Abstract
A method of using a hand-held power tool having a debris removal attachment is provided. The method includes providing a hand-held power tool having an output shaft and selectively coupling an extension shaft to the output shaft. The method also includes coupling a first impeller to the extension shaft and providing a housing adjacent the first impeller. The method further includes rotating the first impeller to generate a pressure differential sufficient to draw debris into the housing. The extension shaft has a first end and a second end, the first end configured to couple to the output shaft of the hand-held power tool, and the second end configured to couple to a tool bit.
