Drill bit for processing thin flexible material

Abstract

The invention relates to a drill bit for processing a thin flexible material. The drill bit is a three-point drill and comprises a shank portion and a working portion which are arranged in sequence, the tail end of the working portion is a cutting portion which has three smoothly-connected cutting edges located in the same straight line, and the ends of the three cutting edges are located at the same height. Compared with the prior art, the drill bit is designed according to the characteristics of the thin flexible material, and the drill bit being the three-point drill comprises the three cutting edges located on one horizontal line. When the thin flexible material is processed, the three cutting edges are in contact with the material at the same time, the two cutting edges on the outer side are used for processing the material, the cutting edge in the middle is used for fixing the thin flexible material, the structure is simple, the cost is low, manufacturing is convenient, the thinflexible material can be effectively cut and processed, the excellent processing effect can be achieved, and the processing precision is improved.

Description

technical field [0001] The invention relates to the technical field of processing thin flexible materials, in particular to a drill bit for processing thin flexible materials. Background technique [0002] The knives used in general material processing are aimed at hard materials, but for thin flexible materials (such as soft metal sheets, cloth, plastic sheets or paper, etc.), it is easy to deform during the processing of the tool, which is very unfavorable for accurate processing. . [0003] In view of the particularity of thin flexible materials, many current cutting tools cannot punch holes in thin flexible materials, not only failing to achieve the required precision, but also often failing to achieve the desired effect. Contents of the invention [0004] The object of the present invention is to provide a drill bit for processing thin flexible materials in order to overcome the above-mentioned defects in the prior art. [0005] The purpose of the present invention ...
