| A milling tool is disclosed. The milling tool may include an elongated body having a longitudinal axis and a plurality of cutting inserts. The cutting inserts may each have a cutting edge and a cutting radius and be coupled to the body and spaced along the longitudinal axis. One or more of the plurality of cutting inserts may be adjustable (e.g., mechanically adjustable) between first and second cutting radii. A difference between the first and second cutting radii may be at least 10 μm. The milling tool may include cutting inserts having a plurality of different cutting radii. The milling tool may be configured to have a length that spans an entire height of an engine bore. The cutting inserts having different radii may compensate for dimensional errors in an engine bore diameter that occur when milling a deep pocket. | ||||||

A milling cutting insert includes cutting edges provided as ridges each defined by an upper or lower face and a side face that intersect each other, the cutting edges including a flat cutting edge. The cutting edge include a major cutting edge provided between adjacent ones of corner portions, the flat cutting edge provided at the corner portion, and a minor cutting edge provided between the major cutting edge and the flat cutting edge. A surface roughness of a side face that is continuous with the major cutting edge is higher than a surface roughness of a side face that is continuous with the minor cutting edge. | ||||||

| Milling tools configured to increase surface roughness are disclosed. The tool may include an elongated body having a longitudinal axis and a plurality of cutting inserts coupled to the body and spaced along the longitudinal axis, each cutting insert having a cutting edge. In one embodiment, the cutting edges may have an orientation that is oblique to the longitudinal axis of the elongated body. Each cutting edge may have a first end having a greater cutting radius than a second end. The cutting edges may be offset from the longitudinal axis of the elongated body by an offset angle. In another embodiment, the cutting edges may have a textured or rough surface profile. For example, the cutting edges may have a mean roughness (Rz) of at least 7.5 μm. The milling tools may increase the surface roughness of a milled engine bore to facilitate a subsequent rough honing process. | ||||||

| A substantially square throwaway insert can be used for perpendicular machining if a cutting tool on which the insert is mounted is rotated in either direction. All its four corners can be used as cutting edges. Each cutting edge protrudes outwardly toward the center thereof, as viewed from top of the insert. Also, each cutting edge recedes toward the center as viewed from side of the insert. The insert is mounted on a cutting tool with such an axial rake and a radial rake that each corner of the insert can machine a surface having substantially a right angle. | ||||||

A substantially square throwaway insert (1) which can be used for perpendicular machining if a cutting tool on which the insert is mounted is rotated in either direction. All its four corners (2-5) can be used as cutting edges (6-13). Each cutting edge (6-13) protrudes outwardly toward the center (14-17) thereof, as viewed from top of the insert. Also, each cutting edge (6-13) recedes toward the center (14-17) as viewed from side of the insert. The insert (1) is mounted on a cutting tool with such an axial rake (Ax) and a radial rake (Rd) that each corner of the insert can machine a surface having substantially a right angle. |

| PROBLEM TO BE SOLVED: To use the same throw-away tips even if a cutting tool is for left- handed use, by protruding a cutting edge gradually toward the middle part from corners on both ends, and making it lower gradually toward the middle part from corners on both ends when viewed from the side of the throw-away tip. SOLUTION: Cutting edges continuous to four corners 2, 3, 4, 5 of a square throw-away tip 1 are formed respectively by one straight line, 6, 7 and 8, 9 and 10, 11, and 12, 13 having an angle α to a straight line which connects the corners on both the ends. The two straight lines protrude gradually toward a cutting edge middle part 14 or 15, 16, 17 and look octagonal when viewed in detail. The cutting edges 10, 11 are lower than the corners 4, 5 on both ends toward the middle part 16 at an angle of θ. θ is a value which is determined by α, an axial rake angle and radial rake angle. | ||||||
