Abstract

A tube cutting and installation tool having two semi-circular shaped open cutting heads for cutting different sizes of tube diameter and cut-outs for assisting with the installation of the cut tubes.

Claims

1. A tube cutting and installation tool having a tool body including a handle portion and cutting portion, and the cutting portion includes a first tube open cutting head for cutting tube of a first tube size and a second tube open cutting head for cutting tube of a size different from the first tube size, each first and second tube open cutting head having a semi-circular configuration for receiving the engaging tube of the first tube size and second tube size within an internal circumference, respectively, and a trapezoidal knife blade removably positioned between the first and second tube open cutting heads so that a first blade tip of the trapezoidal knife blade extends into the internal circumference of the first tube open cutting head and a second blade tip of the trapezoidal knife blade extends into the internal circumference of the second tube open cutting head.

2. The tube cutting and installation tool of claim 1, wherein the handle portion of the tool body includes partial semi-circular configuration for engagement with a pipe nut during installation of a tube, and including a U-shaped cutout for engagement with a tab of the engaged pipe nut during installation of a tube.

3. The tube cutting and installation tool of claim 1, wherein the first tube open cutting head has a diameter sized for engagement with a first tube size of 1.25 inches.

4. The tube cutting and installation tool of claim 1, wherein the second tube open cutting head has a diameter sized for engagement with a second tube size of 1.50 inches.

5. The tube cutting and installation tool of claim 3, wherein the second tube open cutting head has a diameter sized for engagement with a second tube size of 1.50 inches.

6. The tube cutting and installation tool of claim 1, wherein the trapezoidal knife blade is removably positioned within the cutting portion by a blade cover plate engaged with the tool body to cover and trap the trapezoidal knife blade within the cutting portion of the tool body using conventional fasteners.

7. The tube cutting and installation tool of claim 1, wherein the cutting portion of the tool body further includes a U-shaped cutout exposing an intermediate section of the trapezoidal knife blade between the first and second blade tips.

8. The tube cutting and installation tool of claim 1, wherein the tool body includes a generally I-beam shaped cross-sectional configuration, and the semi-circular configuration of the first and second tube open cutting heads of the cutting portion of the tool body for receiving the engaging tube of the first tube size and second tube size has a wider cross portion of the I-beam than the opposite cross portion of the I-beam.

9. The tube cutting and installation tool of claim 1, further including a first rotating blade tip cover having an integral pin, where the first rotating blade tip cover is secured to the tool body by a hinged engagement of the integral pin with the tool body adjacent the first tube open cutting head for rotating the blade tip cover into engagement within the semi-circular configuration of the first tube open cutting head to cover the first blade tip of the trapezoidal knife blade when the cutting and installation tool is not cutting a tube.

10. The tube cutting and installation tool of claim 9, further including a second rotating blade tip cover having an integral pin, where the second rotating blade tip cover is secured to the tool body by a hinged engagement of the integral pin with the tool body adjacent the second tube open cutting head for rotating the blade tip cover into engagement within the semi-circular configuration of the second tube open cutting head to cover the second blade tip of the trapezoidal knife blade when the cutting and installation tool is not cutting a tube.
