Well M7x1 is a standard tap?? It's in Reihe 3 of DIN13 Regelgewinde. Don't buy chinese garbage if you want an intelligent selection of products.

I can immediately say i need a 6mm tap drill for it without needing a library and an extra letter system of drills.

M7x1 is used for manifold studs on BMW's for example

I never saw it in a set yet but they are usually available seperatly.

M7 is also used for split wheels.

>DIN Norm is so based
using something else is heresy

BMW uses ISO bolt sizes, the should burn in hell
they sometimes mix it.

Swiss machines like Schaublin, Habegger or Hauser jig borers also used M7. As do some bike manufacturers.

>>2435812
>I got the advice to get a cheap-but-serviceable tap set, and replace individual pieces as needed.
That's generally the best way to do it but don't start out with a tap set not fitting your needs. There are great sets with M3,M4,M5,M6,M8,M10,M12 (sometimes also M10x1) and also including all the needed tap drills. I don't understand why there even are tap sets without the drills.

Start with something like pic rel. It was 30 bucks and much higher quality than the chinese kits. About the same as single taps i bought for more than half the price of the box. I never needed 3 taps per size.

You don't like bottoming?

Taps that is. Bottoming taps?

[Anonymous No.2435971]

>>2435946
Most taps i use are not super shallow tapered (machine taps) so if i need a thread close to the bottom i grind the center of. But now that i think of it that is actually super rare. Most of the threads i do are through holes and the rest is deep enough to tap further than i need and just use an appropriate screw length.

If i needed a thread really close to the bottom i would probably threadmill and don't bother with tapping.

Aerospace industry is exactly where the highest end 6 axis american made machines are, in hundred million dollar machine shops.
Your example of user error from navigational programming has nothing inherently to do with imperial system as a whole.
But the orbiter you are talking about was made using imperial machines, in shops that primarily use imperial unless specified otherwise.

But hey, im sure there is some consolation in the fact that india and vietnam, even africa have shops running all metric.

[Anonymous No.2437259]

are you actually retarded? NASA has been using metric for ages and the reason the orbitor crashed with no survivers was because the brainlets at lockheed used imperial for the navigation software

What are you talking about? There are barely any high end machines coming from the US. Maybe Fadal, Hurco and Hardinge. Maybe Brother is also American? Haas is big and they build great machines for your standard production but it's not high end. Gleason would also probably long be dead if they didn't buy Hurth, Pfauter and Mikron. Maybe some tool grinders like Anca.

Most high end machines come from Germany, Switzerland and Japan/Korea like Studer, Hermle, DMG Mori, Mazak, Okuma, Doosan, Studer, Chiron, Hedelius, Kern, Heller, Index, Weiler, Kellenberger, Matsuura, Makino and many more.

>>2437250
>Aerospace industry is exactly where the highest end 6 axis american made machines are, in hundred million dollar machine shops.

What you'll find in those shops are just named European and Asian brands and some older retrofitted US machines like VTLs or large grinders from companies long gone. And Haas where they are good enough for the requirements.

If you know better, please educate me but to me it seems US machine tool builders completely missed the huge jump from old conventional style machines with added controls to high accuracy pure CNC production machines in the 90s.

Haas is often patronized from arrogant German machinists but they recognized the huge demand for medium end low cost machining centers and filled that gap perfectly. I respect them for that and for giving small businesses or start ups a chance.

Not entirely true. The guidance system repeatedly warned that it was off-course and requested correction, and the management felt it was wrong, without ever delving into the details. It was dunning kruger: management didn't know enough to know they could be wrong.

While we're at it lets get rid of coarse and fine thread screws, its always a pain when you have the right size but the threads are different. Also there are too many sizes, OP is right we don't need m6 and m7. Shit while were at it, everything below m12 in size should be the same diameter. Would make smaller work a million times easier since any fastener would fit any nut/hole until you need industrial strength.

[Anonymous No.2440010]

American UNC and UNF is annoying to work with, but the worst threading metrics is clearly BSP. Who the hell thought it would be a good idea to take the worst from both metrics and imperial and change the thread angle to 55 degrees?

99% of all bolts and nuts in metric:
m6, m8 and m10 with m12 as honorary mention
nothing more required and they will be in the coarse thread or what we call normal thats nowhere as coarse as the rough threads on UNC, i cant even remember their thread pitch its just the normal one.
imperial is a clusterfuck of dimensions and thread pitches, some so close to metric you might accidentaly jam a metric nut onto an imperial bolt.

This is no different than imperial.
99% of the bolts you see are 1/4, 5/16, 3/8, and 1/2" in coarse.
And the pitches arent that hard to remember.

Just because you are ignorant doesnt mean the shit is hard.

[Anonymous No.2442707]

you go between pitches far more often than on metric, you never hear anyone here ask what pitch an m8 is, most dont even know it has others. and dont lecture me on imperial i actually work with that stuff daily.

You really don't. The ONLY common screw sizes where that might happen is 10-24 and 10-32.

[Anonymous No.2442780]

>>2442707
Just because you saw it in a book doesn't mean those sizes are actually used. They may have been at one time, and in certain applications there may be some odd sizes, usually because they started using them before pitches were standardized (meaning it's shit from 100 years ago), but in currant standard usage there are generally two pitches per thread diameter: a coarse one and a fine one.

Pipe threads are made up anyway.

A modern 1/2“ pipe is not even 1/2“ anymore.

The inner diameter used to be 1/2“ but they got better material to produce the pipes and could reduce wall thickness.

To keep the compatibility they sticked to the outer diameter. So we end up with some bullshit measurements for pipes.

>>2444784
Even worse when standard domestic copper piping is now 15mm and 22m and you end up with a mix of retarded fittings like 22mm x 3/4" or 15mm x 1/2" that requires differing coupler types just to put together
