摘要： A rotatable bit cartridge (10) 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 (118) or a brazed tungsten carbide bit tip insert. The rotatable bit includes a member (120) that includes a generally cylindrical and/or a tapered first bore (138) extending axially inwardly from a forward end of the body and a bit tip insert comprising a tip (128) and a base (126) 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.

摘要： A bit assembly (10) includes a base block (14) and a bit holder (12) having a forward body portion (16) and a shank (18). The forward body portion includes an enlarged tire portion (24) to deflect material and particles removed from the terra firma and protect the base block from damage. The base block includes a base (60) and a shortened front end (62). The enlarged tire portion has dimensions that cover at least all of the shortened from end. The dimensions of the tire portion can also extend beyond the dimensions of the shortened front end.

摘要： Improvements in previous bit assembly components including shortened slotted shanks and shortened base block bore receiving portions disclose relationships between shank differential interference portions and the corresponding base block bores. Changes in the differences in interference angles lead to changes in slot width, length and steel hardnesses in order to provide necessary retaining forces between the shank and base block bore.

摘要： 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.

摘要： An improved diamond coated bit tip insert (60) for a unitary bit/holder, tool, and/or pick for road milling operations that includes a body including a tip (62) and a base (66) subjacent to the tip. The tip of the bit tip insert includes a substrate (63) and an overlay (76) on an outer surface of the substrate. The base of the bit tip insert includes a tapered sidewall (68) or a cylindrical sidewall, the tapered sidewall providing a greater concentration of force applied at an interface of the overlay and the substrate of the tip during a high pressure high temperature (HPHT) process than when using the cylindrical sidewall and the high pressure, high temperature process.

摘要： An improved bit retainer (60, 90) having a retainer body that includes an arcuate top portion (70, 100) defining a radially expandable area (84, 114). The bit retainer including a pair of opposed arcuate legs (62, 64, 92, 94) depending from the arcuate top portion, the pair of opposed arcuate legs having a radial cross-section (78, 108) greater than the radial cross-section of the radially expandable area. Each leg includes a cavity (75, 77, 105, 107) adjacent a distal end of the leg. The bit retainer adapted to engage an annular groove (46) of a shank (20) of a bit holder (14) when the bit holder is inserted into a bore of a base block (16) and retain the bit holder within the bore of the base block.

摘要： A bit holder that includes a front portion and a shank axially depending from the front portion. The front portion having an axial length that is less than the axial length of the shank. A combination bit holder and base block that includes the bit holder with the front portion having an axial length that is less than the axial length of the shank. The base block including a mounting portion and a device receiving portion, the device receiving portion including a length that is the same or less than a length of the mounting portion. The base block having a device receiving portion that includes a length shorter than a length of the mounting portion adapted to provide increased access to the rear of the bit assembly allowing the base blocks to be mounted closer to each other for micro-milling operations. Shortened bit holder shanks are reconfigured from prior art to provide increased holding power between the bit holder shank and base block bore.

摘要： A bit tip insert(316) on a bit/holder, tool, and/or pick for road milling operations that includes a body including a tip and a base subjacent the tip. The bit tip insert also includes at least one heat transfer bore (328) extending from a distal end and/or bottom of the body to a bore termination disposed within the base and/or the tip of the bit tip insert. The at least one bore of the bit tip insert is adapted to allow inward contraction when the overlay transfers heat into the base during operation.
