FlexiClick Attachment GFA 12-W. Redefine your limits - flexibility through five solutions in a single compact tool. High flexibility - The GFA 12-W transforms the cordless screwdriver into an angle drill driver. Compatible with GSR 12V-15 FC. The "one-click" holder ensures an immediate secure connection with the tool. All other FlexiClick attachments can also be attached to the GFA 12-W, such as the quick-change chuck GFA 12-B. Compact design - The compact shape (head length: 61 mm) allows work in particularly tight spaces. Easy to use - The GFA 12-W can be locked in 16 different positions (360°) without having to remove the attachment from the cordless screwdriver.
