Abstract

The invention discloses a reamer and screw tap compound tool. The tool comprises a reaming drill bit, a tap screw and a shank connected in sequence, wherein the reaming drill bit comprises a reaming drill bit body, a drill tip, a cutting edge and a chip removing groove; the drill tip is positioned at the top end of the reaming drill bit body; the cutting edge and the chip removing groove extend to the tail end of the reaming drill bit body from the drill tip; the tap screw comprises a tap screw body, a cutting cone and a chip holding tank; the top end and the tail end of the tap screw body are respectively connected with the reaming drill bit body and the shank; the cutting cone extends from the top end of the tap screw body to the tail end, and is provided with thread teeth; and the chip holding tank extends from the top end of the tap screw body to the shank. When the reamer and screw tap compound tool is used, the reaming and the tapping can be finished by only needing one procedure, so that the efficient production of products, the reduction of machining cost and the improvement of product precision are facilitated.

Description

technical field [0001] The invention relates to a machining tool, in particular to a composite tool of a reaming drill and a tap. Background technique [0002] Drilling and tapping in the prior art often require two processes to carry out. First, the workpiece is clamped, drilled with a drill bit, and then the cutter is switched to a tap, and then tapped. It causes many processing steps and complicated operation, which is not conducive to the efficient production and precision improvement of products. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a reaming drill and tap compound cutter which increases processing efficiency, reduces processing cost, and improves product precision. [0004] The technical scheme adopted in the present invention is: [0005] It includes a reaming drill bit, a tap and a tool holder connected in sequence; the reaming drill bit includes a reaming drill bit body, a dri...
