Hole saw

A saw blade comprising:

• a body having a pair of sides, the sides having a first surface and an opposite second surface;
• a cutting edge extends from an end of the body;
• a plurality of teeth being 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 extends 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 and that extends 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 and that extends from the second surface a fourth distance substantially equal to the second distance;
• and
• a 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 having a pair of sides extending substantially concentric to each other, the sides having 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;
• a tooth extends inwardly of the inner surface a first inner distance;
• and
• another tooth that extends inwardly of the inner surface a second inner distance greater than the first inner distance.
