Repairing metal housing.

7/8" steel tube with ends slightly rounded inwards.
I need to remove all and a little more of the rounding inwards.

What material bit for either 1/4" OR 1/8" shank hand drill motor or
Dremel is best to use ?

I have many of these to do.

Can you just re-cut the end?
Maybe a step drill bit, or a conical bit.
(A dremel sounds a bit wimpy for the job, unless it's thin walled
SS.)

Did anyone mention a tapered reamer ? The pipe threading machines
usually
have them built in.

Do they work on rigid? pipe, too?

The taper reamer built in to the threading machine is used to deburr the
inside of the cut end of the pipe before threading . Should work on any
round metal tube withing the size range of the reamer . They also make
them intended for manual deburring . I even have one that fits in my
grandfather's brace .
