ABSTRACT:
A motorized hand torch with an improved brake mechanism is provided. The brake mechanism includes a brake lever which is manually actuable to either a locked or an unlocked position. The brake lever, in turn, has a cam portion thereon which moves a pivotally mounted leaf spring so as to selectively lock a mounting bracket supporting a drive wheel whereby straight line cutting may be accomplished. A circle cutting attachment is also provided which includes a means for preventing locking the mounting bracket.
