A slotting tool body includes a disc-like cutter portion and a shank portion projecting rearwardly therefrom. The cutter portion includes a resilient clamping portion having a peripherally disposed insert receiving slot. The shank portion includes a peripherally disposed forward shank recess that is axially adjacent the cutter portion. A radially inward portion of the insert receiving slot merges in the rearward direction with the forward shank recess. A cutting insert is releasably and resiliently clamped in the insert receiving slot to form a rotary slot cutting tool. The cutting insert includes two cutting portions that each include a long and short insert lateral extension, the long insert lateral extension being longer than the short insert lateral extension. The longest insert lateral extensions are orated on opposite sides of the cutting insert.

A cutting insert includes: an upper face including a virtual reference surface and an upper inclined surface extending to be inclined upward from the virtual reference surface; a lower face disposed below the upper face and including a lower inclined surface extending to be inclined with respect to the virtual reference surface; and a plurality of side faces connecting the upper face and the lower face. An insert bore is formed to penetrate through the upper face and the lower face along a central axis perpendicular to the virtual reference surface. A major cutting edge is formed at an edge at which the upper inclined surface meets any one side face among the plurality of side faces. A first angle between the side face, on which the major cutting edge is formed, and the upper inclined surface is greater than a second angle between the central axis and the lower inclined surface.

An insert configured to be assembled to a tool for cutting a workpiece, includes: an upper surface including first to fourth upper corner portions formed in respective quadrants divided by a first imaginary vertical axis and a first imaginary horizontal axis that are perpendicular to each other; and a lower surface formed below the upper surface in a height direction and including first to fourth lower corner portions formed in respective quadrants divided by a second imaginary vertical axis and a second imaginary horizontal axis that are perpendicular to each other. A lower ridge portion protruding downward in the height direction is formed on the lower surface, and extends across the second and fourth lower corner portions, which are symmetrical with respect to a center of the lower surface

A land preparation tool includes a tool body having a longitudinal axis, a cutting surface having a distal end and a blade positioned at the distal end, and a mounting interface disposed on the tool body opposite the cutting surface. The mounting interface has an apex extending along the mounting interface parallel to the longitudinal axis, a mounting surface extending from the apex, another mounting surface extending from the apex, and an opening. A channel extends from the opening of the mounting interface into the tool body.

A cutting body rotatable about a tool axis has an insert receiving pocket with a seat surface at an axial forward end thereof. The seat surface has a plurality of abutment elements, including an axial abutment element having an axially forward facing abutment surface and at least one radial abutment element. In a top view of the insert receiving pocket, the axially forward facing abutment surface forms an external acute clamping angle with a radially outward facing pocket wall. A rotary cutting tool includes the cutting body, and a cutting insert removably secured in the insert receiving pocket, having a base surface in contact with the seat surface. The at least one radial abutment element occupies or is occupied by at least one radial abutting element of the base surface, and the axially forward facing abutment surface is in contact with an axial abutting surface of the base surface.

A cutting insert includes a rake end surface having four corners and, in a center thereof, a central surface portion. A supporting end surface has four corners and, in a center thereof, a central supporting surface portion. A peripheral side surface extends between the rake end surface and the supporting end surface. The peripheral side surface includes two opposing major side surfaces. A hole extends through the cutting insert from one of the major side surfaces to the other of the major side surfaces, wherein the central surface portion is disposed at a greater distance from a central axis (A) of the hole than is the central supporting surface portion. The single-sided cutting insert has a corner radii or cutting edge radii that extend over at least a quarter of a width of the cutting insert.

A land preparation tool includes a tool body having a cutting surface, mounting surfaces disposed on the tool body opposite the cutting surface, and opposing side surfaces each extending between the cutting surface and a different one of the mounting surfaces. One mounting surface angles inwardly from a distal edge of a side surface toward the tool body. Another mounting surface angles inwardly from a distal edge of the other side surface toward the tool body. An opening is disposed on the tool body opposite the cutting surface and between the mounting surfaces. Other embodiments are described and claimed.

A land preparation machine includes a land preparation apparatus connected to a lift assembly of a vehicle. The land preparation apparatus has a rotatable drum and a plurality of tools assemblies disposed thereon. A tool assembly of the plurality of tool assemblies includes a tool holder and a tool attached thereto. The tool includes a tool body having a cutting surface disposed on a side of the tool body, an apex disposed on a different side of the tool body opposite the cutting surface, and tool mounting surfaces disposed on the side of the tool body opposite the cutting surface. One tool mounting surface extends outwardly from the apex at an angle toward the cutting surface. Another tool mounting surface extends outwardly from the apex, opposite the other tool mounting surface, at an angle toward the cutting surface. Other embodiments are described and claimed.

A milling insert includes a first axial face, a second axial face, a first radial face, a second radial face parallel with the first radial face, a cutting face, and a generally V-shaped seating face formed with a first seating surface and a second seating surface. The first axial face defines a secondary clearance surface that is at least partially axially recessed from the first axial face and oblique to the first radial face. The first seating surface and the second seating surface are formed at an angle substantially equal to a radial rake angle when the cutting insert is mounted in the insert seat of the milling cutter. As a result, the seating face produces at least one seating surface that is substantially perpendicular to the tangential cutting force, F.sub.T, thereby reducing movement of the insert when tangentially mounted in the insert seat of the milling cutter.

A land preparation tool includes a tool body having a cutting surface, a mounting surface, an opening, and a channel. The cutting surface has a blade positioned at a distal end thereof. The mounting surface has a non-planar profile and is disposed on the tool body opposite the cutting surface. The opening is disposed on the mounting surface and the channel extends from the opening at least partially into the tool body. Other embodiments are described and claimed.
