Rated 4 out of 5 by from 3mm Steel drilling Needed to drill holes in 3mm steel angle irons and my normal bits would not touch it. Bought 2 of these bits - First one has drilled 28 holes and looks like will do many more. Did the job!

Rated 2 out of 5 by from Fairly poor on metal studs Took 20 mins to make its way through a metal stud. Wore out the bit. Needed to replace it with a tungsten carbide bit which sailed through in a few seconds. Personally I wouldn’t waste my time with one of these on a proper metal drilling job.

Rated 3 out of 5 by from Good bit but don't last. I needed to fit some blinds into a window resess. Hit the steel lintel so went out and bought 2 x 5mm version of these bits. Tested them on a peice of 5mm steel first and the bit went through no problem. Steel lintel on the other hand, the bit wouldn't do the job. Both bits worn out without making even one hole. Followed the guidance ie drilled slow speed, applied gentle pressure, but no chance. Lintel 1 dewalt extreme 0. My advice for steel lintels: don't even try, look for a different kind of fixing.

Rated 5 out of 5 by from Highly recommended The ability to withstand heat means that cobalt bits perform for long periods without cooling or the need for cutting fluid.
