Cobalt Drill Bit 4mm (2 Pack) is rated 4.4 out of 5 by 88.
Rated 1 out of 5 by from 1.8mm not 2mm No good if you need to drill an accurate hole and the drill bit is over 11% out

Rated 5 out of 5 by from Happy with 12mm drill I've only used the drill in wood so far but it is sharp and runs true. Being cobalt I hope it will cope with steel too if I ever need it.

Rated 4 out of 5 by from Cobalt drill bit 8mm Drilled through metal no problems, I had to increase hole size of metal bracket which it did very well.

Rated 3 out of 5 by from Appears good but not helped my situation Bought Nov 19 - seems to be good quality. Bought to drill out a thick screw that has rusted fast, tried normal metal bits and instantly blunted them so thought this would be tougher, but it's not worked at all, even drilling slowly and for a few seconds at a time. They do recommend using a cooling agent which i didn't want to pay for so used a little wd40 instead. So in summary, can't really advise on the quality but feels well made
