New type description: [New technical field] - The boring needle structure with the "4" discharge groove, especially the two-stage spiral inclination adjustment of the seeding /, all the debris discharge grooves _ discharge The three sections of the ditch are adjusted so that the head section of the drill has a symmetrical cleavage and is a burr structure in which the U-turn groove of the body section overlaps. X [Prior Art] rr===== ^ Improve, efficiency and reduce manufacturing costs. For the pure enamel on the printed circuit board, it is to find a plurality of overlapping printed circuit boards for through-hole processing, so the use of the slave _ 'and the drill collar has sufficient strength and money to turn In the traditional boring needle structure, there are two opposite-turning turbulent n-hole boring habits, the design of the debris plus the f-chip space, the discharge and the tail section of the shoulder, the genus can bear the following = The degree of design of mosquitoes - the spiral limbs of the chip discharge ditch, although this design can be used for the current - general New Zealand - see the reading, but its shortcoming is that the force m is increased and the need to increase, shoulder space and row of force When 'the tail section of the genus and the swarf has reached the upper limit can not be adjusted' easy to encounter The design bottleneck, while the rigidity of the bur is easy to be affected by the angle of the spiral. In another type of burr structure, in order to obtain better machinability, the core of the boring is designed from the drill tip to the type of cone, which is The thicker surface of the core becomes larger, so that the drill needle t and the two scraps are gradually reduced. Therefore, the chip discharge end of the drill needle has a spiral angle of the driver's small angle, and the chip discharge groove at the rear end of the drill needle has a larger spiral angle. By the rear section of the chip discharge groove, the spiral vorticity is large, the distance between the _ distance and the space is increased, and the chip 3 of the rear part of the bur is solved. The design of the spiral angle of the larger chip discharge groove is prone to serious problems, resulting in the processing of the bur. Poor quality and broken needle problem. Because the spiral angle of the chip discharge groove of the drill pin will affect the drilling force, the larger the angle, the larger the space, so the value of the station L and the row are secret. The spiral angle of the discharge groove (4) is large - the small I structure is wrong to increase the size of the front end of the drill needle. The design of the end of the thread is smaller and the thickness of the drill core is gradually larger than the axis = the image is contradictory, making the drill easy to produce. == Bad and broken needle problem - π X;耵The above-mentioned design of the machine mouth quality, whether it is a single i-rotation angle, or a spiral angle front end, a small rear end, a large X-end and a large-cut design, all have the problem of the needle amount, and both of them have adverse effects on the processing. Use and not to ask for [new content] Dreams are the problem, the purpose of this creation is to provide a kind of burr structure, the basin == ι;! ί=The section is called Shuangergou, rigid strength, with an increase容屑空;;:; force one cut = out of the ditch, in order to improve the burr to complete the above purpose, the creation of the luxury department; and - drilling blade Qiu, check the poor burrow structure contains: - drill The handle and the body drilling knives sequentially include a drill tip and a head section, and the outer grip of the body section is smaller than the head section, and - the first-cutting cleavage of all the debris discharge grooves is spiraled by the drill tip and discharged The groove includes a first head segment spiral inclination angle and the second drill edge and the first-cut shoulder have a first/observation and a second body miscellaneous inclination, wherein the first corner of the angle is cut; (10) the first-cutting groove and the Having a second chat segment spiral tilting: the letter is separated, and the second body segment has a second tilt angle I, having a body portion All angles of the first coil genus drained overlap.

The outer diameter of a head section 18 and a body handle portion and a further section 20 is smaller than the outer diameter of the head section 18.
