    Abstract: An excavating tool of the present invention includes a casing pipe that forms a cylindrical shape about an axis line and in which a stepped portion whose inner diameter is decreased by one step is formed in an inner peripheral portion of an distal end; an inner bit where a contact portion which can come into contact with the stepped portion is formed in an outer periphery, which is inserted into the casing pipe from a rear end side in the direction of the axis line, and whose distal end portion protrudes from a distal end of the casing pipe; an engagement convex portion that is disposed on the outer periphery of the distal end portion of the inner bit so as to be retractable; a ring bit that forms an annular shape and is arranged around the distal end portion of the inner bit protruding from the distal end of the casing pipe; and an engagement concave portion that is formed in an inner peripheral portion of the ring bit. The ring bit is rotatable around the axis line integrally with the inner bit in a rotating direction during excavation, and the ring bit is locked so as not to be pulled out to the distal end side in the direction of the axis line in such a manner that the engagement convex portion protrudes to an outer peripheral side and engages with the engagement concave portion. The ring bit can be pulled out to the distal end side in such a manner that the engagement convex portion is retracted to an inner peripheral side.

    Abstract: Provided is a ball end mill that does not interfere with the defect resistance of a cutting edge of which a rotational track forms a convex hemispherical shape. In the ball end mill, a gash 4 is formed at a front end portion of a main end mill body 1 rotated about an axis O and a cutting edge 5 of which a rotational track around the axis 0 forms a convex hemispherical shape having a center C on the axis O is formed at a peripheral edge portion of a wall surface 4A of the gash 4 facing an end mill rotation direction T. A difference between an included angle, which is formed between a straight line connecting a position which is present on the cutting edge 5 and at which a depth of the gash 4 is maximal in a cross-section orthogonal to the cutting edge 5 with the center C and the axis O, and an included angle, which is formed between a straight line connecting a position which is present on the cutting edge 5 and at which a rake angle of the cutting edge 5 is maximal on a positive angle side in the cross-section orthogonal to the cutting edge 5 with the center C and the axis O, is within ±7°.

    Abstract: In an excavation tool of the present invention, an embedding hole 8 is drilled in a distal end portion of a tool body 1 which is rotated about an axis line O and is moved forward to a distal end side in a direction of the axis line O. In the embedding hole 8, an excavation tip 5A in which an embedding portion 6 having an outer cylindrical shape is formed integrally with a cutting edge portion 7 inserts the embedding portion 6 into the embedding hole 8 and causes the cutting edge portion 7 to protrude from the embedding hole 8. In this manner, the excavation tip 5A is rotatable around a central axis C of the embedding portion 6 during excavation, and is attached thereto by being locked so as not to slip toward a distal end side of the embedding portion 6 in a direction of the central axis C.
