[El Campo]

Never EVER EVER use a larger wheel (or higher speed) than the grinder is rated for EVER. My dad has a friend who is six feet under the ground from doing that. Typically larger wheels are rated for lower speeds and in the case of my dads friend the overspeed of the smaller grinder caused the blade to disintegrate sending a piece of wheel through the femoral artery killing him in about 3 minutes. As far as grinders go I use Makita with excellent luck after locking up several Dewalts. From the research I did Makita is the only (correct me if I am wrong) company that still makes grinders, etc in the USA (although they are not all made here being Japanese(?) company who makes them in Asia also) I went that route. Have no complaints. It does not vibrate as much as some other grinders I have used as well as it stays cool (something my Dewalt grinders did not do well at all). Got mine in a package that contained the grinder and a bunch of Makita wheels including cutoff disc in a case. Was also very impressed with their wheels.
