    摘要： A boring head for reaming a pre-drilled hole in raise boring or for similar earth cutting operations comprising a plurality of roller cutters (13-22). For purposes of extending the radius of the boring head (10) in operation or decreasing its dimensions during transport one or several extension elements (36, 37) are provided for detachable attachment to the boring head (10) by means of a wedge connection (42).

    摘要： A rotary insert bit tool holder has a peripheral recess in which the bit is clamped with a wedge and a lock screw directed inwardly of the recess forcing the wedge frictionally apart against one side of the recess. A lifting jack engages under the bit and is adjusted outwardly of the recess by a screw threaded through the jack and against the bottom of the recess.

    摘要： A flat and centrally apertured wafer-like insert of cutting material provides a plurality of angularly spaced available cutting tips and is located edgewise against angularly related abutments upstanding from the inner edge of a supporting surface or platform against which the insert is clamped in the final seating in a conical end of the insert aperture of the mating conical head of a screw extending through the insert aperture and threading into a hole in the platform. The insert aperture is larger than the screw shank, and the outer end of the screw hole axis is inclined relative to the axis of the insert cone at a small angle and toward the abutment corner. As a result and in the final tightening of the screw after edgewise camming of the insert against said abutments, the screw shank bends laterally to allow seating of the coned screw head in the insert recess around substantially the full peripheries of the mating cones.

    摘要： A rotary cutting tool having throwaway tool bits disposed in a slot in the tool head. A semicircular clamp is mounted in a groove in the slot wall and is tightened against the bit by a screw. Slide plates are disposed in the slot and are radially adjustable by a cam screw to provide adjustable seating for the bits.

    摘要： THE INVENTION PROVIDES A CUTTING TOOL HEAD IN WHICH REMOVABLE CUTTING INSERTS (PARTICULARLY BLADES) CAN BE POSITIONED WITH SUFFICIENT ACCURACY TO PROVIDE FINE QUALITY SURFACE FINISHES WITHOUT THE NEED FOR SPECIAL GRINDING OPERATIONS. THE NEW CUTTING TOOL HEAD COMPRISES A BODY WHICH IS SLOTTED TO RECEIVE THE REMOVABLE CUTTING INSERT, AND THE CUTTING TOOL HEAD COMPRISES A FIRST MEMBER AND A SECOND MEMBER, THE FIRST MEMBER BEING SEATED IN THE SLOT AND BEING SCREW THREADED, THE SECOND MEMBER BEING COMPLEMENTARILY SCREW THREADED, THE SECOND MEMBER BEING FIRST MEMBER AND HAVING A BEARING SURFACE TO ABUT A LATERAL EDGE OF THE CUTTING INSERT, WHEREBY RELATIVE SCREW MOTION OF THE FIRST MEMBER AND THE SECOND MEMBER ADJUSTS THE PROJECTION OF THE CUTTING INSERT FROM THE BODY.
