I often use a brim on my prints , to improve adhesion .
However when I remove the brim from the completed print most of it comes away but a little (very sharp) part of the brim remains on the print.
I want to remove this part of the brim, is a be-burring tool usefull in this sort of aplication ?
 
Yep a de-burring tool is exactly what you want. You can carefully drag a stanley knife around the outside too but it can often chatter and isn't the safest method.

I use a Swiss Burr and a Noga, no real difference except the Swiss burr one is made of aluminium and cost more, the blades I have fit both tools.
 
Even better idea is stop using brims
A de-burrer is still a handy tool to have in general though. Sometimes I get a bit of a strange first layer that kind of spreads too much and I have to trim the sides off....yeah my crap settings but everything else is ok.

Sounds like 'elephant foot' maybe try easing the first layer height, so first layer is not so 'squished' into print bed.

Rather than listening to me and my waffle maybe google 'elephants foot 3D printing' you never know you might find a perfect solution.
 
you need to sort out your adhesion problems, not use brims
Note the "often". I do not always use brims, just on tall yet thin prints these are the ones I need to de-burr.
Never seen anyone yet say they never need brims when the print is tall and thin.

Using brims is an improvement I used to use rafts for EVERY print. :O)

I've done a couple of prints recently where a brim really is the only option. Quite tall, with narrow and thin bases.

/me goes to buy a de-burrer.

Any specific recommendations please folks (with links)?
This is pretty much the one I use Link one of the main brands is Noga so look around for something like that or Swiss burr, I quite like that one as it has quite a solid feel but is also quite slim.

There are loads on Amazon, make sure you buy blades or one that comes with some blades.
 
Saw this on Hackaday this morning that might be relevant

I've got that one, it does the job well though I did butcher the first item I used it on as I put too much pressure on it.
