At home, you can easily make an almost original key holder for the three-jaw drill chuck. It will always be kept at hand in this way. To make, it is enough to clamp a complex piece of thicker rubber or plastic with rivets on the power cord, oval-shaped with two star-shaped holes. It is easy to insert the key into the star-shaped cutouts, it can also be removed quickly, and it will not fall out while working with a drill.
