David B2 Posted November 8, 2018 Report Share Posted November 8, 2018 I have recently used a Screwfix Dewalt Cobalt drill, stock number 2291V. 7.5mm but they do others in this series. Excellent drill with special pilot meant no need to centre punch and it worked Also hex shank. I used it to drill out spot welds and found it very long lasting. Still going strong after doing one whole floor/sills of a TR4A restoration. Although described as Cobalt HSS I found it significantly better than the so called special 8mm cobalt drills that are sold for spot weld removal. David B Quote Link to post Share on other sites
Lebro Posted November 8, 2018 Report Share Posted November 8, 2018 Sounds wrong, but try a masonry drill, they work surprisingly well with hard steel. Bob. Quote Link to post Share on other sites

Drewmotty Posted November 9, 2018 Report Share Posted November 9, 2018 (edited) Most locking wheel nuts are case hardened so a Dremel fitted with a grinding stone may be needed to take the hard skin off before attacking it with a drill. Ive had good results in the past by finding a spare bi hex socket a size under the one which will fit over the nut and smashing it onto the nut with a big hammer. By the time the socket has been forced over the nut the impacts will have helped free off the nut and a 1/2” drive “persuading” bar should spin it off. Let us know how you get on.

RogerH Posted November 9, 2018 Report Share Posted November 9, 2018 (edited) Hi John, these are good drills (see pic below) They are available as righthand, lefthand and straight fluted all in ONE drill. Very handy if you are not sure what to do. Roger Edited November 9, 2018 by RogerH Quote Link to post Share on other sites

Charlie D Posted November 9, 2018 Report Share Posted November 9, 2018 The easiest way to make your own “Roger drill bit” is to buy a normal drill bit from the pound shop, drill a hole in some very tough concrete (With hammer action and pushing as hard as you can until the drill bit binds solid) and then switch the drill to reverse. I’ve made several when putting up curtain poles. Charlie. Quote Link to post Share on other sites

Mark69 Posted November 10, 2018 Report Share Posted November 10, 2018 Plus1 for Irwin HSS, had a set for a couple of years good quality and last ages. Used on a regular basis. Quote Link to post Share on other sites
RogerH Posted November 10, 2018 Report Share Posted November 10, 2018 Hi Folks, not sure where my multi-fluted drill came from. recommendation - DO NOT BUY CHEAP drills. Most of the big names are good - Dormer, Irwin etc. The above drill 'picked up' in a piece of sheet steel. before I could turn the power off I had produced a work of art. I see from Stan's pic that the USA produce lefthand liquorice sticks. What do we get in the UK? Roger Quote Link to post Share on other sites

John. If you're not very careful they sign you up to a "free trial" of Prime, so you might want to cancel that membership before they start charging you. Pete Quote Link to post Share on other sites
