Guys, English being my second language I'm struggling to find the name for the tool that is visible on the following photo :

It's in the bottom right hand side corner. I suspect it can be really handy for smoothing out the tobacco chamber

Tool?
@Karol
If your intent is to drill/bore the tobacco chamber with such an item, these will do the same job for much less money:

Some folks say they get chatter using this type of bit, but they always work fine for me.
If your intent is to use the burr freehand with a dremel or flexshaft to cleanup the tobacco chamber, you need a heck of a steady hand so as not to gouge pits.
@Ray
You're probably referring to these items:
They're very aggresive, so I rarely use them.

No thats not it. Those are what woodworkers call a rotary file.
Metalworking rotary files have a different cut, just like a metal file has a different cut than a wood rasp. If you look those giant burs up in a Machinist catalog like MSC, J&L, Enco etc. thay are often called rotary files once they get over a certain size. My MSC catalog is a couple years old 2004-2005 but on page 157&158 they have these listed as rotary files.
I don't know why they do this. Seems to me a bur is a bur no matter how big it is.

Oh yes, isn't that intriguing... It also looks almost finished, polished and all. Maybe that's the only way of reliably knowing (and following) the grain, but what do I know...Nick wrote:What I want to know is how that half shaped stumel came to be? It looks like it was turned on a lathe, buy how could you turn somthing in that way?
This is already OT, I just played around with the spade bit, made sure as best as I could that it's symmetrical, shortened it's shank significantly and skipped drilling the pilot hole. I firmly believe that the pilot I drilled before is the main reason for the chatter as without a material there is nothing to guide the bit. This time it went inside like a was drilling a block of butter.Karol wrote:Chatter is exactly the problem I have. Having said that I still need to experiment with what I have (modified spade bits) to find the best solution.
