An unusual expansive bit made by Bruno Tools out of Beverly Hills. As it says on Martin J. Donnelly Antique Tools, "When one thinks of Beverly Hills, California, one thinks immediately of auger bits."
Bruno Tools advertised frequently in Popular Science in the 1940's and it seems from their ads that this tool was their sole product. Apparently, not enough sales to carry them far into the post-war world.
