Ultra-thin sawing circular saw web

The utility model discloses an ultra-thin sawing circular saw web, which comprises a circular metal substrate and an alloy tool bit arranged on the metal substrate, wherein the metal substrate is integrally formed by using a circular substrate positioned on the middle part and an annular substrate positioned on the outer side of the circular substrate; the thickness of the circular substrate is greater than that of the annular substrate; and the alloy tool bit is arranged on the outer periphery of the annular substrate. Due to the adoption of the ultra-thin sawing circular saw web, the strength of the metal substrate can be ensured by increasing the thickness of the circular substrate, the cutting effect can be improved by reducing the thickness of the annular substrate, and edge breaking is prevented.
