Ive got to replace a few panels on my project, (rear arch, small area of sill, part of A pillar etc)
All quite delicate areas, And id like to use a small cutting disc, Air cutting isnt an option as 1 i don't have a compressor, and 2 a compressor will take up too much room.
Has anyone had any luck using a dremel for this? And if so, what cutting discs did you use?

I have used a diamond cutting wheel in my dremel with some success, takes a bit of time, and with care, good results, you cant load the wheel as it burns out, you need to let the wheel do the work, I found the fibre wheels not much use, they last about 30 seconds,
I did wonder if coolant or some sort of oil might make the diamond disc last longer, but have more than 2 on standby.

The only problem with dremal cutting discs is they break very easy and often fly towards you face...
A thin cutting disc on grinder is far better.if worried about heat just do little bit's at a time

I'll echo the above, I use the small cutting wheels but they don't last more than a few inches, great if your removing something delicate but not so good if your cutting panels, as you get fed up of changing them, I'd much rather use a slitting disk in the angle grinder for most of the big cuts,

They are all shout and no trousers IMO, I've got one and tried to find a use for it, but other than the final dressing of welds right in tight corners (which would be better done with a proper die grinder) they are no use for bodywork at all. In fact as a general "DIY" tool they're mediocre at everything really.
If you are cutting a straight line they are hilariously slow, hard to keep a decent line, cumbersome and go through disks like nobodies business, just use a slitting disk in a grinder.
If you need a tight internal radius just use a slitting disk to get close, eek a bit closer by grinding it then finish with a file by hand to get it perfect.
If you need a small hole, drill it and file out by hand. Again, much quicker and more accurate than a dremel.
One thing to add though, if you are just wanting to cut things out delicately and put in small patches here and there, then you will just make your life harder in the long run. Just bite the bullet and cut out big chunks and the repair will end up better and longer lasting.

Cheers for the input guys, Ill go for the Grinder and slitting disc route then  Which to be fair is better for me as a i have load of cutting discs etc for the grinder but no bits for the dremmel ... I too would like to actually find a use for the dremel. It just sits in its box. I used it to cut some plexiglass with realy realy good results once... But that was it. Anyways.. Cheers again |
