HAND-HELD DRILLING TOOL

摘要

A hand-held drilling tool adapted for use by a user to manually drill bores into a selected material, has a base member oriented transversely to a 27 longitudinal axis; and a first blade structure connected to the base member and projecting longitudinally therefrom in a first direction to terminate at a first distal end in a first cutting element. The first blade structure includes a pair of first flat blade sections which are joined together along the longitudinal axis and which extend radially away from the longitudinal axis to terminate in first lateral side edges. A second blade structure is connected to the base member and projects longitudinally therefrom in a second direction opposite the first direction to terminate at a second distal end in a second cutting element. The second blade structure includes a pair of second flat blade sections joined together along the longitudinal axis and which extend radially away from the longitudinal axis to terminate in second lateral side edges. The first and second blade structure are sized and configured such that, when a first one of them is positioned against the selected material, a second of them provides a handle to be grasped by the user for manual rotation thereby to rotatably drive the first one to form a bore in said selected material.
