The invention belongs to the technical field of drill points, and discloses a PCB drill point. The PCB drill pin comprises a pin handle and a pin body arranged at one end of the pin handle, a conical tip part is arranged at the end, away from the pin handle, of the pin body, the conical tip part comprises first rear tool faces and second rear tool faces, the two first rear tool faces are arranged in a central symmetry mode along the rotating center of the pin body, and the two second rear tool faces are arranged in a central symmetry mode along the rotating center of the pin body. The first rear tool face and the second rear tool face intersect to form a center line and a chisel edge, two spirally symmetrical main chip grooves are formed in the needle body in the length direction of the needle body, a main cutting edge is formed in the intersection position of the main chip grooves and the first rear tool face, and the main cutting edge and the chisel edge are located on the same straight line, so that the stress during drilling is reduced, and the drilling efficiency is improved. According to the PCB drill point, the stability of the PCB drill point in the drilling process is enhanced, so that the drilling precision is improved, heat generated by the PCB drill point in the drilling process can be reduced, abrasion of the main cutting edge is reduced, and the quality of a hole wall is effectively improved.
Description
technical field [0001] The invention relates to the technical field of drill needles, in particular to a PCB drill needle. Background technique [0002] PCB drill needle, that is, the drill needle for processing printed circuit boards, printed circuit boards are important electronic components, the support body of electronic components, and the carrier for electrical connection of electronic components. [0003] The double-edged PCB drill needle in the prior art usually includes a needle handle and a needle body, the needle body is arranged at one end of the needle handle, and the end of the needle body away from the needle handle is provided with a cutting portion, such as figure 1 As shown, the cutting part is composed of two first flanks 100 and two second flanks 200, and the two first flanks 100 and the two second flanks 200 intersect at the rotation center 500 of the needle body The two straight lines that intersect the first flank 100 and the second flank 200 and pass...
