Abstract
A hole saw blade comprises a substantially cylindrical body with a pair of sides extending substantially concentric to each other. The sides have an inner surface and an outer surface. A cutting edge extends from an end of the body. A plurality of teeth defines the cutting edge. The teeth are arranged in an alternating pattern in which a first tooth extends inwardly of a cylinder containing the inner surface a first inner distance. A second tooth is adjacent to the first tooth extends outwardly of a cylinder containing the outer surface a second outer distance. A third tooth is located adjacent the second tooth on an opposite side of the first tooth and that extends inwardly of the cylinder containing the inner surface a third inner distance greater than the first inner distance.

A hole saw comprising:
- a substantially cylindrical body having a pair of sides extending substantially concentric to each other, the sides having an inner surface and an outer surface;
- a cutting edge extending from an end of the body;
- a plurality of teeth defining the cutting edge, the teeth are arranged in an alternating pattern where a first tooth extends inwardly of a cylinder containing the inner surface a first inner distance;
- a second tooth adjacent to the first tooth extending outwardly of a cylinder containing the outer surface a second outer distance;
- a third tooth located adjacent the second tooth on an opposite side of the first tooth extending inwardly of the cylinder containing the inner surface a third inner distance greater than the first inner distance;
- a fourth tooth located adjacent the third tooth on an opposite side of the second tooth extending outwardly of the cylinder containing the outer surface a fourth outer distance substantially equal to the second outer distance;
- and
- a fifth tooth located on a side of the fourth tooth opposite the third tooth extending inwardly of the cylinder containing the inner surface a fifth inner distance greater than the third inner distance.
A hole saw comprising:
- a body having a pair of sides, the sides having a first surface and an opposite second surface;
- a cutting edge extending from an end of the body;
- a plurality of teeth arranged in an alternating pattern where a first tooth extends to one side of the first surface a first distance;
- a second tooth adjacent to the first tooth extending in an opposite direction from the second surface a second distance;
- a third tooth located adjacent the second tooth on an opposite side of the first tooth extending from the first surface a third distance greater than the first distance;
- a fourth tooth located adjacent the third tooth on an opposite side of the second tooth extending from the second surface a fourth distance substantially equal to the second distance;
- and
- a fifth tooth located on a side of the fourth tooth opposite the third tooth and that extends from the first surface a fifth distance greater than the third distance.
A hole saw comprising:
- a substantially cylindrical body defining a center axis of rotation, having an inner surface and an outer surface;
- a plurality of teeth defining a cutting edge, the plurality of teeth arranged in a-pattern including a first group of teeth oriented at angles toward the center axis of rotation and a second group of teeth oriented at an angle away from the center axis of rotation intermixed with the first group;
- where the teeth angled away from the center axis of rotation are each oriented at substantially the same angle;
- and
- where the teeth angled toward the center axis of rotation are oriented with angles of increasing magnitude as compared to a prior tooth of the first group.
