One reason that I pointed out German and Swiss micro drills is that you can get them in cobalt and HSS.? They flex while the cheap (typically Chinese) carbide bits will break.??
This is where I disagree with some of what has been discussed here.? Say that I want to make one of these spade type of drills, .020.? So I have to get drill rod and somehow file or grind it in half, then put a point on, and heat to harden?? I may or may not be able to do this - we do not all have the same skills.? And at some time I might have lost my interest in drilling a hole after all of that.? It is just my way of working.? Make a hole?? Take a drill out of the index, or out of a package of micro drills, or maybe from the big box of unknown, unused drills.
Model trains is my main hobby.? And cameras, collecting fishing stuff, etc.? Now I have a number of small machines.? Some get used frequently.? Others have never been used? -- they were too good to leave.
