    摘要： A processing apparatus includes: an apparatus main body including a base portion that is movable and a liquid supply unit that supplies a liquid to the base portion; a chuck portion connected to the base portion and including an attachment hole that is open outward; and a processing tool detachably mounted on the chuck portion. The processing tool includes a cylinder fitted into and held by the attachment hole, a drive unit disposed inside the cylinder and including a rotating body to be rotated around a central axis by the liquid introduced from the liquid supply unit via the base portion, a rotary shaft protruding outward from an inside of the cylinder along the central axis to rotate integrally with the rotating body, and a tool portion connected to a tip of the rotary shaft.

    摘要： A cutting tool (100) includes a shank (20) having an insertion portion (22) protruding from a shank main body (21), a head (40) in which an insertion hole (43) into which the insertion portion (22) is inserted is formed, and a spacer (50) disposed in a gap between the shank main body (21) and the head (40). The insertion portion (22) has a tapered outer circumferential surface (32A) which gradually decreases in diameter from the other side toward one side in the axial direction. The insertion hole (43) has a tapered inner circumferential surface (44A) coming into surface contact with the tapered outer circumferential surface (32A). A head end surface (46) of the head (40) which faces the other side in the axial direction comes into surface contact with a surface facing one side in the axial direction of the spacer (50).
