Festool DC UNI FF FastFix Adjustable Depth Stop
At a Glance: FastFix depth stop with 0.1mm adjustment increments and interchangeable 17mm and 23mm protective stop sleeves.
Achieve fast, repeatable and professional screwdriving results with the Festool DC UNI FF adjustable depth stop. Designed for Festool drills and cordless drills equipped with the FastFix interface, this versatile attachment allows screws to be driven to a precisely defined depth without repeatedly checking each fixing by hand. The screw head can be positioned flush with the surface, recessed into the material or left projecting by a controlled amount. An integrated claw coupling disengages the drive when the selected depth is reached, helping ensure uniform results across large-scale screwdriving applications. Two replaceable stop sleeves with rubberised protective rings are included, making the attachment particularly suitable for façade work, decking and screws fitted with sealing washers where both consistent depth and protection of the surrounding surface are essential.
The DC UNI FF combines fine 0.1mm depth adjustment with Festool's quick-change FastFix system. Once the required setting has been established, screws can be installed rapidly and consistently while the rubberised stop sleeve rests securely against the workpiece without slipping or leaving unwanted impressions.
