I have burnt through HF grinders and decided to spend a little more and got a 6 amp makita that worked fine for a couple years. Then last week the spindle lock broke trying to get the cutoff disk out.
I saw rigid makes a cordless angle grinder which I already have the 18v lithium ion batteries for. I feel like grinding down welds or cutting through thick metal would eat through a full charge in no time. Am I rong?
After googling it seems like Metabo makes a good grinder. For the occasional hobby fabrication, cutting bolts, and sharpening mower blades is it worth paying a little more than another home depot grade tool?
Also, I have always bought 4 or 4 1/2" grinders... Are the pros of having a 6" grinder relevant for occasional use or do I just have a higher risk of separating one of my digits from my hand?
