These have a special use for builders, as they permit quick cutout of an area in the middle of a panel (for installation of an electrical box, for example). Just plunge the drill tip into the board and begin to cut the slot, pushing the bit sideways. Always use the largest bit possible, as the stress is high during sideways cutting.
This set of six in a wood box includes five sizes plus a 1/2" countersink.
