Abstract
A powered cutting tool for cutting tubular or cylindrical workpieces such as pipe is described. The cutting tool includes a base, an electric motor, a collection of rollers, a frame, a feedscrew, an auto cut wheel system, and a handle for rotating the feedscrew and adjusting the position of the auto cut wheel system relative to the rollers. In certain versions, the cutting tool includes torque-limiting provisions, to limit the amount of torque applied to the feedscrew. In certain versions, the cutting tool includes rollers and press wheels featuring non-metal outer surfaces.
Claims13
A powered cutting tool comprising:
- a base;
- an electric motor;
- a plurality of rollers rotatably supported on the base, at least one of which is rotatably powered by the motor;
- a frame extending from the base, the frame defining a threaded receiving region;
- height adjustment provisions enabling the height of the frame relative to the base, to be selectively adjusted;
- a feedscrew defining a first end and a second end, the feedscrew including a threaded region extending at least partially between the first end and the second end, the threaded region of the feedscrew threadedly engaged with the threaded receiving region of the frame;
- a handle engaged at the first end of the feedscrew;
- a cutting wheel engaged at the second end of the feedscrew;
- at least one press wheel attached to the second end of the feedscrew;
- a latch assembly, the latch assembly including a latch base secured to the frame, and a selectively positionable member movably mounted with the latch base, the member defining an engagement end;
- wherein the member is positionable between an engaged position in which the engagement end of the member is in contact with and engaged with the feedscrew, and a disengaged position in which the engagement end of the member is free from contact with the feedscrew;
- wherein upon rotation of the handle and the feedscrew, the distance between the cutting wheel and the plurality of rollers is selectively adjusted.
A powered cutting tool comprising:
- a base;
- an electric motor operable at different motor speeds;
- an adjustable speed switch for selecting different motor speeds;
- a plurality of rollers including a support roller, the plurality of rollers rotatably supported on the base, at least one of which is rotatably powered by the motor;
- a frame extending from the base, the frame defining a threaded receiving region;
- a feedscrew defining a first end and a second end, the feedscrew including a threaded region extending at least partially between the first end and the second end, the threaded region of the feedscrew threadedly engaged with the threaded receiving region of the frame;
- a handle engaged at the first end of the feedscrew;
- a cutting wheel system engaged at the second end of the feedscrew, the cutting wheel system including a cutting wheel and a press wheel, the press wheel attached to the second end of the feedscrew;
- wherein upon rotation of the handle and the feedscrew, the distance between the cutting wheel system and the plurality of rollers is selectively adjusted;
- height adjustment provisions enabling the height of the frame relative to the base, to be selectively adjusted.
