Old stand drill - Restoration

Welcome to today's video where you saw the renovation of an old manual stand drill. These tools have a long history and development, they were developed to make the process of drilling and countersinking in the vertical plane easier and more efficient. As such, drills have undergone a long development. The first electric hand drill for mast installers was already assembled in 1896 by the German Wilhelm Emil Fein. It was an oil-filled drill in a cast iron box with a pair of wooden handles weighing 7.5 kilograms and rated at 45 watts. The first drill with a pistol grip was invented and patented in 1915 by Americans Duncan Black and Alonzo Decker. They were drills with an aluminum case with an input of 600 watts. Lighter drills with Bakelite handles spread across Europe in the 1930s thanks to the German companies Metabo and Bosh. It was only at the turn of the 1960s that high-speed universal electric motors began to be used and double insulation was introduced, thereby increasing work safety. Until then, insulation was only simple and rubber gloves and boots had to be used. The drills, which today, after more than a century of development, correspond to the purpose of use, have in common with Fein's only that they drill holes not only in steel, wood, plastic, but also in masonry and concrete. And that's all for today's video. If you liked our video and would like to see more interesting content, please like, subscribe, share with your friends and don't forget to leave a comment.
