Product Highlights

GMA 55 is the drywall screwdriver auto-feed attachment for faster and more comfortable working even in difficult positions thanks to its ergonomic design and light weight of less than 0.4 kg. With its thumbwheel, the depth setting can be adjusted quickly, and tool-less screw length adjustment is also possible. The open design facilitates cleaning and prevents dust deposits, thus increasing its lifetime.

Equipment & Application

GMA 55 is designed for drywall screws up to 5 mm in diameter and a length between 25 and 55 mm. It shows its strength in recurring work such as applying drywall panels to ceilings. GMA 55 is compatible with all Bosch Professional corded and cordless drywall screwdrivers like GTB 18V-45, GTB 12V-11, or GSR 18 V-EC TE.

Additional Information

The PowerSAVE mode of Bosch GTB 18V-45 Professional also works when GMA 55 is mounted. The package also contains a PH2 screwdriver bit (145 mm).
