Note PLease be very carefull if you run these files I dont know your machines setup, It is recomended that you air run them first.

I used these files a couple of years ago to produce the prototype probe using Mach 2/3 and remember it all went ok, the profiling cuts use a 3mm cutter the spot drills it dont realy matter what size you use, the others just use a size suitable for the screws you intend using.
