mike3739 Posted October 1, 2017 Report Share Posted October 1, 2017 Anyone bought any good sets recently ideally for drilling steel. Cheers Mike Quote Link to post Share on other sites
RogerH Posted October 1, 2017 Report Share Posted October 1, 2017 Hi Mike, these people supply to the model engineering brigade https://www.rdgtools.co.uk/acatalog/DRILL_SETS.html HSS will do you OK. The cobalt drills may be over the top for our meagre needs. Dormer drills are very good. I'm sure there are sets of these out there. What ever you do I would not recommend 'Draper' products.

Mark69 Posted October 1, 2017 Report Share Posted October 1, 2017 (edited) Been using a set of Urwin hss bits for the past 12 months both at work and in the garage. Excellent piece of kit. Edited October 1, 2017 by Mark69 Quote Link to post Share on other sites
Guest ntc Posted October 1, 2017 Report Share Posted October 1, 2017 Cobalt all day long imho Quote Link to post Share on other sites
RogerH Posted October 1, 2017 Report Share Posted October 1, 2017 Hi Neil, Cobalt drills are indeed top quality but one is paying for something that is not required. The cars are mild steel and Ali. A HSS drill will go through like a hot knife through butter. Roger Quote Link to post Share on other sites
Guest ntc Posted October 1, 2017 Report Share Posted October 1, 2017 Hi Roger The set I have is over ten years old never needed a sharpen the speed of use is what counts Quote Link to post Share on other sites
Ian Vincent Posted October 1, 2017 Report Share Posted October 1, 2017 I buy cheap drill sets whenever I see them on sale at places like Lidl. They usually last about 3 to four years by which time I have probably broken the small ones and I just buy another set. If I running a business, yes I'd buy quality but for what I use them for, the cheap ones do the job. Rgds Ian Quote Link to post Share on other sites

RogerH Posted October 1, 2017 Report Share Posted October 1, 2017 Hi Ian, this is what can happen to a cheap drill. This one is a Draper drill. It went from righthand twist to straight twist to lefthand twist in apprx 1 second. Roger Quote Link to post Share on other sites

timhum Posted October 1, 2017 Report Share Posted October 1, 2017 Cheap drills do not generally drill accurately sized holes, I do quite a lot of model engineering and try to only buy quality. Look for ground bits rather than rolled, they are not much more expensive, buy good bits of the sizes you want and don't waste money on sets. Tim Quote Link to post Share on other sites
Ian Vincent Posted October 1, 2017 Report Share Posted October 1, 2017 For what I do the drill bits I buy are fine. Other folks can make their own choices. The majority of my drilling is done using a bench drill and as mentioned by Neil, I run it at its slowest speed. Ive never had one unravel the way the one in your photo has Roger. What did you do to it? Rgds Ian Quote Link to post Share on other sites
RogerH Posted October 2, 2017 Report Share Posted October 2, 2017 Hi Iain, very simple really. I was drilling a piece of 1mm (19SWG) mild steel sheet and a reasonable speed and the drill tip caught on the edge as it broke though to the other side. The drill bit stop but the drill has momentum and ran on for less than a second. When I looked at the drill bit I couldn't believe my eyes. Never seen that before. Usually they snap. I bought some fairly expensive ones and have found that the flutes are too deep. This reduces the cross section area and are difficult to use in a electric hand drill. Probably OK for a pillar drill.

brian -r Posted October 2, 2017 Report Share Posted October 2, 2017 + 1 for Dormer HSS drill bits for most jobs. Used them for most of my working life in the electrical and engineering industries. allways performed well. Cheers brian Quote Link to post Share on other sites
RogerH Posted October 2, 2017 Report Share Posted October 2, 2017 Hi Brian, Dormer are an old establish company that produce quality engineering tools. Like with many things today, finding the items is getting more and more difficult when the market is flooded with cheap rubbish. Roger Quote Link to post Share on other sites
DaveN Posted October 5, 2017 Report Share Posted October 5, 2017 Presto are not too shabby either! We use them at work. IMO no need for the extra expense of cobalt tips, just get ’stove burners’. Get the cutting speed, feed and lube/ coolant right and they will cut through just about anything! Quote Link to post Share on other sites
pinky Posted October 6, 2017 Report Share Posted October 6, 2017 cobalt are a specialist drill and will tend to break/chip buy a set of drills, a grindstone, and learn how to put an edge on them at westlands a/c you were given 3 drills you learned to sharpen them quickly no holes no money pink Quote Link to post Share on other sites
mike3739 Posted October 6, 2017 Author Report Share Posted October 6, 2017 Cheers for all your replies. What a great source of knowledge on tap, drilling down them was good to read. Regards Mike Quote Link to post Share on other sites
