Well I could not find my original posting with my question on carbide bits so I thought I would start this one and thank all who gave me a reply about which bits to buy. I went with the Freud carbide bits and they work like a charm in the material I am cutting. I finally was able to start making some of these billiardball clocks which I am going to try selling at a craft show this weekend. Thanks again for the replys and for looking. Have a great day.
