I have a job coming up that will require the purchase of 3 new 4 1/2" angle grinders.
What one's last the longest, best, good torque, etc.
I have a 15 year old Snap-on that kicks ass, but their new one's aren't very good from what I hear.

Brand name ideas please, only quality... I only like to buy a tool once (as much as possible, within reason $$)

thanks
