Description:

"My invention consists in forming the twist of an auger or auger-bit, so that while half circles shall be formed by the twist for the discharge of the shavings, by turning the edge of the twist inward, the cutting-lip of the auger shall receive its shape from the form of the twist, and the outer edge of the twisting shall be a cutting-edge its whole length."
