what sort of pin is this?

[owas]

I still need to replace the pin for my mag drill and have found an image of pretty much the same thing,
ID on the sort of pin it is? (The one in the shaft, its a 10mm hole in mine)

Is it a dowel or a thread set screw?

Has it got thread in the middle so you can pull it out with a slide hammer?

No threads or anything, just a 10mm hole

Possibly it used some sort of "spring clip" that goes around the outside of the shaft and has a 10mm stub sticking out from the inside of the clip.

I think i've seen some somewhere but cant remember now......

This sort of thing but a bit rounder without too many "sticky out" bits.

just use a spring pin. Just a hollow pin with a slit in it to allow it to contract when pressed in giving it the ability to stay put unless drifted out.

we use them for everything in work and ive replaced all the loose fittings pins on my guns with them

Looks like a dog point set screw belongs in there. Possibly a wider than stock point. I'd take a set screw and turn the threads down off to the root.

is it not a shear pin designed to break and stop damage to the expensive bit of the machine should the broach snag

OK if it's not supposed to come out I would guess it's a dowel pin. The hole would be H7 and the pin is interference.

You can get a 10mm dowel pin with thread in the middle so you can use a slide hammer to get the dowel out if needed.

See PDF below of typical dowel pins with extraction thread

Looks to me like Wyn got it right.

Ah even more confused now haha.
To me the pin looks like its just to limit the spindle travel between the groove and keep the outer sleeve aligned with the inner shaft? Or am I missing something completely here
I have just ordered a 10mm roll pin.

It does actualy actually work fine without but thats probably the reason it got jammed in the first place ..

The pin will stop the inner and outer spinning relative to each other.

Without it they could jam up again.

You could even cut a bit of 10mm bar or a bolt..bung it in the hole and put a jubilee clip around it......as long as the inner shaft will slide up and down.

Got it, thanks for all the help,
It looks like I just have to have it going flush to the start of inside wall, so it doesn't affect the spring in there.
