Achingly ignorant question: I am putting together gear for a knifemaking shop, and I realize that it's best to get the angle grinder with the best combination of power and form factor (trigger type, etc.) you can afford, but I was wondering one more thing.
Is it best to stick with a 4.5" grinder, or if I can buy a larger grinder, will it run smaller discs? I realize a 7" disc will eventually grind down to 4.5" but before I make any other assumptions and stick myself with too much grinder, I figured I'd ask you all.
Should I get the best combo of bigger, better amperage, and more comfortable trigger, etc., or is it better to stick with the 4.5" grinder to start with? Most of my work will use 4.5" discs, but I was lucky enough to get a gift card, and I want to make a good decision on this.
(Right now I'm using a 4.5" grinder I got for ten bucks after coupon at Harbor Fright, and once it croaks, I want to be ready to move on my next one since I use it constantly.)
I should also ask, should I consider a cordless, or do they eat batteries?
I appreciate all the smarts that you folks are sharing here, and when I have something to show off I'll let you know. Right now I'm working steadily towards making that first thing I'm not ashamed of.
Many thanks,
