Abstract
A hole saw includes a base member configured to secure the hole saw to a drive device and a blade member extending orthogonally from each side of the base member. Each blade member is configured having respective distal ends that flex transversely to a longitudinal cutting direction of the blade member. Responsive to rotational movement of the hole saw via the drive device against a structure, a medial location of each blade member creates an initial respective linear cutting path into the structure, and further movement of the respective blade members into the structure cause the distal ends of the respective blade members to flex transversely to the cutting direction and follow the initial linear cutting path despite the rotational movement of the hole saw relative to the structure to produce a linear cut through the structure.
