Hole cutter for plastic tubing

A hole cutter for plastic tubing comprising:

• a pair of opposed members pivotally joined at one end thereof by an integral pivot and facing each other at the opposite free ends thereof, said opposed members being pivotally adjustable to an open and closed position,
• means between said opposed members limiting the separation between the free ends thereof in the open position, said limiting means being spaced between said integral pivot and said free ends and comprising aligned projections extending toward each other from each of said opposed members, said limiting means permitting adjustment of said opposed members between open and closed position but restricting separation beyond said open position,
• the free ends of said opposed members having complimentary shaped recesses therein at the extremity of the free ends thereof adapted in closed position to form a tube-shaped opening for gripping a tube therebetween, and
• a hollow cylindrical cutting blade rotatably mounted on the free end of one of said opposed members, the cutting edge of said blade extending through said free end into the tube-shaped opening, said blade adapted upon rotation to cut a hole in tube gripped in said cutter.
