Hi folks,
Well, I was in the process of installing my wood vise when I decided to do this. I used 3/8-16 x 5" Fh machine screws with nuts to install my vise. As you can see in the pictures what I did. I used a 45 degree chamfering bit to countersink the screws. Would you believe that the bearing on the bit was exactly 3/8th of an inch thick. Same size as the holes. All I had to do was get the bit right over the hole, turn on the router and cut away. It made a nice clean countersink hole....Nice!
