Abstract
A tool for installing a turn vane within air conditioning duct work includes an octagonal shaft having a cutting head at an end thereof. The cutting head includes a pair of spaced parallel outer blades each having a downwardly angled cutting surface. Disposed between the outer blades is an oppositely facing inner blade likewise having a downwardly sloping cutting surface. A second embodiment includes a shaft adapted to be used with an air driven hammer. When force is applied to the shaft with either a conventional or air driven hammer, oppositely directed, severed portions are created on the turn vane thereby securing it to a turn vane rail.
