Incidentally I’m still baffled as to why the big mains powered 1100W GSB drill has 40NM of torque and my impact driver has way more. I’ve got a new cordless drill on the way and that has 65NM…
The corded the OP was using is capable of 40Nm of torque, which is quite a bit. I have owned the same model for maybe 10 years now (?) and it can deal with drilling 26mm lock mortise holes in dry English oak, providing my bit is razor sharp, I run very slowly and I reverse the bit out and clear the waste regularly. Having a nice polished bit without rust (so any bit which has been used recently) helps. I suspect the OP's biggest issue is that he is choking the bit, but I'm here not there looking over his shoulder, so it's difficult to be 100% certainYou need a huge amount of torque to drill a screw thread auger bit.
I tend to buy big name augers when needed (but not for a couple of years now - these days it is just a case of replacing loaners which haven't been returned, or which come back damaged) and I've often sharpened before first use. I always dry and oil tem after use, especially on oak and walnut which will csuse them to rust quickly if left unprotected) and I resharpen them regularly (well, you gotta have a hobby) simply because it's proved a reliable approach over the years.I buy Erbauer router bits and they are fantastic, superior in my opinion to Trend.)
Yes, that works, but a single auger bit file is a lot easier and faster to use - providing you can source one (zee above). Since Nicholson's stopped doing theirs a few years back they have been difficult and relatively expensive to sourceI would get a set of needle files and sharpen your auger
And any money it gets really hot if you drive it at anywhere near the maximum torque for more than a few minutes. Continuous torque isn't the same thing as (momentary) maximum torqueI’ve got a new cordless drill on the way and that has 65NM…
Hate to disagree Notch7 but I think you could, Drill 1.5 to 2 inches with 24mm, then another inch with 12mm then pilot the length with 6mm, follow on with 12mm it should self cut without the tip and likewise with the 24mm.No you can’t.
Or maybe the lands are filled with waste? You aren't going to be able to drill all that far in solid oak without reversing the bit out and clearing it from time to time.
Short, sharp (no pun intended) and to the point. For general work you don't absolutely need the diamond card file (a few hundred years worth of woodworkwrs did without them, after all). The biggest aggro is getting hold of an auger bit file - try Workshop Heaven or Amazon
Not if the bit was jammed solid with swarf. See my comments above
You could just rub some candle wax on the outsides of the bit (not the cutting edge) and maybe treat the lands with something like dry lubricant (PTFE spray) or even furniture polish (basically paraffin wax)
Well said! For indoor use I wouldn't have recommended it, but the OP is drilling oak sleepers which will be used outdoors and are likely to be a bit damp, so contamination is probably not as much of an issue. TBH I was thinking more about the old style spray wax polishes like those that Johnsons do (or is that "did"?)However... when you say furniture polish, I guess you don't mean the likes of Mr Sheen? I was under the impression that they have silicone.
