This depth-stop is supported by a ball-bearing mounted bushing and stops rotating as soon as it touches the work-piece. The guide bushing is mounted on the stalk using a grub screw and depth is adjusted accordingly. Blind holes can thus always be drilled at the same wanted depth. The depth-stop is made from ABS and has an outer diameter of 65 mm. The guide bushing is made of steel.
Please note, that the depth stop stands 44 mm high, which has to be facilitated with respect to the drill. For larger depths, it is possible to mount the guide bushing in reverse, in order to obtain a larger adjustment of the depth-stop. Here the Forstner bit should be larger than the guide bushing, which has a diameter of 26 mm.
For use with Forstner bits the stalk diameter has to match the inner diameter of the bushing. The stalk being the upper part of the bit not entering the chuck.
