DeWalt 7mm Extreme 2 HSS Drill Bit 4.7 5 6 6
Great bit, high price Very tough bit. The best money can buy. Doesn't save you money, but will save your time and health. 2 Apr 2015
OK but do not overheat This is a good drill on mild steel, on stainless I found it overheated and became blunt quite quickly 28 Jan 2015
does the job, very hard! What can I say? it's a drillbit. Unusual tip shape helps stop it wandering on hard surfaces, lasts very well, seems well made, will be buying more as I need them, especially as 7mm seems to be the size most sets exclude for some strange reason. 3 Dec 2014
Works on cast iron. I had to shorten some lengths of cast iron guttering and needed holes for the fixings. Normal bits would barely touch the cast iron. One of these bits did the job although it did take about an hour for each hole! Not sure I'd want to do it often but will definitely be using these bits if I do. Trick I found is to do it slowly and let the bit cool down regularly as it seems to cut better when cold. 23 Jul 2013
