Thread mill to match Radial pin

[robbycar]

Does anyone know if this is a thing?

Would love to live thread a Radial shaft like I do for some other pins.

You'll need to have someone custom make the tool for you. And you'll need a CNC lathe, since the thread pitch is deliberately odd.

 

[robbycar]

Yeah, I have a CNC lathe, just need the cutter!

I would reach out to Harvey tool, they can make small batches of thread mills.

I has last piece. Cutter tip OD 5/16”.neck diameter 0.153”, Shank diameter 1/4”.
$70 per piece plus shipping.

Cuefits, i think he needs the opposite mating cutter, not the one you showed.
(Unless i mistake OP's Q)

Is your (Cuefits) cutter HSS or micrograin carbide?

[metalware10]

It’s solid carbide

How you make internal threads with that?

You better have a nice cnc lathe.
Can't do 7.45 TPI on any manual lathe

for external thread. Sheldon one is for internal thread.

To make your own screws?

Delrin JP's if you can get that 7.5 ish tpi

So what use is it. If I'm making radial pins there are much more efficient tools for the purpose.

My setup for live threading on a hightower lathe would work nicely for this application along with the cutter Sheldon showed. You could use a pin and have to watch the limits closely but it would be cheap and easy.

what diameter is that?

 

[Coos Cues]

what diameter is that?

It looks plenty small to fit inside a 5/16 plus or minus hole

I was just thinking the shank must be at least .250, cutter od looks a little bigger, not much. Seems like a pretty flimsy tool considering it must use a full bit for correct form, being that skinny and that long.

For shaft threads, you don't need to go more than 1 1/4.
That's surely not for joint screw install that needs to go some 2 inches.
