This isn’t the best set of jobber’s drills that I’ve ever owned, but it’s pretty good for the money. The flutes are well formed and the edges are sharp. The web is a little thick and the point is not split, but th8iat is to be expected at this price. The drill index is satisfactory. So far, I’m happy.
