HD rare earth magnets are free and most power for weight, very flat and stream lined, have mounting holes. >>Rare Earth mags good for many things, including fishing wires thru walls etc. >>highest rated n52 class can lift 1000's x own weight! >>larger mags can be dangerous, pinching hand, breaking fingers if between mag and target >>chip easily, warning against swallowing as pieces can attract in intestines, pinch and kill w/gangrene etc.!!! . Can't imagine overhead liability in home-maid stump grinder!
