My local Canadian Tire is selling off a 5" 12 Amp angle grinder grinder for
$70. It seems too good to miss. However, I already have three 4.5" grinders
(two of them from CT also for ridiculous prices). Before I yield to the sale
fever, I thought I would ask:

What will a 5" grinder do that 4.5" will not?

My 5" DW831 Dewalt is built like a 7 or 9" grinder and is way more
comfortable to run than the 4 1/2" where you have to hold it by the motor
case. I do have a bunch of the Harbor Freight 4 1/2" grinders but I have
them set up with cutoff wheels or sandpaper discs and only use them for a
couple of minutes at a time.

I have five set up at the shop. Three 4-1/2" and two 9". The smaller
grinders are set up with a grinding wheel, a sanding flap wheel, and a .045
cutoff disc. The larger grinders are loaded with a grinding wheel and a cup
brush for de-scaling..

The only time I change anything is to put a small wire wheel on one of the
smaller grinders to reach a tough spot.
