### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    sharp and holds up
  

*by J***N on Reviewed in the United States on July 15, 2023*

I bought 2 of these and they hold up well which is hard to find for medal bits :)

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Small but sharp
  

*by K***N on Reviewed in the United States on April 16, 2023*

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.

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