I already have a RotoZip that I can use for "some" cutting but it takes thir special 3.5" wheels so they get expensive.
I compared the 4.5 and 7 inch grinders and the 4.5 weighs 10.5 lbs and the 7 weighs 11.5. There is only a one pound difference. The performance looks the same in terms of the motor amps and rpms but the COST is nearly twice as much. I am thinking the 4.5 will fit my needs.
