I always skipped it to save time, but after splitting three pieces of oak baseboard on a job in Boise last month, I started using a 1/16-inch bit first. Anyone have a faster method that still prevents splits?
Read an article a while back that said skipping the pilot hole in hardwoods can actually split the wood, but the crack might be hidden under the surface. They called it a "blind split." Makes you wonder if it weakens the joint over time.
