Robert Tull-ABC Bird Toys Inc. They truly are state of the art bits. But I'm shure the sales staff at Skarie told you that. We were told, that if they were manufactured in the US, these bits would cost upwards of $80.00 or so. Oh, by the way, I posted that we usually cut about 3,000 parts before we change to new. Please keep in mind that our parts are not very big(about 4" in diameter). Just thought you should know.
