Sometimes you have those workpieces where you have to make a radius at the bottom or at the back of holes. Difficult to reach and difficult to machine. Metaaltechniek has a unique combination of machine and milling cutter that makes it possible to apply an even radius to the underside of holes. We also call this milling cutter the inverted umbrella milling machine. Watch the video and see if this can also be a solution to your problem!
