  • Patent number: 10668542
    Abstract: An auger bit for cutting holes. The auger bit includes a body made of a first material. The body has a first end, a second end configured to be coupled to a power tool, a flute, and a longitudinal axis extending centrally through the body. The auger bit also includes a cutting tip made of a second material different from the first material. The cutting tip is coupled to the first end of the body. The cutting tip includes a first shoulder having a first spur, a first main cutting edge, and a first side cutting edge. The cutting tip also includes a second shoulder opposite the first shoulder and having a second spur, a second main cutting edge, and a second side cutting edge. The cutting tip further includes a center spur positioned between the first shoulder and the second shoulder and on the longitudinal axis.
