摘要： A cutting tool includes a generally cylindrical body, a plurality of cutting teeth formed on the generally cylindrical body, a plurality of non-cutting protrusions formed on the generally cylindrical body, and a plurality of gullets formed on the generally cylindrical body. Each gullet is formed between one of the plurality of cutting teeth and one of the plurality of non-cutting protrusions. Each gullet has a base and a gullet depth measured from the base to a tip of a corresponding cutting tooth. Each non-cutting protrusion is located approximately halfway between the tips of two adjacent cutting teeth and has a height that is at most about 75% of the gullet depth.

摘要： A hole saw includes a cylindrical body having a sidewall with a first end and a second end opposite the first end. The cylindrical body includes a gullet formed in the sidewall between a leading surface, a trailing surface, and a bottom surface of the sidewall. The gullet defines a central longitudinal axis extending between the first and second ends of the sidewall that is obliquely oriented relative to a rotational axis of the hole saw such that the gullet is angled from the first end to the bottom surface in a direction toward a cutting direction of the hole saw. The gullet has a dimension measured parallel to the rotational axis between the first end of the sidewall and the bottom surface of the gullet that is greater than 1.5 inches. The hole saw includes a cutting tooth coupled to the first end of the sidewall adjacent the gullet.

摘要： A hole saw includes a substantially cylindrical body defining a cutting end and an axis of rotation. The hole saw also includes first and second apertures formed through the body and spaced from the cutting end such that a portion of the body extends between the cutting end and both the first and second apertures. The first and second apertures are both configured to receive a tool for removing work piece plugs from within the cylindrical body. The first aperture is axially spaced from the cutting end a first distance. The second aperture is axially spaced from the cutting end a second distance that is greater than the first distance. The first aperture and the second aperture are separated by a portion of the body.

摘要： A hole saw includes a cylindrical body disposed along an axis of rotation with a side wall extending axially from a cap end to a cutting end. The cutting end includes a plurality of cutting teeth. The hole saw also includes a cap coupled to the cap end of the cylindrical body. The side wall defines an elongated aperture configured to receive a tool for removing work piece plugs from within the cylindrical body. The elongated aperture has a first slot portion adjacent the cutting edge. The first slot portion is oriented perpendicular to the axis of rotation. The elongated aperture also has a second slot portion connected to the first slot portion and extending from the first slot portion toward the cap end. The second slot portion is oriented at an oblique angle relative to the axis of rotation.

摘要： A hole saw includes a cylindrical body disposed along an axis of rotation with a side wall extending axially from a cap end to a cutting end. The cutting end includes a plurality of cutting teeth. A cap includes a rim portion seated on the cap end and an axially extending portion extending into the cylindrical body from the cap end. The side wall defines an aperture including a first slot portion and a second slot portion disposed closer to the cap end than the first slot portion. A wall of the second slot portion nearest the cap end is between approximately 0.010 inches and approximately 0.120 inches axially offset from the axially extending portion of the cap.
