Abstract:

A drill attachment for smoothing the edges and corners of a concrete slab is disclosed. The drill attachment includes a shaft that is secured or chucked into an electric drill. Pluralities of troweling blades extend from the central shaft and are secured at their ends to maintain their position and orientation. The blades are secured to the trowel at variable or fixed angles that are changeable to suit the finishing need of the operator. In operation the drill attachment is used to smooth the ends and corners of a foundation where larger smoothing trowel machines have difficulty reaching. The power trowel is field installed and removed when needed for use, cleaning and storage. The drill attachment has an independently spinning blade cover extends over the ends of the blades to prevent damage to a wall or other surface when the trowel is in use.
