Power tool

摘要

This invention relates to a power tool ( 1 ) including an operative element ( 4 ) for treating a work piece. The power tool ( 1 ) defines an air passageway and includes propelling means ( 20 ) operative to induce air to flow through the passageway. The passageway direct the induced air over the power tool's motor ( 14 ) to cool the motor ( 14 ). The air is exhausted from the tool ( 1 ) by exhaust means onto the operative element ( 4 ) and a worked face of the work piece. This cools the operative clement ( 4 ) which prolongs its working life. Furthermore, the exhausted air facilitates removal of swarf from the worked face.
