As per title really. Imagine you've got a box with no lid on it. What tool would you use to grind out a weld that went right into the inside
corner of the box?
Obviously an angle grinder won't get in there - and a drill will just slip about all over the place.
Wasn't sure if I needed something like this:

But am not sure how well they will fare against MIG weld on 3mm steel...?!
A small grindstone will take forever to cut a weld in 3mm plate.
Depending on it's position, can you cut down it with a hacksaw?
I'm currently using a black and decker powerfile to tidy up some inside corner welds, problem is it's got a fixed radius on the end so it can't go past a certain point.
You'll be there for ever with a Dremel type tool and as you say it will wander about all over the place.
You could use a power file like this...
...but it still won't get right into the corner.
Question - why do you need to get the weld out of the internal corner? Most people just live with it there or design around it if necessary. e.g.
cut a chamfer on mating parts to clear the weld bead.

A good quality carbide burr in something like a Dremmel. Don't waste your time with stones or HSS burrs.
If it's a MIG weld then bear in mind this will be a bit harder than the mild steel plate and choose a burr
accordingly.
(MIG wire is harder than mild steel so that it stays straight during the feed process)

Die grinder with a carbide burr.
A good quality big carbide but single cut
Thanks for the feedback - I have used a (cheap) Dremel type grinding stone in the past with little success (when trying to cut out for mounting of a
master cylinder in the back plate of my pedal box) so did suspect 3mm mild - or MIG weld - would be too much for them...

+1 for the Carbide Burr in a die-grinder.
That's the right tool for the job, and will shift anything.
Can you get a flap-disk in there on an angle-grinder - that's surprising in what it will shift.

Drills aren't designed for sideways loading so you'll knacker it, eventually.
