IF you've ever used cheap bits that come "for free" with a gouge, you'll appreciate the difference with Delta bits. They are made in Austria (for easy identification). They are sharp and hold an edge much better than cheap ones. The square part is particularly strong as the corners seem to be made very strong to hold their edges/points. I sincerely recommend that if you are disappointed with the quality of your cheap beats you buy a set of these. great products.
