I felt like biting the bullet and getting a good set of brad-point drill bits. I figured I would just see what people recommended and order a set. Unfortunately, NOTHING IS EVER SIMPLE.
It looks like W.L. Fuller makes highly regarded drill bits. Fine. I believe it. But if you want to buy a set, they come in two lengths (long and short, obviously) and different shank diameters. Now I'm paralyzed, trying to figure out which to get.
When it comes to machining, short drills are usually better, for more than one reasons. I am wondering if the same is true of wood drills. Short drills tend to be more stable and so on, but on the other hand...short. I can't recall ever drilling a hole more over 2" deep in wood, but maybe the need will become obvious right after I order a set.
As for shanks, it appears you can get them in 3/8" diameter. This would look funny on a skinny drill bit, but on the other hand, one would think the bits would be less likely to spin in the chuck because you can apply more torque to a big diameter without slipping.
What's the answer, if you want a serious set for all-around wood use? I don't have a particular job in mind. I would just like to know that when I need to drill a hole in wood, I will USUALLY have the right tool on hand.
