I posted recently on drill guides for drilling 3/4” dog holes in a 2 1/2” ash workbench top. Thanks to all who replied. Due to the suggestions I received, I think I can manage to make a decent drill guide, but the responses raised other questions about proper drill bits.
I went to The Home Depot yesterday and was happy to find an Irwin auger bit at 3/4” that the salesperson told me would work in a drill press (For making my drill guide) and in a hand held drill. Ah! Bought it. It has parallel sides of good length to work in a drill guide—or so I thought.
Then I got home and read a post from one man who said these bits were not really good for this task—wood chip clogs, burning, hard on the drill, etc. It was suggested to use a brad point bit instead. I checked various Web sites and the only 3/4” brad point bit I could find was a HSS (HHS?) bit from Rockler. Every person who had posted a “review” of these bits on their Web site indicated that they drilled holes larger than the nominal size. One gent stated that he drilled a hole for a dowel and when he inserted the dowel it fell out of the hole because the hole was too large. I certainly do not want this to be happening with my dogs!
So there is my dilemma. Comments?
