As far as I can see there is no difference between the two chainsaw files show. Both are 5/32" or .1526" (3.87604mm) the #19 drill is .166" (or 4.2164mm)....so the chainsaw files are smaller by .010" or so. The #19 drill bit cleaned out more plastic than I would have thought. I tried to put the pins in after having run the drill in forward only...they went through but had a few snags. Once I ran the drill backwards....they fell right through.
