Method of use for debris removal system for power tool

A method of using a hand-held power tool having a debris removal attachment, the method comprising:

• providing a hand-held power tool comprising:
• a motor disposed in a motor housing;
• an output shaft coupled to the motor;
• and
• providing a debris removal attachment comprising:
• an extension shaft having a first end and a second end, the second end configured to couple to a tool bit;
• a first impeller coupled to the extension shaft, the rotation of which is configured to generate a pressure differential sufficient to draw debris into the debris removal system;
• a housing substantially disposed about the first impeller;
• a second impeller coupled to the extension shaft;
• and
• a substantially planar member separating the first impeller and the second impeller;
• and
• detachably coupling the first end of the extension shaft to the output shaft.

A method of using a debris removal attachment for a hand-held power tool, the method comprising:

• providing an extension shaft, the extension shaft having a first end and a second end, the first end configured to couple to an output shaft, and the second end configured to couple to a tool bit;
• coupling a first impeller to the extension shaft;
• providing a housing adjacent the first impeller;
• providing a labyrinth seal in a pathway between an exterior of the housing and an interface of the extension shaft and the output shaft, the labyrinth seal having a plurality of spaced apart annular projections provided for disrupting the pathway;
• selectively coupling the first end of the extension shaft to an output shaft;
• and
• rotating the first impeller to generate a pressure differential sufficient to draw debris into the housing.
