A power tool comprising: a housing extending along a tool axis with opposing lateral side surfaces separated by a first distance; a motor contained in the housing and including a stator that is stationary relative to the housing, a rotor that rotates relative to the stator, a motor output shaft rotatably driven by the stator, and a fan coupled to the motor output shaft; an end cap coupled to a rear end portion of the housing; at least one first intake vent (150; 152) disposed axially rearward of the motor, the air intake vents (150; 152) oriented transverse to the axis; and an exhaust vent defined in the housing axially forward of the motor, wherein: the fan is positioned axially forward of the motor proximate the exhaust vent, such that upon actuation of the motor, air flows into the housing through the at least one first intake vent along a first path, over or through the motor, and out of the exhaust vent; characterized in that the end cap has opposed lateral wings; wherein the at least one first intake vent (150; 152) disposed proximate at least one of the lateral wings; and the opposed lateral wings extend radially outward from the side surfaces by a second distance from the X axis that is greater than the first distance, such that the wings are configured to inhibit blockage of the at least one first intake vent (150; 152). a housing extending along a tool axis with opposing lateral side surfaces separated by a first distance; a motor contained in the housing and including a stator that is stationary relative to the housing, a rotor that rotates relative to the stator, a motor output shaft rotatably driven by the stator, and a fan coupled to the motor output shaft; an end cap coupled to a rear end portion of the housing; at least one first intake vent (150; 152) disposed axially rearward of the motor, the air intake vents (150; 152) oriented transverse to the axis; and an exhaust vent defined in the housing axially forward of the motor, wherein: the fan is positioned axially forward of the motor proximate the exhaust vent, such that upon actuation of the motor, air flows into the housing through the at least one first intake vent along a first path, over or through the motor, and out of the exhaust vent; characterized in that the end cap has opposed lateral wings; wherein the at least one first intake vent (150; 152) disposed proximate at least one of the lateral wings; and the opposed lateral wings extend radially outward from the side surfaces by a second distance from the X axis that is greater than the first distance, such that the wings are configured to inhibit blockage of the at least one first intake vent (150; 152). the fan is positioned axially forward of the motor proximate the exhaust vent, such that upon actuation of the motor, air flows into the housing through the at least one first intake vent along a first path, over or through the motor, and out of the exhaust vent; characterized in that the end cap has opposed lateral wings; wherein the at least one first intake vent (150; 152) disposed proximate at least one of the lateral wings; and the opposed lateral wings extend radially outward from the side surfaces by a second distance from the X axis that is greater than the first distance, such that the wings are configured to inhibit blockage of the at least one first intake vent (150; 152).
