five speed modes allows precise control to suit different tasks. The compact, lightweight design with a small grip size suits tight spaces and overhead work, reducing fatigue during extended use.
A spindle-lock mechanism allows quick accessory changes. No-load speed ranges from 5,000-15,000rpm, and the tool weighs 0.53kg excluding battery. Supplied as a bare unit without battery, charger or case.
