The smaller the thread, the more accurate you need to size the hole. On sizes below M10 you can certainly feel a difference in torque required, for every change of 0.1mm in drill diameter. Once you go below M3, a change of 0.1mm can mean the difference between a tap breaking or not. I would say that if working on small scale workpieces and doing metric threads, a 0.1mm increment drill set up to 6mm is a necessity. From there up a drill set 6-12mm in 0.1mm increments is desirable, but if too expensive can be replaced by a 0.5mm increment set PLUS a small number of additional single drills in 0.1 increments to cover the ranges required for M8, M10 and M12 taps and a few 10ths above.
And yes you are right, one should indeed ream holes that are to be tapped with tapered pipe taps such as NPT for air and oil lines.

Despite the extra cost ,HHS is the set I would be inclined go with as I do a bit of tapping in stainless less and carbon steel taps are really not up to work in stainless for any period of time. However it is your pattern of use that would dictate the purchase. If you are going to use them with a lathe, the type with a center make axial alignment an easy task.
Choose a name brand of a well known manufacturer. I would be looking a buying taps & dies as I needed them paying attention to the wrenches and handles as those from even some of the better brands have some bloody annoying characteristic. The adjustable tap handles are a pain in the rrse as the non adjustable side will unscrew.
If a set is better to your liking a set of Gear wrench taps and dies made in Taiwan are very good value around the $80 mark but be aware the dies are button dies -no slit in the die nut.The up side is the the handle system is superb.
I would include a pic but cook wants me to go out with her so maybe later.

That's great Paul - thanks very much for going to that trouble!
Yairs, it has moved along quickly hasn't it? Stacks of good info though. I suppose pipeclay is right in that there's a lot of info there for a backyarder to digest, but that's ok, I can just filter it when it goes into the rabbit hole, and retrieve when necessary.
Graham - yes a pic of your set would be excellent please.Regards, FenceFurniture

Fence furniture,
Morrisman has posted the pic for us,ta Morrisman!
Theyare the set I have, and look at the bloody price . I paid $80 and thought I got them cheap. After fritzing around with some of the standard tap and die handles the Gear Wrench set are a pleasure to use as the handle is made to fit both the the die unit or the tap unit, both of which snap in.
The handle has a reversible ratchet built in and looks and feels like a bit of quality kit.
It is a wholly metric set and there is a imperial UNC/ UNF one available as well.
The vacuum moulded box has the home aperture for each tap and die named so you know exactly where to put them back.
The woeful set I got from H &F around the same price, have the dies fall out when you close the box.

Well Graham, by all accounts that would appear to be the way to go for a starter kit, and maybe add on a few imperials because I only really need a few sizes in them (1/4, 5/16, 3/8). More than likely I'd be doing them by hand as I don't run a conventional drill press (and they'll be few a far between as far as I can see).
What say the collective wisdom? To make it easy you could just give Graham's last post or Morrisman's post a "like".Regards, FenceFurniture

Yes, it briefly crossed my mind to make variant22 an offer, until I realised just that!
Hmmm, although I could buy the imperial set and have the handle and then pick up the metrics that are not used........surely the handles would be the same (either metric or imperial hole.....otherwise they'd have to make two different ones, which wouldn't make any sense)Regards, FenceFurniture

Correction
Correction.
Mr. Alzheimer let me down badly. The HSS set I purchased was from Hare and Forbes, not Carbatec ( Advertising executives of both businesses can PM me for bank details if they wish to voice their thanks in the time honoured manner ).
Having said all that, I suspect (but don't know), that equal deals are available out there and reading subsequent posts that would appear to be the case.
I have to say I am not up to speed on such things although I am not back in the dark ages. I did hear however that George V1 has passed on and some bird is on the throne.

Interesting. When you go to the Gasweld website the Metric set is still $63, but the 40 piece Imperial is $95. I guess that's because they make far fewer Imperials.
Looks like the Imperial set would cover what I need - UNC & UNF in the common sizes, but your comments are appreciated, as always.Regards, FenceFurniture

I go past that particular Gasweld every time I go into Newcastle for work.
Give me a yell if you want me to pick something up.

Chaps, a couple of Qs on that Gasweld set:
- I've looked and looked and I can't see what steel they are (and you'd think they would mention if it was HSS).
- Maybe it's been mentioned in today's plethora of posts, but Graham when you say they are button dies, so no slit, what is the implication of this please?
Cheers
