Abstract
A hand-held power tool includes a housing having a motor provided therein, a cutting accessory coupled to the motor and means for selectively directing a flow of air toward a point of cut of the cutting accessory. The flow of air acts to remove debris at the point of cut to improve visibility of the workpiece.
Claims26
A hand-held power tool comprising:
- a housing having a motor provided therein;
- a cutting accessory coupled to the motor;
- and
- means for selectively directing a flow of air toward and away from a point of cut of the cutting accessory;
- whereby the flow of air acts to remove debris at the point of cut to improve visibility of the workpiece.

A hand-held power tool comprising:
- a housing having a motor provided therein;
- a cutting accessory coupled to the motor;
- and
- means for selectively directing a flow of air toward a point of cut of the cutting accessory:
- whereby the flow of air acts to remove debris at the point of cut to improve visibility of the workpiece;
- wherein the housing comprises at least one vent for directing air toward the point of cut;
- and
- wherein the means for selectively directing a flow of air comprises an air vent cover selectively movable between a first position and a second position.
5 more elements
A hand-held power tool comprising:
- a housing having a motor provided therein;
- a first air vent formed in a first end of the housing;
- and
- an air vent cover provided in the housing and having a first aperture formed therethrough, the air vent cover movable between a first position and a second position;
- wherein the first air vent and the first aperture formed in the air vent cover are aligned in the first position to direct air through the first air vent toward a point of cut when the motor is activated and wherein the first air vent and the first aperture formed in the air vent are not aligned in the second position such that air is not directed through the first air vent toward a point of cut.
2 more elements
A hand-held power tool comprising:
- a motor provided in a housing;
- a first vent provided in the housing and configured to direct a flow of air toward a workpiece when the hand-held power tool is utilized to form cuts in the workpiece;
- a second vent provided in a side of the housing and configured for directing a flow of air in a direction away from the workpiece;
- and
- a vent cover provided in the housing and configured to direct a flow of air through the first vent when the vent cover is in a first position and to restrict the flow of air through the first vent when the vent cover is in a second position.
