Abstract:
A portable powered hand-held tubing cutter which comprises:a portable frame comprising a first portion enclosing and retaining a cutting head and an elongated second portion extending from said first portion and forming a handle;a motor mounted within said frame for rotating a cutting head;a battery having an electrical connection with said motor to power said motor;said cutting head being within said frame and rotatable by said motor, having a central aperture for receiving a length of tubing disposed coaxially of the cutting head, a recess extending radially from said aperture, and cutting means for cutting said tubing disposed in and moveable along said recess and comprising a rotatable cutting blade with a cutting edge capable of being disposed into said aperture;indexing means cooperating with said cutting means for indexing said cutting means along said recess as said cutting head is rotated by said motor;said motor being reversible, such that rotation of said cutting head by said motor in one direction causes said indexing means to move said cutting blade radially inwardly of said cutting head and upon reversal rotation of said cutting head by said motor in an opposite direction causes said indexing means to move said cutting blade radially outwardly of said cutting head; andwhereby as said motor rotates said cutting head and said cutting means moves inwardly along said recess by said indexing means, said cutting blade rotates around said tubing, said cutting edge cuts into said tubing and each rotation of said cutting head causes said cutting means to move further inwardly and said cutting blade to cut deeper into said tubing.
