A hole saw having depth of travel indicia includes a hole saw with indica marks formed on an outer diameter thereof. The indica marks are preferably formed in the outer diameter of the hole saw with any suitable process. The indica mark preferably is formed perpendicular to the center axis of the hole saw. The indicia mark could continue around the entire outer diameter or have a set length. The location of each indicia mark is a set dimension from tips of the cutting teeth of the hole saw. A dimension is preferably stamped adjacent each indicia mark to indicate the distance from each indicia mark to the tips of the cutting teeth.
