Review: I cleared a stripped screw head using one of these bits - I cleared a stripped screw head using one of these bits and it took me less than 20 seconds. I had previously tried using several different extractors and none worked. One of these bits was literally the only way I could remove the screw. For note taking purposes, the screw belonged to a door knob and was also warped. I am happy with the quality of all of the drill bits. Mine came slightly lubricated with some kind of machine oil. The affordability of these cobalt drill bits is excellent and their performance is even better. The speed that I was able to remove the stripped screw with was amazing. I literally drilled into it and the lingering stuck knob literally fell off. If all else fails and you're trying to remove a stripped or warped screw, try using these bits to help you out.
Review: Good Quality - Good quality bits, cut easily and accurately (photo). My usual test for cobalt bits is stainless steel, these bits cut through as easily as mild steel. Run them slow, and dip into water periodically to cool off if you have thick material. It’s also a good idea to use Tap Magic cutting fluid to reduce friction, and thus keep the bits cooler. Good price, happy with purchase.
