A spade bit that wanders when you start, burns the wood instead of cutting it, or produces a ragged hole that won't accept the pipe or rod you're running through it — that's a bit that's done.

The flat blade design clears chips on the up-stroke and keeps the hole clean through the full depth. High-carbon steel holds an edge and doesn't flex under pressure the way cheaper bits do.
