Saw blade for cutting marble

A saw blade for cutting marble relates to a saw blade for cutting segment type marble frame of hard and fragile material. The utility model consists of a saw blade body (1), tool bits (2) and end plates (3), wherein the tool bits (2) are fixed at equal interval on one long edge of the strip plate-shaped saw blade body (1), and the end plates (3) are fixedly connected with the two ends of the saw blade body (1). A longitudinal groove (4) where the saw blade body (1) can be inserted is arranged on the segments (2-2) of the tool bits (2), and the lower edge of the saw blade body (1) is inserted into the groove (4). The tool bits (2) can also be welded together with the body (1). The utility model can be applied to cut bigger plates and the saw blade has small oscillating quantity during cutting, thereby resulting in a narrower kerf. The utility model can also make a plurality of saw blades to be arranged in parallel for synchronous working, thereby improving production efficiency.
