Review: Fragile but good - Great bits but the smallest are extremely fragile. One of the three sets I received had the .1mm - .3mm snapped off in the unopened case because the bits weren't tightly bound by the cases built in bit holders. You'll want to inspect them closely when they arrive because the smallest bits are so tiny, it's difficult to even see them thru the case plastic
Review: Micro Drill Bits For the Win! - They're easy to break, but they do work with finesse! I bought these in an attempt to resize carburetor jets, and they worked wonders! The range in size is nice, and you get enough of all of them to break one and still be okay. Be careful with them, and they drill just fine.

### ⭐⭐⭐⭐ Nice micro drill set.
*by C***E on January 3, 2026*

Nice micro drill set. The more bits the better because they tend to break. There isnt anything they can do to prevent this because they're very small. Better to use a pin vice. They work great for model building.
