Abstract: The invention relates to a chisel holder for a ground processing machine, in particular a road miller, comprising a supporting member to which a plug-in attachment is indirectly or directly connected at a plug-in attachment end. The plug-in attachment has at least one convex contact surface and a pressure surface. In order to deflect the processing forces in such a chisel holder in an optimized manner with respect to the load conditions, the plug-in attachment has two convex contact surfaces that are located at a distance from each other.

Abstract: An excavation cutting tool holder retention system. The cutting tool holder retention system includes a cutting tool holder having a holder engagement surface and a support block having a tool holder bore into which the cutting tool holder is inserted. A pin having a pin engagement surface is movably mounted to the support block such that the pin engagement surface may be moved to engage the holder engagement surface. At least one of the holder and pin engagement surfaces defines an inclined surface such that when the pin engagement surface is moved to engage the holder engagement surface, the shank portion of the cutting tool holder will be drawn into the tool holder bore. In the preferred embodiment, at least one of the shank portion of the cutting tool holder and tool holder bore is tapered such that the shank portion of the cutting tool holder will be drawn and wedged into the tool holder bore of the support block when the pin engagement surface is moved to engage the holder engagement surface.

Abstract: A fixed cutter rock bit includes a cutting head having a plurality of spiral blades and bosses into which extend cutter insert mounting holes. Cutter inserts with cutting tips and barrels protrude outward from the mounting holes at an angle to the general direction of rotation of the cutting head. Each cutter insert has a cutting tip, a barrel, a dowel recess, an end flange, and a cutter axis extending from the cutting tip through an end flange. Dowel pin holes extend into the blades transverse to the cutter mounting holes, the dowel pin holes adapted to receive and position dowel pins transverse to the cutter inserts such that the cutter inserts are free to rotate about their respective cutter insert axes.

Abstract: A cutting assembly is configured to be coupled to a drum that is rotatable about an axis. The cutting assembly includes a block having a leading surface and an inner surface. The inner surface forms a block bore extending along an axis through the leading surface and at least partially through the block. The cutting assembly also includes a sleeve having a sleeve shank with an outer surface, a flange, and a sleeve bore extending through the flange and at least partially through the sleeve shank. During installation of the sleeve to the block, an interface between the outer surface of the sleeve shank and the inner surface of the block bore transitions from an interference fit to a clearance fit.
