Gunsmithing Threading tools?

[Brodie]

Wondering if these would be good choices for threading tools. I'd like to buy from grizzly as I have some other things to buy there. Thanks for the help.

They'll work fine. Carbide would be better but as long as you're not hogging material off they'll work great.

Was curious if you could use different inserts on those for standard turning. Looks almost like it would work, which would be cool, you could just change inserts instead of the entire tool holder.

I have the second and third, they work well, reasonably priced. Go for it.

You guys are fancy, I grind mine from HSS Blanks

Re: Threading tools?

thanks for the advice everyone I appreciate it. Thought I would check before spending the cash.
kraigWY, we use HSS for almost all of our lathe work in the 8 month machining course I've been taking, we were taught how to grind all our toolbits and although I'm not bad at it there is no way I can compete with carbide inserts. There are very few of the students who can grind a good toolbit, especially for threading.

HSS bits are cheap. Insertable carbide holders are expensive, and so are inserts. A student that crashes a lathe with a $4 bit is more acceptable than a student crashing a $80 holder and a $15 insert.

Its a shame really. The vocational schools say they are preparing you for working in a machining industry. But they teach and train you with almost ancient technology compared to whats in a shop today. I realize not all shops are completely CNC, and even CNC shops have manual machines, but training a newbie ONLY to use HSS and grind their own bits is outdated.

In any shop, getting something done is priority one. Changing a insert takes about 30 seconds, and the geometry is perfect. Grinding that HSS takes longer, harder to get perfect-never mind the fact you can't run HSS as hard and fast as carbide.

I think its important to know how to grind a bit, but it shouldn't be the entire focus of tooling.

Teaches them what is happening versus just hitting a button and the miraculously it is done. Have to understand what is being done to make it happen. Old school is not dead, lol.

Re: Threading tools?

I get what your saying and I hope you appreciate that there's a great deal more to programming, setting up, and operating a milling/turning center than waving a wand and "allapeanutbuttersandwhiches"; a miracle. . .

If only it were that simple.

Re: Threading tools?

No, old school isn't dead. But it's still old school, and there is new technology. I went through a vocational program about 11 years ago. In the 14 months I was there, the only time I ever touched carbide tooling was running a CNC lathe. Time spent on manual mills and lathes was with nothing but HSS. CNC mill? HSS.

The point I was trying to make, and it wasn't that carbide is magic, and that CNC makes everything infintely easier, is that some schools fail to incoporate modern technology into the cirriculum.

I have more than appreciation for setting up, programming, and operation of CNC equipment. I have been doing it for almost ten years.

Re: Threading tools?

Understood, and learning the programming IS an art. I just picked up a CNC mill and will wind my ass and scratch my watch for awhile, buy a manual, beg for help and make it work....I hope
