PROCESSING TOOL AND PROCESSING TOOL ASSEMBLY

A processing tool includes a long cutting portion with a connecting surface and at least one clamped portion which is fixed to the connecting surface. The long cutting portion extends along a longitudinal direction. Each of two sides of the long cutting portion along the longitudinal direction is an abutted end. A bottom portion of each of the abutted ends is connected to the connecting surface, and a top portion of each of the abutted end is away from the connecting surface. A first length is defined between the top portions of the abutted ends, and a second length is defined between the bottom portions of the abutted ends, wherein the first length is smaller than the second length. A processing tool assembly is provided as well. With such design, the processing tool thereof could be changed easily. Multiple workpieces could be simultaneously cut, and the accuracy thereof could be enhanced.
