Review on Uxcell Drilling Cobalt Metric Spiral by Jacob Diego
NOT 3mm! 3.4mm is so useless when size really matters
I bought these to drill and cut aluminum. I noticed right away that the beats felt big. I measured with a caliper that was 0.4mm larger than the drill that came with the tap (which was 3.05mm). 0.4mm is a large margin for such a small bit, making them completely unusable for threading.
Pros
- Tools and Housewares
Cons
- Something Else
