Abstract

PURPOSE:To enable excellent cutting to be processed stably at all time by letting each radius of curvature for the inner and outer surfaces of a plurality of edges in a saw blade form be smaller than the inner radius of a main body, and be larger than the outer radius thereof respectively wherein these cutter surfaces are provided for the upper end flange of the cutter main body, and forming a transverse groove in the inner surface thereof. CONSTITUTION:The upper surface of each edge 12 is formed in a saw blade shape, the radius of curvature ra for one section (a) of an outer surface is set to be larger than the outer radius ro of a cutter main body 11, and one section (a) of the outer surface is projected out somehow from the outer circumference of the cutter main body 11. On the other hand, the radius of curvature rb for the inner surface (b) of each edge 12 is set to be smaller than the inner radius ri of the main body 11, and the inner surface (b) is projected out somehow inward from the inner circumference of the main body 11. Then, grooves 12a and 12a transversing to the vertical direction are provided for the inner surface (b) of the edge 12. In the second place, in a cutter 10, chips from a lining member 2 are blown off outwardly because of centrifugal force when a section blocking the branch pipe 7 of the lining member 2 is cut off, a large amount of chips melted by cutting heat is discharged by way of the grooves 12a and 12a in the inner surface 6 of the edge 12, thereby letting excellent cutting be stably processed.
