A tool, for removing a cutting bit from a rotor of a rotor assembly of a machine, includes one or more input interfaces and one or more lighting units. The one or more input interfaces are configured to be actuated to perform one or more functions associated with removing the cutting bit from the rotor. The one or more lighting units are configured to be activated upon the actuation of the one or more input interfaces to illuminate at least a portion of the rotor assembly when performing the one or more functions associated with removing the cutting bit from the rotor.

A bit holder that includes a front body portion and a shank axially depending from the bottom of the front body portion. The shank of the bit holder includes at least one slot and at least one annular ring disposed partially or nearly circumferentially around the shank. The slotted shank of the bit holder and the at least one annular ring are radially compressible to achieve and maintain an interference fit when inserted into a bore of a base block.

A bit removal device may include a support, an extractor coupled to the support, and an actuator. The support is configured to engage a bit holder from a front side of the bit holder. The extractor is configured to engage a bit from the front side of the bit holder. The actuator is configured to move the extractor relative to the support to extract the bit from the bit holder.

A device for extracting a cutting bit from within a securement hole in cutting equipment. The device has a base body having an open base end that contact the cutting equipment that surrounds the cutting bit. An elongated drive body having a threaded member with a threaded bore, rotatively contacts the base body, and a threaded post having a threaded portion is threaded within the threaded bore of the elongated drive body, and has a lower end extending into the base body. A pair of bit jaws are attached to the lower end of the threaded post, each having an in-turned ledge for engaging a peripheral groove of the cutting bit. By rotating the drive body, the threaded post is drawn axially upwardly, and with it the pair of bit jaws, to withdraw the cutting bit from the hole in the cutting equipment.

Mineral bits (10, 100) and associated mounts (30, 116, 200) for use during excavation and mining operations are disclosed. An exemplary bit (10) has a front region (12) and an opposite rear region (14) and comprises a head portion (16) and a mounting portion (18) secured to the head portion (16). The mounting portion (18) can be configured to be releasably retained by a mount (30). A rounded transition (22) disposed in the front region (12) of the bit between the head portion (16) and the mounting portion (18) provides a clearance (C) between the head portion (16) and the mount (16). Mineral bits (10, 100) disclosed can be inserted into and withdrawn from mounts (30, 116, 200) by linear and/or rotational movement.

An improved bit retainer having a retainer body that includes an arcuate top portion defining a radially expandable area. The bit retainer including a pair of opposed arcuate legs depending from the arcuate top portion, the pair of opposed arcuate legs having a radial cross-section greater than the radial cross-section of the radially expandable area. Each leg includes a cavity adjacent a distal end of the leg. The bit retainer adapted to engage an annular groove of a shank of a pick or unitary bit/holder when the bit is inserted into a bore of a base block and retain the bit within the bore of the base block. A first embodiment of the bit retainer having a flat side profile and a second embodiment of the bit retainer having a curved side profile.

A pick for mineral winning includes an elongate shank configured to be positioned into a cavity of a holder. A profile is defined on an outside surface of the shaft which includes a first surface formed into the profile and disposed to receive a leveraging device to enable a first forced translational movement of the shaft relative to the holder, and a second surface formed into the profile and disposed to receive the leveraging device to enable a second forced translational movement of the shaft relative to the holder.

A unitary diamond bit/holder, tool, and/or pick assembly that includes a forward extension axially extending from a body of the bit/holder and a tungsten carbide ring mounted in an annular trough at a forward end of the body around the forward extension. An axially shortened diamond tipped bit tip insert is brazed to the forward extension, within a bore of the forward extension, and/or to a tungsten carbide plug which is then seated within a bore of the forward extension.

A tool includes an actuator assembly, a rod, a first nut, and a second nut. The actuator assembly includes a cylinder, a ram, and a bore extending through the cylinder and the ram. The cylinder includes an internal chamber supporting the ram, a first end, a second end, and a reaction surface positioned proximate the first end. The ram is movable relative to the cylinder and positioned adjacent the second end of the cylinder. The rod extends through the bore of the actuator assembly. The first nut is selectively coupled to one of a first end of the rod and a second end of the rod, and defines a first dimension larger than the bore width of the bit block. The second nut is selectively coupled to the other of the first end of the rod and the second end of the rod, and defines a second dimension less than the bore width.
