Mibro 17-Piece Cobalt Steel Drill Bit Set is rated 3.5 out of 5 by 2.
Rated 2 out of 5 by from Not worth the money I got this set to try and drill out some broke bolts on a few projects i had piling up. Not a single bit would even throw a shaving unless i started hitting the aluminum casing. I figured maybe these are just some crazy hard 1/4" bolts so i tried drilling through a scrap piece of angle that i had and got the same result. Not drilling. Yes i was keeping the bits cool. Only reason for 2 stars and not 1 is that i like the case.
