Description

Technical Field

[0001] The utility model relates to the technical field of cutting tools, in particular to a rotary metal cutting tool. Background Art

[0002] Cutting tools are tools used for cutting processing in mechanical manufacturing. The vast majority of tools are used by machines. The tools used in mechanical manufacturing are basically used to cut metal materials. There are many types of cutting tools, including turning tools, hole processing tools, milling cutters, broaches, gear tools, etc. Among them, hole processing tools need to drill holes through the rotation of the tool. They are tools that process holes from solid materials. Commonly used ones include twist drills, center drills and deep hole drills.

[0003] According to a description of a rotary metal cutting tool disclosed on the Patent Network (authorization publication number: CN 220761097 U), "The present utility model discloses a rotary metal cutting tool, comprising a tool holder, wherein a reserved cavity is provided within the tool holder, a mounting cylinder is fixed at the bottom end of the tool holder, a reserved groove is provided within the mounting cylinder, limiting grooves are fixed on both sides of the reserved groove, a rubber pad is fixed at the top of the reserved groove, a fixing ring is fixed at the bottom end of the mounting cylinder, a tool body is provided within the fixing ring, and through grooves are provided at both ends of the outer side of the mounting cylinder. By providing the limiting grooves, the tool body can be inserted into the reserved grooves during installation. At this time, the limiting grooves are locked on the outer side of the tool body, and the rubber pads contact the top of the tool body. The limiting grooves can improve the tightness of the tool body within the reserved groove, preventing shaking. The rubber pads act as a buffer for the tool body, thereby ensuring the stability of the tool body during use."

[0004] In view of the above description, the applicant believes that the following problems exist:
