Sorry about that Terry, even if it was the correct angle, even one of my home made ones would not be that rough, do you mean to say they where trying to sell that thing? Ian S C

That is poor….you going to name and shame?

Terry,

If that's the quality of construction … one has to wonder also about the materials !!

I understand your reluctance to name a specific supplier, because the problem is common across the trade; but it would be interesting to know (a) what they charged for this abomination, and (b) its manufacturer.

Elsewhere on this forum; Ketan has assured us that the quality of the Chinese machine tools has improved greatly over recent years [thanks largely to his own input, I suspect]. … But there are evidently serious problems elsewhere in the chain.

There is no doubt that the Chinese can and do make exquisite things [Apple computers being just one example] … So the problem is of our own making:

It is the clear responsibility of the UK importers and distributors to prevent "tools" like this reaching the market. They can do this by actively specifying what they wish to buy, instead of simply taking the cheapest available.

As John Ruskin put it:

"There is hardly anything in the world that some man can't make a little worse and sell a little cheaper, and the people who consider price only are this man's lawful prey.”

A quick look around the usual suspects and it would seen the cutter cost £3.17 but go to another supplier of better quality tooling and you will be looking at £11.97 assuming both are 3/8 – 10mm thats almost four times the cost

Its just the usual that you get what you pay for, if things are made to a price you won't get top quality at bargain basement prices.

Maybe the thread should be retitled "beware of cheaply bought lathe tools"

Every brazed tip tool that i have brought has required to be sharpened. This included a multi tip face milling cutter that came with a second hand mill, The first owner had tried the cutter and saild it was hopeless, i sharpened all the tips and find it cuts OK.

So my point is even if you ordered a 55 deqree point tool, i would not expect to use it without a touch up on the grinding wheel.

I know that this means they can supply the same tool what ever the angle you ordered.!!!

This only applies to brazed tip tooling tooling, HSS tooling i find if better finished.

I fully agree with Michael.

I use some brazed tipped tools on a couple of jobs where inserted tooling isn't suitable because of bulk.

I pay a lot more than £5 or £6 per tool but they still come semi finished, a quick lick on the diamond wheel soon gets them nice and sharp.

Jason is also correct in that you only get what you pay for.

Anyway I can't see much wrong with this threading tool other than a quick lick, if you are threading PG fittings even the angle is pretty good as they are 80 degrees

The first thread cutting tool I had was made from a bit of a square file, it worked quite well, its still in the lathe tool draw. I'v never used a carbide thread tool, and can't see a reason that I would require one. Ian S C

This tool doesn't need to be "touched up" as some people quote, it's a complete regrind if you have a Silicon carbide or diamond whel to hand. I'ts also irrelevant if some of you guys can grind a screw cutting tool in 5 minutes, a lot of people can't!

As has been said before I really don't think in some far eastern factories quality control exists, perhaps just a printer knocking out inspection certificates to assure us the tools we buy are within specification.

As Terry pointed out to start with it is the unsuspecting beginners that get ripped off. And this rubbish is going around third world countries where it might have been a days wages to a small jobbing repair shop.

Then on top it is damaging our balanceof payments and national debt to be importing rubbish. Even worse is all the shoddy toys and everyday objects our low income families and pensioners get foisted on them.

The way 'quality control' works is more obvious with electronics resistors. A 10% tolerance resistor is cheaper than a 5% tolerance one. This does not mean they make a special batch of cheap resistors. They make them all the same, test them, and the ones that don't meet 5% are sold as 10%. That means a 10% resistor is not somewhere between 0 & 10% it is guaranteed to be worse than 5% off value. There are then shiesters who buy up the 10% and retest them. Any that meet 6% they sell off as 5% to less careful manufacturers.
