| 20100119314 | CUTTING INSERT AND CUTTING METHOD - A cutting insert, wherein: a cutting edge part having a quadrangular shaped cutting face, which is provided with a pair of side cutting edges extending in a longitudinal direction of an insert body, and a front cutting edge between ends of the side cutting edges that extends in a direction that intersects the longitudinal direction, is formed at an end of the insert body having a bar-shape; and viewed from a direction facing the cutting face perpendicularly to the longitudinal direction, at least one of a pair of corner edges where the side cutting edge and the front cutting edge intersect is formed in a convex shape such that it has a point of inflection at which, after a tangent line that makes contact with the corner edge rotates in a direction extending in the longitudinal direction along the corner edge from the front cutting edge, its direction of rotation changes, and it joins the side cutting edge. | 05-13-2010 |
| 20100178116 | Cutting tool for machining inner surface of hole, and method for cutting the same - The cutting tool for machining an inner surface of a hole is provided with a cutting tool main body extending in the shape of a shaft, a cutting edge portion mounted on a head portion of the cutting tool main body so as to radially-outwardly protrude with respect to the center axis of the cutting tool main body, and a coolant hole formed at the cutting tool main body so as to have an opening at a position apart from the cutting edge portion on a circumferential surface of the head portion of the cutting tool main body, thereby flushing out a coolant from the opening to an axially orthogonal plane orthogonal to the center axis and also along a protruding direction at which the cutting edge portion protrudes. The opening of the coolant hole faces a direction different from the protruding direction of the cutting edge portion in the radial direction with respect to the center axis. | 07-15-2010 |
| 20100178117 | Detachable insert-type cutting tool - The detachable insert-type cutting tool is provided with a holder, a head member which has an insert seat on which a cutting insert is detachably mounted and which is detachably attached to a head portion of the holder so that an attachment surface of the head member is closely in contact with an attachment surface of the holder, a coolant hole which is formed inside the holder so as to be opened on the attachment surface of the holder, and a first groove which is formed on the attachment surface of the head member, communicating with the coolant hole opened on the attachment surface of the holder and extending so as to be opened toward a cutting edge of the cutting insert mounted on the insert seat. | 07-15-2010 |
