Cutting edge forming the edge of the land.

body

flute

Groove in the body of the bit that removes debris from the hole while drilling.

shank

solid center auger bit

Bit made up of a central shank encircled by a twist; it is very durable and especially designed for making deep holes.

twist

Spiral protrusion around the bit’s shank; it removes debris from the hole being drilled.

spur

Lip that covers the outline of the hole and removes debris, which is then pushed to the twist and disposed of.
