This adjustable depth stop will hold any standard hex mount bit. By rotating the inner part relative to the outer, you can set the position of the sleeve that surrounds the bit. The idea is to provide an automatic depth stop when the sleeve reaches the surface. We will see this as a built-in feature in drywall screw guns a bit later.
