I started with a .6 to 1.5mm set and then bought 10 pack replacements for some I did break, all from eBay.? I was drilling lots of small holes and was dulling them before I broke too many.? They probably would have been fine in a high RPM CNC machine but I could tell when they were getting a little dull in the lathe.? They were pretty affordable shipped from China, in the fifty to seventy five cents a piece range.? Several came with Chinese manufacture stickers over other stickers which revealed them to have originally been labeled as made in Japan.??♂??

There are also re-sharpened ones that are even cheaper. Unfortunately, one of the batches I bought were packaged with a piece of? plastic foam with the drills stuck into it, quite a few of them broke when the foam was removed. OTOH, I now have a lifetime supply of 1/8" carbide rods ?
