Good quality cheap replacement drills
Great price for replacement drills and at the price I'll use a few up before starting to sharpen them.

Small but sharp
I want to use these to drill rivet holes for 1/8" pop rivets. The holes are too small. Comparing sizes using a digital caliper, the size in mm is 3.15. The 1/8" drill bit measures 3.14mm when directly comparing back and forth twixt the two numerous times. The rivets read ~3.18mm. I use comparative readings as I do not have a micrometer. I compared the bits against a half dozen imperial bits from different manufacturers and got similar results. Therefore I believe these bits are undersized.

Item was as described
Bits work as expected to drill holes for 1/4"x20 nutserts.
