HAND-HELD POWER TOOL

摘要

A hand-held power tool, such as a spiral cutting tool, with improved operator control and visibility. The power tool includes a motor contained i n a motor housing. The motor may be a variable speed motor controlled by a speed control user interface mounted on the housing. Each time a speed control button is actuated, the motor speed is changed. A display provides the operator of the tool with an indication of the motor speed selected. A detachable handle is provided with a moveable mechanism for easily, quickly, and securely attaching the handle to the housing and removing the handle therefrom with one hand. The detachable handle may include one or more storage compartments formed therein. The detachable handle includes a trigger switch mounted therein for operating th e cutting tool motor. The trigger switch is mounted in the detachable handle i n a position such that the switch is operated by the little finger and ring fing er of an operator's hand. The trigger switch is coupled to a motor controller within the motor housing without use of a direct mechanical connection, so as not to interfere with the easy and quick attachment and detachment of the handle to and from the housing. Operation of the trigger switch is enabled by a multiple-position power switch mounted on the housing. High-output LEDs are mounted in the housing t o direct beams of light toward a workpiece at the point of a cut, to improve workpiece visibility. Air vents are provided for directing a flow of air onto a workpiece being cut to remove curing debris therefrom to further improve operator visibility .
