which dremel bit to enlarge a metal lensboard?

[eric]

Hi all,
Gonna replace my Dremel with a Dremel 4000. Oh yeah!!! I'm also thinking of getting the Workstation that holds the Dremel and can be used like a drill press.

Anyway, I have some Linhof boards #3 that I need enlarged a bit. Any suggestions which sanding bit to use??

I've always just used a curved hand file, they are only aluminium boards and so very easy to file out. If you use the Dremel just one of the grinding stones.

DRE115 High Speed Cutter well with aluminum.

I would also do this by hand with a file.... but I'm not American!

I've used the "geenral purpose cutting tool shown at the Dremel site for enlarging holes on wood and aluminum boards. Although it tends to wreck the bit, I've used it on thin steel boards too. Then finish with a curved file to get smooth circle.

Oh my! Maybe I should use a Dremel or hand tools instead of having a co-worker use his milling machines and drill presses in his garage on the weekends! Silly me!

I've clogged up dremels pretty good with aluminum; using the can shaped stone/porous grinding bits. Seeking other's suggestions for bit choice is indeed wise.

I'd either file it out by hand, or use a milling bit in a drill press. If you're going to use a drill press though, a normal hole-saw kit works well if you oil things while cutting.

I find you can purchase stones for sharpening chain saw chains that work fine in a dremel tool and are cheaper.

You could always take your inspiration from Homer Simpson and blast the hole bigger with fireworks.

For a task like this, you will be much better off with a file.
