Most drill chuck clutches stop when the drill applies a certain measure of torque. If you’re using all the same fasteners and driving into exactly the same material, that translates to approximately the same drive depth. But Festool’s new FastFix “depth-stop” chuckstops at a fixed depth every time — no more worrying about variations in wood density.
Besides the depth stop setting, this is pretty much like any other chuck for screw driving. The bad news: it’s a member of the FastFix line, which means it only works with Festool cordless drills. Of course, we’re wondering when other manufacturers will follow suit and offer something like this.
