A tool for removing material includes a body, an ultrahard insert, and a matrix. The body has a forward portion, an opposing rear portion, and a longitudinal axis therebetween. The ultrahard insert includes an ultrahard material, and the ultrahard insert is mounted to and contacts the body proximate the forward portion. The matrix contacts the body and the ultrahard insert. The matrix is mechanically interlocked with the body and at least a portion of the matrix is positioned circumferentially around at least a portion of the forward portion of the body.

A cutter bit adapted to be fixed onto a working surface of a rotating drum of a milling, planing, mining or reclaiming machine is provided. The body of the cutter bit is generally formed of a hardened steel, the cutting surface may be a diamond composition fixed in a step in the upper end of the cutter bit. The cutter bit includes a cutting surface, and the cutting surface may include non-parallel side edges and an upper cutting edge parallel to a lower edge. The lower edge may be any length sufficient to inhibit unintended angular displacement of the cutting surface during operation of the working surface. Alternatively or in addition, the cutting surface may be defined by three edges to allow the cutting surface to be removed and repositioned in at least a second orientation.

A shaped article can include a substrate formed from a glass material, a glass ceramic material, or a combination thereof and a cavity formed in the substrate. A sidewall of the cavity can have a random textured surface with a surface roughness of less than or equal to 300 nm. A method of machining a protrusion in a graphite block can include translating a cutting tool in a first longitudinal direction toward the graphite block to engage the graphite block with the cutting tool while rotating the cutting tool about a rotational axis without translating the cutting tool in a lateral direction, then translating the cutting tool in a second longitudinal direction away from the graphite block without translating the cutting tool in the lateral direction to disengage the cutting tool from the graphite block. A shaped article can be formed by pressing a preform with a monolithic graphite mold.

A floor leveling apparatus and method for cutting parallel grooves in a hardened body which is configured to assist in utilizing a grinder to finish surfaces in a planar manner.

A self-propelled construction machine comprises a machine frame, at least three travelling devices, at least one hydraulic drive system for driving at least two travelling devices, wherein the hydraulic drive system comprises at least one controllable hydraulic motor with variable displacement volume and at least one hydraulic pump, at least one working device (e.g. a milling drum), for working the ground pavement. A detection device detects fluctuations in the longitudinal speed of the construction machine during movement thereof, wherein a control unit alters the displacement volume of the at least one controllable hydraulic motor as a function of the detected fluctuations so that the natural frequency of the hydraulic drive system is altered, wherein the control unit adjusts the discharge volume of the pump as a function of the amount of adjustment of the displacement volume in such a fashion that the specified drive speed remains constant.
