Harbor Freight - Gems and Junk

Anyone use their electrical knockout cutters? I need to cut one 1 inch hole to move a sub panel inside. @ $29 (minus the 20%) I get the whole set versus just one name brand cutter for that price.

If it's a local store I might try 'em provided the online reviews were positive. No good, take 'em back.

FWIW, I decided against their Forstner bit set just by what the web site reviews said.

IMO, Use some cutting fluid if you go with a bi-met hole saw.
