Thanks,

Now that I have figured out which is the best size...

Are dust protection caps worth the extra $$ ?

I plan on a router table to cut aluminum, but know wood and other
things will be cut as well.

Also, it seems the best deal is on a 4 meter shaft, but I need four
lengths that are 1 meter each. Will I screw it up if I use my chop
saw ? with water cooling ?
