Document Type and Number:
WIPO Patent Application WO/2023/047756
Kind Code:
A1
Abstract:
Provided is a disk-shaped rotating tool in which cutting vibration and cutting noise are less likely to occur than conventional technology. This disk-shaped rotating tool has: a base metal 10 in which one or more slits 15 penetrating the front and rear surfaces are formed; and a large number of teeth 20 provided on the outer circumference of the base metal 10 so as to protrude radially outward, wherein the slit 15 is folded back one or more times and defines a finger piece having a thick tip shape, and the length of the finger piece is at least three times the average value of the width of the root and the width of the widest portion. By defining the finger piece by the slit 15 and making the shape of the finger piece a thick tip shape, it is possible to effectively suppress the occurrence of cutting vibration and cutting noise. It is preferable that at least one among the slits 15 be repeatedly folded back four or more times to define four or more finger pieces. In this case, the finger pieces are defined such that the orientations thereof are alternately switched. It is also preferable that the angle formed by both lateral lines of the finger piece is 1° or greater.
