    be very carefull when using the smaller drill bits! However, the bigger two of the three is what really worked for me in cutting steel. The bigger of the two extractors actually came in very handy as well. they are nice, yes and they do work once u use em correctly!!! ensure ur hole is deep enough, set the extractor in place and use a hammer to knock it in the hole and then u can use a socket (as i did) and turn in the left-hand direction (like ur pulling a bolt) and have ur stud extracted. when i used the hammer to knock in the etractors, i thought they would be damaged but they seem to be very durable. !!! it didnt work 100% of the time for me but it worked.

    I have used these a few times now to provide a 'true' centre when drilling pilot holes through countersunk metal parts into wood; for instance when fitting door hinges, door handles, guard plates on worktops, etc. and I am very happy with them. When they arrived I oiled them (just in case) and I use them at a slow speed with no problems.

    Just... I mean it's like a zillion drill bits for not a zillion dollars. Maybe this summer when the weather gets nice I'll join the local lemonade stand co-op and sell drill bits to passing dads.

    Great selection and a good price. Such a great idea. Do not fit a hinge without using one of these.

    It's not easy to find high-quality left-hand drill bit sets - several that I have tried are cheaply-made and not strong enough to cut through harder bolts. The Kkmoon set is a notable exception - the bits are strong (and don't bend under pressure) and cobalt reinforced to cut through steel.

    Fast drilling in sheet metal & wood... 99 bits for the price is great and you can download a drill size conversion chart off the internet and use these metrics instead of fractional. At .0028" or so difference, the screw will never know.
