The invention discloses a multiple-blade rough machining tool. The multiple-blade rough machining tool comprises a tool handle and a tool bit fixedly connected to the head of the tool handle. The toolbit comprises a hard alloy layer formed by a hard alloy and a polycrystalline diamond layer fixedly connected to the hard alloy layer. The polycrystalline diamond layer is provided with multiple cutting blades, and the tool handle is formed by a hard alloy. According to the multiple-blade rough machining tool, due to the fact that the polycrystalline diamond layer is provided with the multiple cutting blades, when the multiple-blade rough machining tool works, the cutting quantity of each cutting blade is small, wear must be controlled due to the small cutting quantity, and therefore the service life of the tool of this kind is prolonged. Meanwhile, by means of the multiple-blade rough machining tool with the multiple cutting blades, material waste can be reduced, the machining efficiencycan be improved, and the
