DeWalt 12mm Extreme 2 HSS Drill Bit is rated 4.4 out of 5 by 67.
Rated 5 out of 5 by from Impressed Slightly mistrust drill bits with anything other than a conventional cut head, but have to say I was very impressed how easy it was to drill 12mm holes through rsj (cut 8mm then 12mm with cordless drill) . Impossible to resharpen when blunt but seems to stay sharp for a good few holes

Rated 5 out of 5 by from The best drill bits These are expensive but they are so worth it. Big holes in a single cut through some tough and thick steel. You just can't go wrong with these things. I give them a lot of abuse and they last a long time

Rated 5 out of 5 by from I was dreading it!! I was absolutely dreading drilling 12mm holes in some steel supports had to drill about 14 holes this thing went through them like butter I've never used a bit like it I did 14 holes in less than an hour was expecting to take all afternoon!! don't bother with the cheap ones although a little expensive its worth it 100%!!

Rated 5 out of 5 by from Worked well on stainless steel Well-known dessert flowered two cheaper drill bits before biting the bullet and lashing out on the DeWalt bit! Bit head design allowed slower speed cutting through 2mm 316 stainless steel sheet again and again without getting hot enough to case harden the stainless, as the other bits seemed to do even with oil coolant spray.

Rated 4 out of 5 by from Drills holes Not the best but by no means the worst.. Does a good enough job for day to day drilling.
