No one is older than me. I have a YOUNGER brother named Methuselah, who incidentally invented dirt! This makes me OLDER than dirt! So quit complaining. You could be older than me, but you're not!

I have an Omega compressor. If you're a fellow Guild member, and you pass through Roswell, NM, I'll fill your portable tank as a courtesy.

Check OSG,

YG-1 Recomendation data, (they also make a very good tap, reasonably priced):

Fluid: Castrol Moly-D

You may need to use series taps, and if machining use- a forming tap, all depends on what you are needing.

After listening to you old timers, I feels like a spring chicken. ::)

If you go to the local hardware store and get taps/dies, they are going to be crap. This is from personal experience as a hobby machinist/budget minded.
Go with HSS taps and dies, preferably US made, the difference truly night and day. Especially with the smaller diameter taps like 8-32 and below. If you are making a part and you break a tap in it, you’re screwed. Its not impossible to get it out – they make tap extractors, but they aren’t guaranteed to get the thing out.

Also, there are 3 different types of taps: taper, plug and bottom. Ideally, you’d want each tap type for every size tap you have. You can also buy dies that work in pairs, run the roughing die over the rod to get shallow threads cut, then run the finishing die over the rod to cut threads to depth.

Being budget oriented, this is how I would spend my money:
Taps: get lightly used/new US made HSS taps off ebay or craigslist.
Drill bits: make sure you have the correct size drill bit for the tap you are using.
Dies: You can cheap out on dies, they are significantly harder to break/poor ones still work.
Tap handle: don’t use a ratchet or an impact driver, get a ratcheting tap handle. They Chinese brands wiggle and I stopped using mine after tapping a hole with it, bought a Starrett one off ebay and its sweet.

Also, if shopping on ebay, search for hand taps. CNC machines will use taps designed for power tapping, they don’t work well by hand. I have a tapmatic reversing tapping head for my mini mill, range from 4-40 to 1/4” taps but I got it for a great deal and wouldn’t recommend buying one unless you have a drill press/mill and need to tap a lot of holes.

Awesome!

Somewhere in the world is a Moto Guzzi Eldorado frame I broke a Hard as hell Easyout in. I tried in vain to remove it and finally gave up. Breaking a tap would probably be as bad.

No more Chinese Taps and Dies. I’m done with them.

Hanson Due wasn’t too bad, but their handle is garbage.

I’ve decided to not buy a set, rather buy only the size I need at the time. And thanks for the infinity on different types of taps.

Great post, thanks!
