10PC Mixed PCB Print Circuit Board Carbide Micro Drill Bits 0.1mm-1.0mm

This set of miniature drills saved me some dollars a few times, after I botched a circuit board installation - no one wants to buy a new board or components after screwing up the soldering process. These drills were excellent in clearing out the remaining solder in the place where an IC chip assembly had been lifted - soldering wicks simply did not complete the job.One caveat - one has to be careful when handling the drills and applying pressure: don't over-force, don't bend, and don't torque them too much, and all will be well.Quite satisfied with these little tools.

Have machined brass and Delrin with these. Would buy again.

Worked perfectly for extracting a broken 3.5mm jack from my note 8!

These bits are pretty delicate but they get the job done. You can expect the two smallest bits to break no matter what, but the larger bits are ok as long as you've got some sort of press.They aren't labeled, so you should probably write the diameters on the collars when you get them.

would buy again.

amazing little bits. seem sharp and the plastic rings are great to spin in fingers.

These broke quite easily. Wouldn't buy again

Worked great for what i needed them for and for the price.
