This eccentric chuck locks onto any of Festool's drills with a slide-on battery and allows work right up to adjacent surfaces on a parallel axis to the main spindle. Ideal for driving fasteners adjacent to walls or other obstructions, such as when installing cabinets.

To attach, slide the eccentric chuck onto the drill and turn the blue collar to secure it. To rotate, simply rotate the green collar; there is no need to remove the attachment from the drill as with previous versions.

Accepts 1/4 inch hex shank bits.
