thingiverse

I saw the files created by dj_abi Hand held drill press / drill guide. I wanted to create his parts but found they did not fit my Dewalt DCD771 Drill. I created my own design that is similar to his excellent design. Summary Simple drill guide for dewalt DCD771 drill or other hand drills with 48.5mm collar. The tool consists of two parts - Drill Guide Clamp that attaches to the drill and Drill guide base with two rods with stainless steel slides . The guide has 4 roller bearing imbedded in the design to assist the movement along the guide rods. The Drill Guide assembly doesn't work that well for setting the position of the hole as the drill chuck and the tool are quite loose and the drill will walk from the initial position. Center punch hole position, prior to using the 3d printed assembly. The 3d files were created with Solidworks and then saved as STL files.
