摘要： A viewing window for covering an aperture in a hand-held circular saw includes an optically transmissive member adapted to be coupled with the guard. The member is movable between a closed position, wherein the member substantially covers the aperture, and the open position, wherein the member at least partially uncovers the aperture, to allow the cleaning of the member. A structure is provided for biasing the member to the closed position.

摘要： A leverage accessory for hand-held power drills comprises a lever (10) having a handle (14) at one end and a sharp pointed tip (12) at the other end for plunging (10W) into sheathing (16) attached to the stud or joist (24) being drilled. An instantly repositionable, non-slip contact section (38) connects the lever (10) to the drill body (20) to apply force to the central axis of the drill bit (22). The device can be adapted to existing drill motors (20), and may be made integral to drill motor/lever units (68).
