In order to solve the technical problem, the utility model discloses a diamond ripple saw bit, include: a substrate; the toothed ring is arranged on the edge of the base body; convex round parts are arranged at two sides of the center of the base body, and a plurality of first heat dissipation holes and a plurality of second heat dissipation holes are arranged at the periphery of each convex round part; the mounting hole is positioned in the center of the base body and the convex round part; the gear ring is provided with a plurality of V-shaped convex teeth and a plurality of tooth grooves, the openings of the V-shaped convex teeth are consistent and are mutually connected towards the outer side of the base body to form a rack, and the tooth grooves are arranged in the V-shaped convex teeth; the surfaces of the V-shaped convex teeth are provided with convex cutting edges.

Furthermore, 3 to 20 first heat dissipation holes are arranged at the edge of the convex part at intervals.

Furthermore, the first heat dissipation hole is semicircular.

Furthermore, 3-20 second heat dissipation holes are arranged on the outer side of the convex portion.

Further, the racks on the two sides are not axially symmetrical about the center point of the base body.

Furthermore, the width of the gear ring accounts for one sixth of the radius of the base body.

Further, the width of the convex teeth is 1 mm.

Compared with the prior art, the application can obtain the following technical effects:

the utility model is provided with the gear ring at the edge of the base body, racks formed by connecting a plurality of V-shaped convex teeth are arranged at the two sides of the gear ring, and the positions of the racks at the two sides are staggered by the distance of a tooth socket, thereby forming the corrugated gear ring; the ring gear is the diamond material, and the sharpness of corrugated ring gear obtains further promoting.

Of course, it is not necessary for any one product to achieve all of the above-described technical effects simultaneously.
