Mibro 1/2 in. Diameter Cobalt Steel Drill Bit, 251511 is rated 1.0 out of 5 by 1.
Rated 1 out of 5 by from poor performance i bought the more expensive bit after the one that was supposed to last 6 times longer than regular took 15 minutes to drill thru 1/4" of steel. The more expensive bit never made it thru at all on the next hole. It took 30 minutes and 3 bits to drill one hole, even with the high dollar bit
