Abstract
A nut cutter tool includes a cutter head rotatably driven by a driver. The cutter head may be detachable from the driver for sharpening or replacement of the cutter head. A chip guard may be attached to the tool for catching falling chips and debris. Also a locking mechanism may be provided for releasably locking the tool onto an externally threaded member on which the nut to be cut is threaded to hold the tool in axial alignment with the nut during the nut cutting operation.
Claims37
A nut cutter tool comprising a cutter head, a rotatable driver drivingly connectable to said cutter head for rotating said cutter head during rotation of said driver, said cutter head being detachable from said driver for sharpening or replacement of said cutter head, a tubular body member surrounding said driver, said body member having an outboard end extending axially beyond an end of said driver to which said cutter head is drivingly connectable, said outboard end of said body member providing a chamber adjacent said end of said driver in which said cutter head is removably received, and a removable cap on said outboard end of said body member, said cap having an axial opening through which cutting blades on said cutter head extend during cutting of a nut while preventing said cutter head from being removed from said chamber without first removing said cap from said body member, said cap being threadedly connectable to said outboard end of said body member.
The tool of claims wherein said chip guard is axially movable along said tool.
A nut cutter tool comprising a cutter head, a rotatable driver drivingly connectable to said cutter head for rotating said cutter head during rotation of said driver, said cutter head being detachable from said driver for sharpening or replacement of said cutter head, a tubular body member surrounding said driver, said body member having an outboard end extending axially beyond an end of said driver to which said cutter head is drivingly connectable, said outboard end of said body member providing a chamber adjacent said end of said driver in which said cutter head is removably received, said driver and said cutter head being rotatable and axially movable relative to said body member, a spring for biasing said cutter head and said driver axially inwardly relative to said body member so that cutting blades on said cutter head do not protrude axially outwardly beyond said body member unless an axial outward force is applied to said driver while said body member is restrained against axial outward movement, and a second spring between said cutter head and said driver enabling said cutter head to rebound back away from a nut being cut by cutting blades on said cutter head if too much cutting force is applied to the nut by said cutting blades.
A nut cutter tool comprising a cutter head, a rotatable driver drivingly connectable to said cutter head for rotating said cutter head during rotation of said driver, said cutter head being detachable from said driver for sharpening or replacement of said cutter head, and a guide on said tool that fits closely over an externally threaded member on which a nut to be cut is threaded to guide and keep said cutter head aligned with the threaded member during a nut cutting operation.
A nut cutter tool comprising a cutter head, a rotatable driver drivingly connectable to said cutter head for rotating said cutter head during rotation of said driver, said cutter head being detachable from said driver for sharpening or replacement of said cutter head, and a chip guard on said tool for catching falling chips and debris during a nut cutting operation, said chip guard being press fitted onto said tool.
A nut cutter tool comprising a cutter head, a rotatable driver drivingly connectable to said cutter head for rotating said cutter head during rotation of said driver, said cutter head being detachable from said driver for sharpening or replacement of said cutter head, and a locking mechanism for releasably locking said tool onto an externally threaded member on which a nut to be cut is threaded to hold the tool in axial alignment with the threaded member during cutting of the nut.
A nut cutter tool comprising a cutter head, a rotatable driver drivingly connected to said cutter head, and a chip guard on said tool for catching falling chips and debris during a nut cutting operation, said chip guard having a press fit on said tool.
A nut cutter tool comprising a cutter head, a rotatable driver drivingly connected to said cutter head, and a locking mechanism for releasably locking said tool onto an externally threaded member on which a nut to be cut is threaded to hold the tool in axial alignment with the nut during a nut cutting operation, said locking mechanism having a threaded connection with said driver, whereby when said locking mechanism is locked onto the externally threaded member and said driver is rotated, said threaded connection will cause said driver and said cutter head to move axially relative to said locking mechanism to provide a mechanical advantage during the nut cutting operation, the externally threaded member being tubular, and said locking mechanism comprising an external cone shaped member that internally grips an end of the externally threaded member when moved into engagement therewith.
A nut cutter tool comprising a cutter head, a rotatable driver drivingly connected to said cutter head, and a locking mechanism for releasably locking said tool onto an externally threaded member on which a nut to be cut is threaded to hold the tool in axial alignment with the nut during a nut cutting operation, said locking mechanism having a threaded connection with said driver, whereby when said locking mechanism is locked onto the externally threaded member and said driver is rotated, said threaded connection will cause said driver and said cutter head to move axially relative to said locking mechanism to provide a mechanical advantage during the nut cutting operation, said locking mechanism comprising a female threaded clamp-on piece having internal threads that thread onto a threaded end of the externally threaded member.
A nut cutter tool comprising a cutter head, a rotatable driver drivingly connected to said cutter head, and a locking mechanism for releasably locking said tool onto an externally threaded member on which a nut to be cut is threaded to hold the tool in axial alignment with the nut during a nut cutting operation, said locking mechanism having a threaded connection with said driver, whereby when said locking mechanism is locked onto the externally threaded member and said driver is rotated, said threaded connection will cause said driver and said cutter head to move axially relative to said locking mechanism to provide a mechanical advantage during the nut cutting operation, said locking mechanism having a socket accessible through an inboard end of said driver for engagement by a wrench extension for rotating said locking mechanism relative to said driver.
A nut cutter tool comprising a cutter head, a rotatable driver drivingly connected to said cutter head, and a chip guard on said tool for catching falling chips during cutting of a nut threaded onto an externally threaded member extending downwardly below a support member, said chip guard being spring loaded by a spring urging said chip guard in a direction axially outwardly relative to said cutter head and said driver so that cutter blades on said cutter head are not exposed when said tool is not in use, and said chip guard having a continuous outer lip that is maintained by the spring in full contact with the support member completely surrounding the nut during the nut cutting operation to provide a completely enclosed reservoir surrounding the nut for collecting all of the chips that are produced during the nut cutting operation.
