Abstract

The invention relates to an improved metal cutting tool, in particular to a cutter tool used for panel processing of a mobile phone casing, comprising a cutter body and a cutting head. A step type supporting surface is arranged between the cutter body and the cutting head. The cutting head with a conical surface is positioned on the top of the cutter body. A tool nose is arranged on the top of the conical surface, and a cutting blade connected with the tool nose is arranged on a side of the conical surface. The metal cutting tool has the advantages of reasonable design, simple structure, better intensity, low manufacturing cost, simplified processing procedures, and high work efficiency.

Description

technical field [0001] The invention relates to a cutting tool, in particular to a metal cutting tool used for processing mobile phone shell panels for cutting and drilling. Background technique [0002] The existing cutting tools, especially those used for the cutting and processing of mobile phone casing panels, cannot perform more precise cutting and drilling work according to the needs of the workpiece to be processed and through stable cutting force, and the uneven force can easily lead to blade damage. wear and damage. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a metal cutting tool that highlights the capability of the cutting head and makes the tool strength better in view of the current state of the art. [0004] The technical scheme adopted by the present invention to achieve the above purpose is as follows: a metal cutting tool, including a blade body and a cutting head, a stepped bearing surface between the blade body a...
