Claims

[Scope of utility model registration request]

A relatively large-diameter mounting hole is drilled in the axial direction of one end of the tile body, and a relatively small-diameter screw hole is further drilled at the bottom of the hole, while the holder body has a conical peripheral surface. and a holder for adjusting the outer diameter of the grindstone, which is made up of a mounting screw part continuous to the end on the small diameter side of the circumferential surface, the holder main body is placed in the mounting hole, and the mounting thread part is screwed into the screw hole. , and a spring is compressed between the end face of the mounting screw part and the bottom of the screw hole, and it is assembled to the tile body so that it can move forward and backward in the axial direction, and the assembly position is fixed with bolts, and the adjustment holder is A plurality of grindstone mounting holes are formed at equal intervals in the circumferential direction on the circumferential surface of the tile body corresponding to the conical circumferential surface. The grindstone, which is inserted into the grindstone mounting hole and fixed with a bolt, has a tapered surface that slopes toward the screw hole side as it goes in the direction. An internal grinding tool comprising: a tapered surface that contacts a peripheral surface; and a tapered surface that contacts a tapered surface of a grindstone mounting hole.
