Can an ordinary vertical drill be changed to a U-drill?
I can't. Ordinary vertical drills are often used in machinery manufacturing and repair shops to process holes of small and medium-sized workpieces. The vertical drilling machine can feed automatically, while the U-drill can only be used to drill slots, not to point holes. Ordinary vertical drills cannot be changed into U-drills. U-drill is a kind of precision machining tool, which is often used for hole machining, broaching and broaching milling of metal materials and cutting of flexible materials.
