Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract translation: 一种切削工具包括一个大致圆柱形的主体，多个切割齿形成在大致圆柱形的主体上，多个非切割凸起形成在大致圆柱形的主体上，以及多个凹槽，形成在大致圆筒体上。 每个齿槽形成在多个切割齿中的一个和多个非切割突起中的一个之间。 每个食道具有从基部到相应的切割齿的尖端测量的基部和沟槽深度。 每个非切割突起位于两个相邻切割齿的尖端之间的大约一半处，并且具有至多约95％的齿槽深度的高度。

Abstract: 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.
