I might get you on this one. Does anyone know the thread size for the collet nut of a Dremel Tool?

WAY off the wall I know but I would still like to know.

...looking at mine, I'd guess a FINE threaded 8mm

I tried a 5/16th fine thread and no go. It's definately fine thread and mm is my next guess. I measured the outside threads with calipers and come up with 7 mm. Who's got metric taps though??? :confused:

Sears sells new Dremel tools.......Easy! LOL

I couldn't even find a metric that would fit. It may be special to Dremel.

What you doing up now, holy cow everyone look out McLin is getting his Dremel Fixed........

Ahhhh that ol' guy can't leave anything alone. He is probably connecting a .21 with a tuned pipe up to it.

With him there is NO TELLING.

If I can get an answer, I promiss you will like it!

If You Are Talking About The But That Goes Over Top That Locks The Attachment Into Place. If Thats What Your Talking About Lowes Sells Them For Just A Couple Bucks Hope This Helps

Thanks but I'm not looking for the nut, I have that, I need the thread size.

I haven't stumped you guys have I?

7mm fine pitch
or
M7x.66mm

That is what my calipers told me...

Google is your friend:

7mm x 40TPI - yep, metric diameter with english thread pitch.

another reason to be sending that guy $35 a year..

I guess I jumped the gun on the pitch. I saw a number close to 2/3mm and went with it.... .66mm is about 38TPI. 40TPI is .635mm


+1 to Hank
+1 to sending him $35 a year to solve our "Problems"

McLin is building the 1st 1/10 scale hybrid out of his .12 car and a dremel.

Thanks guys for all the help now where the heck do I find a thread die like THAT LOL. BUT at least I have a starting point.

Oh and Mitch, I bet you are going to want one (actually two).

McLlin,
I dont think there is a class at the ROAR Oval Nats for nitro powered Dremel Tools. I mean, provisional classes are one thing, but you are pushing the limit with this one... LOL

But I'm only going to run 10% fuel !!!

Oh well, maybe I can work it out as a Spec class

You can run spec tires, also. But the fee will still be $80!!!!!!

LMAO Now THAT was funny!

this is too easy, i would tell pete or the racket, hey, let me borrow your dremel for a minute, and when i give it back say, oops, i lost the nut ,sorry

Nope, I didn't need the nut, I just needed the thread size so I could buy a die to thread another shaft. But it appears that I am going to have to go another directions with this project because no one that I could find makes one.

I bet Dremel makes one. Or has a supplier. Also, a well equiped machine shop should be able to cut you the parts you need.

Not sure that you are doing but what about using the cable attachment for the Dremels?

Well, I broke down and talked to a friend that is a designer and has access to a machine shop, it's a wonderful thing how a lathe dosen't know metric from american LOL He is going to cut my proto types.
