According to the utility model discloses an embodiment, wherein above-mentioned diamond tooth piece outer lane width is greater than the inner circle width, and inside and outside both ends have the fillet.

A production process for machining an embossed saw blade comprises the following steps:

step a: providing a circular substrate;

step b: cold-press molding the diamond tooth block on the round substrate;

step c: hot-pressing, sintering and forming, and cooling;

step d: stamping the embossing part by adopting a stamping die with embossing;

step e: and (6) surface treatment.

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

through the outer lane at circular substrate ring portion hot pressing diamond tooth piece of colding pressing, the inboard of central authorities' ring portion sets up the knurling portion, improves cutting strength, avoids the relatively poor trouble of durability.

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