Abstract: A cone hogger unit has axially juxtaposed cutting elements resembling circular saw blades that stepwise increase in diameter from one axial end of the unit. A cutting element intermediate the axial ends of the unit is integral with a body member that has opposite axially projecting hub-like portions, each extending through cutting elements at its axial side of said one cutting element. Circumferentially spaced screws, parallel to the unit axis and at one distance therefrom, pass through the smaller diameter cutting elements and are threaded into said one cutting element. The larger diameter elements are similarly secured by other screws at a greater distance from the unit axis.

Abstract: An edge machining tool in which two substantially identical tool members are mounted on a work spindle with each tool member having peripheral axial portions extending into notches in the other tool member. The aforementioned axial portions are provided with cutting edges and incline downwardly toward the other tool member so that in cross section the tool members define a "V" shape therebetween. At least one threaded adjusting spindle is provided which is held against axial movement on the work spindle and which engages the tool members with threads of respective hand so that by rotation of the adjusting spindle the tool members can be caused to move toward and away from each other on the axis of the work spindle.
