Grinder opinions? The guy I work with only buys these $100 DeWalts. They are strong but they get hot quick so he keeps 3 in use a sets them in front of a fan and rotates them so they don't blow up.

This seems wrong. Are there grinders in this price range that can have long duty cycle? I don't insist on 13amps but maybe that is what it takes for them to hold up?

Thanks,

Mike
