  • Patent number: 6609302
    Abstract: A bolt cutting tool comprises a bolt engaging portion and a cutting blade. The bolt engaging portion has at least one bolt-receiving bore, which is adapted for receiving a portion of a bolt to be cut. The cutting blade is rotatably connected to the tool generally adjacent the bolt engaging portion. The cutting blade has a cutting surface with an arcuate peripheral cutting edge. The cutting blade is adapted for rotation relative to the bolt-receiving bore from a pre-cut starting position toward a post-cut finishing position. The blade is adapted to rotate in a manner so that the arcuate peripheral cutting edge of the blade cuts the bolt as the cutting blade is rotated toward the post-cut finishing position. The blade is configured so that an angle of incidence between the cutting surface of the blade and a center axis of the bolt-receiving bore is less than 15 degrees when the blade is in its pre-cut starting position.
