  • Patent number: 6578267
    Abstract: A portable, hand held exhaust pipe cutter having an air motor to drive a cutting wheel arranged parallel to a drive shaft of the air motor by an angle head gearing device. The cutter makes straight cross-sectional cuts through cylinders by using a feed lever pivotally attached to the air motor that engages the cylinders to be cut and guides them into engagement with the cutting wheel. The feed lever on an opposing end includes a handle that extends along the air motor so that a user can grip both the control lever of the air motor and the handle of the feed lever simultaneously with a single hand.
