Abstract
An indexable mill includes a tool holder and an indexable bit. The tool holder has a positioning shaft whose one side is provided with a braking block that has curved mortises. The positioning shaft is centrally provided with a threaded hole. The indexable bit is centrally provided with a positioning hole. The positioning hole of the indexable bit has its one side formed with a braking notch. The plug-socket like connection between the positioning shaft of the tool holder and the positioning hole of the indexable bit provides a first positioning function. The wrapping, curved surface contact between the braking block and the braking notch provides a second positioning function. The dual positioning enhances stability and rigidity of the combination.
