As thought. I have diamond for the stone but those bits are not offered in the sizes desired. Chalk it up to the cost of making when using that material. That is one of the gripes with these smaller bits. There is a nice price point at certain sizes, these smaller ones are on that rising point.
Ordered some Viking cobalt bits and will see how they do. I haven't had to buy drill bits in a spell so seeing how prices have changed was eye opening. What was paid for USA bits now buys lower grade imports in oxide or bright finish. Had it good with those cobalt and other coated bits in the day. Same with taps, crazy prices.
