An angle attachment of 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.
