Embodiments of the invention are directed to cutting tool assemblies, material-removing machines that include cutting tool assemblies, and methods of use and operation thereof. In some embodiments, the cutting tool assemblies described herein may be used in material-removing machines that may remove target material. For example, the cutting tool assemblies may include one or more superhard working surfaces and/or one or more shields.

The present invention relates to a powder for three-dimensional printing of a cermet or a cemented carbide body. The powder has 30-70 vol % of the particles that are <10 μm in diameter. The present invention also relates to a method of making a cermet or cemented carbide body. The method includes the steps of forming the powder, 3D printing a body using the powder together with a printing binder to form a 3D printed cermet or cemented carbide green body and subsequently sintering the green body to form a cermet or cemented carbide body.

A cutter bit for a work tool on a machine includes a leading end, conical-shaped tip portion, a rearward, frustoconical-shaped tip portion extending axially rearwardly from the leading end, conical-shaped tip portion, an annular ledge extending radially outwardly from a trailing edge of the rearward, frustoconical-shaped tip portion, a frustoconical-shaped body portion extending axially rearwardly from an outer circumferential edge of the annular ledge, a cylindrical collar portion extending axially rearwardly from a trailing edge of the frustoconical-shaped body portion, and a trailing end, cylindrical-shaped shank portion extending axially rearwardly from the cylindrical collar portion. The cutter bit may also include a plurality of circumferentially-spaced ribs projecting radially outwardly from an outer peripheral surface of at least one of the leading end, conical-shaped tip portion, the rearward, frustoconical-shaped tip portion, or the frustoconical-shaped body portion.

A highly wear-resistant chisel tip body comprising a material that includes diamond particles or monocrystalline diamond structures, in particular a PCD, CVD or NPD material, with a cutting top and a mounting bottom opposite said cutting top, via which the chisel tip body is attachable to a support body. The invention further relates to a milling chisel, a milling drum, as well as a ground milling machine having such a chisel tip body.

A rotatable bit cartridge that can be inserted and removed from permanently mounted cutter bodies, bit holders, and/or picks and are used until replacement of the cutter body, bit holder, and/or pick is required. The rotatable bit cartridge may include a forward end with a brazed diamond coated, layered, and/or diamond table bit tip insert or a brazed tungsten carbide bit tip insert. The rotatable bit includes a body that includes a generally cylindrical and/or a tapered first bore extending axially inwardly from a forward end of the body and a bit tip insert comprising a tip and a base subjacent the tip, a portion of the base adjacent a distal end of the bit tip insert disposed within the first bore of the body.

This disclosure relates to a system for removing road material. In an embodiment, the system may include a milling drum and at least one pick mounted on the milling drum. Furthermore, the pick may include polycrystalline diamond at least partially forming one or more working surfaces of the pick.

The present disclosure provides a cutting head adapted to removably couple to a bit body of a drill bit assembly. The cutting head includes a leading cutting tip for cutting into earth and a trailing receiving portion for receiving a second end of the bit body in an internal cavity defined by the trailing receiving portion to allow the cutting head to be removably coupled to the second end of the bit body.

Embodiments described herein relate to material-removal systems and cutting tools that may be used in the material-removal systems. More specifically, for example, the material-removal systems, and particularly the cutting tools thereof, may engage and fail target material. In some instances, the material-removal systems may be used in mining operations.
