You should use lube Ally tends to stick to the cutting teeth on hole saws.

Hi Folks,
I am now at the stage of needing to install the dashboard instruments on
my
boat rebuild. I have a choice of buying a custom panel or making one
myself
which is the preferred choice. I have a piece of 4mm aluminium sheet which
I
would like to use. Can anyone advise me on cutting circular holes in the
stuff. I have a 'Hole saw' set which describes its self as 'Bi-metal' It
works fine in wood and plastic. has anyone tried them on aluminium please?
Most of the holes will be for 2" instruments although there is a larger
Tacho which is approx 3.5 inches. any suggestions will be appreciated even
if they are of 'The don't even think about it' variety.
many thanks
Peter

thanks to all for the advice
