Bolt cutting tool

A bolt cutting tool comprising:

• a bolt engaging portion having at least one bolt-receiving bore adapted for receiving a portion of a bolt to be cut;
• and
• a cutting blade connected to the tool generally adjacent the bolt engaging portion, the cutting blade having a cutting surface with an arcuate peripheral cutting edge, the cutting blade being adapted for rotation relative to the bolt-receiving bore from a pre-cut starting position toward a post-cut finishing position in a manner so that the arcuate peripheral cutting edge of the blade cuts the bolt as the cutting blade is rotated, the arcuate peripheral cutting edge having a cut initiating portion adapted for initial engagement with a bolt received in the bolt-receiving bore when the cutting blade is in its pre-cut starting position and a cut finishing portion adapted for engagement with the bolt when the cutting blade is rotated toward its post-cut finishing position, the arcuate peripheral cutting edge having a radius of curvature that increases as the cutting edge extends from its cut initiating portion toward its cut finishing portion;
• wherein the radius of curvature of at least a portion of the arcuate peripheral cutting edge increases at a rate that is greater than a constant rate as the cutting edge extends toward its cut finishing portion.

A bolt cutting tool comprising:

• a bolt engaging portion having at least one bolt-receiving bore with an internally threaded portion adapted for threaded engagement with an externally threaded bolt to be cut, the internally threaded portion of said at least one bolt-receiving bore defining a major inside diameter of the bore and a minor inside diameter of the bore, the major inside diameter being larger than the minor inside diameter;
• a cutting blade rotatably connected to the tool generally adjacent the bolt engaging portion, the cutting blade having a cutting surface with an arcuate peripheral cutting edge, the cutting blade being adapted for rotation relative to the bolt-receiving bore from a pre-cut starting position toward a post-cut finishing position 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 arcuate peripheral cutting edge lying within a plane that is generally perpendicular to an axis of rotation of the cutting blade;
• and
• wherein an end portion of said at least one bolt-receiving bore adjacent to said plane is counterbored to a diameter larger than said minor inside diameter.
