i bought an seamless stainless steel tub with OD of 10mm and ID of 8mm,
that tube will serve me in my project , rifling it.
tried to fit 7.9mm rod(the cutter) in the tube and he fit exactly and not stuck, week after i did the same test but the same rod wont fit ,the tube and the rod was in place that is impossible to drop or get hit.

any thoughts ?

It will make cause the tube to expand, enabling the rod to fit in.
When it cools down the rod may get stuck however.

Where'd you get the tube at? Do they have big sizes also?
