ABSTRACT:
A string saw includes a housing, and an air box. The housing includes a first casing and a second casing combined with each other. The air box is mounted in the housing and has an inside formed with a receiving chamber communicating with the storage space of the first casing, so that the cut chips during the sawing process can be introduced from the storage space of the first casing into the receiving chamber of the air box. Thus, the string saw can provide the dust collection and chip drainage function.
