A guide for setting the depth of cut of a cutting tool, or other hand-held power tool, which automatically locks into a desired position to set the depth of a cut without requiring manual operation of a locking knob or similar structure. The depth guide is released from the locked Position by actuation of a release switch. The depth guide includes a depth guide base, a depth guide shaft attached to the depth guide base, and an automatic locking and release mechanism coupled to the depth guide shaft. The automatic locking and release mechanism and depth guide shaft may be mounted in a handle of the hand-held power tool, such as a detachable handle, for mounting the depth guide to the tool. A dust collector is provided for removing cutting debris which may accumulate in the base of a depth guide around the point of a cut.

A hand-held power tool, such as a spiral cutting tool, with improved operator control and visibility. The power tool includes a motor contained in 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 the cutting tool motor. The trigger switch is mounted in the detachable handle in a position such that the switch is operated by the little finger and ring finger 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 to 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 cutting debris therefrom to further improve operator visibility.

Hand-held power tool

An angle attachment for a hand-held power tool, such as a spiral cutting tool, includes an angle attachment housing having an open first end adapted to be attached to the motor housing of the power tool. An alignment bearing is mounted in the angle attachment housing and adapted to receive and support a first shaft having a first shaft gear mounted thereon. An attachment shaft is mounted in the angle attachment housing at an angle, e.g., a right angle, to the first shaft. The attachment shaft includes an attachment shaft gear mounted thereon which is engaged with the first shaft gear. One or more attachment shaft bearings are mounted in the angle attachment housing to support the attachment shaft for rotational movement thereof. The first shaft is coupled to a motor shaft of the power tool before the angle attachment housing is attached to the power tool motor housing. Rotation of the first shaft by the power tool motor causes rotation of attachments attached to the attachment shaft mounted at an angle to the first shaft by means of the gear mechanism formed by the engaged first shaft gear and attachment shaft gear.

A detachable battery pack is connectable to hand-held power tools, such as spiral cutting tools, in which cuts are made by positioning the axis of the cutting tool motor housing perpendicular to a workpiece surface, and moving a cutting tool bit through the workpiece in a direction perpendicular to the axis of the bit to remove material from the workpiece. The battery pack allows the cutting tool to be utilized without an electric cord and without the need of a power source near-by, thereby increasing maneuverability, safety, and range of use. The battery pack is connected to the motor housing of the power tool by being received by a receptacle. The receptacle is preferably formed to include one or more storage compartments therein, accessible through apertures in the receptacle for storage of additional cutting tool bits. A sliding door on the receptacle may be provided to allow access to the storage compartments, and to close the compartments to secure items stored therein during operation of the cutting tool. The receptacle extends outwardly beyond the motor housing over a handle so that the weight of the battery pack is centered over the handle.
