Therefore, the market demand for micro-classes and other New Zealands will increase accordingly. 'How to improve the quality and quantity of conventional micro-drills, so that they can have Ixk in the market; % of the competition is the manufacturer in this industry. The direction of the research is changed. [New content] Therefore, the creator has the above-mentioned problems and lacks, and is the money-related information. After many evaluations and considerations, he has many years of experience in this business. Through: 4 and modification, the birth of the patent for the improvement of the structure of the micro drill with better strength and stability. The main (4) of the illusion is that the handle has a connecting surface with a preset diameter. The mating surface is connected to the joint of the joint 4, the predetermined diameter of the mating surface is 6 (10) ~ 9 〇% of the diameter of the shank: and the length of the blade to the mating surface is 8. 9 mm ~ 11 . 9 柳可提回彳4 The strength of the drill bit, and the microscopic impact on the rotation The hole has better stability, so the blade can be tested for small resistance and miscellaneous force, so that the micro-bit is not easy to break. The second purpose of this creation is that the connection is the diameter of the handle. ~4 5_% ' _ This „ _ diameter makes the connection part can increase the strength, and when the micro drill bit rotates into the cutting and drilling, the micro drill bit is not easy to break, thus prolonging the service life of the micro drill bit. Another object of the present invention is that the taper and the butt taper touch 12. ~9 M325884 0. The guide angle is such that the handle is engaged with the connecting portion, and the tapered portion is provided with 8. The angle of inclination of ~1 3°, so that the connection part can be connected with the blade part, the strength of the micro drill bit can be improved, and the blade part can be rotated _. When drilling, it is difficult to produce side sway and eccentricity. Can have better stability. [Embodiment] In order to achieve the above object and effect, the technical means and the structure employed in the present invention are described in detail in the preferred embodiment of the present invention as follows, and are fully understood.
