Description

Technical Field

[0001] The utility model relates to the technical field of cutting tools, and more particularly to an improved cutting tool. Background Art

[0002] A turning tool is a tool with a cutting portion used for turning operations. It is one of the most widely used tools in cutting operations. The working portion of a turning tool is the part that generates and processes chips and includes structural elements such as the cutting edge, a structure that breaks or gathers the chips, space for chip removal or storage, and channels for the cutting fluid.

[0003] Based on the above, the inventors found that in order to break or roll up the waste chips cut off from the parts, the existing cutting tools usually have a cutting groove on the top of the blade, but the cutting groove is only open at one end close to the cutting edge, and the edge of the opening is the cutting edge. When the chips are broken or rolled up, the waste chips are not cut in time and are easily accumulated in the groove, resulting in poor chip removal, affecting the cutting operation of the workpiece, resulting in poor use effect and reduced processing efficiency. Therefore, in view of this, the existing structure is studied and improved to provide an improved cutting tool in order to achieve the purpose of greater practical value. Utility Model Content
