Abstract
A tool holder has a holder body, a chuck, and a clamping nut. The chuck has an annular groove, a nut positioning portion, and a cutting surface. The cutting surface is formed on a periphery of the nut positioning portion by cutting. The clamping nut has a protruding edge. When assembling the chuck and the clamping nut, the cutting surface allows the protruding edge to easily avoid and pass by the nut positioning portion, enter the annular groove, and be engaged in the annular groove, which lowers difficulty of assembly. During disassembly, the protruding edge is configured to abut the nut positioning portion, which allows the chuck to be easily detached from the holder body together with the clamping nut when unscrewing the clamping nut from the holder body.
