Just for the sake of argument, lets say I want to make my own workbench top 4" thick, with round dog holes. What are my options?
My first thought was a 3/4 Forster bit but all the ones I can find dont have a long enough shank. My next thought was a router bit to do a plunge cut but short lenghts are also the issue here plus I think I'd have to use 2 different length bits. Not sure off the top of my head, but I dont think 4" plunge travel is do-able even if I could find a long bit.
The only thing I've spotted is a 3/4" HSS Lipped Brad-Point bit from LV - 6" with 3" of fluting. That looks like it would work, but thought I'd troll for any other suggestions.
