Micro drill set
This gets the job done,but like virtually all Chinese products, it’s not quality controlled nor did it go through prototype or preproduction testing. Before using this set, one must check drill diameters with a digital caliper. The drill case which is a critical feature, works, but not smoothly and the index is not quite aligned properly. I’m satisfied but someone working with super precision will not be.
