    摘要： Described is an end mill with four straight front cutting edges arranged on a front side and a corresponding number of circumferential cutting edges that each emanate from the outer nose of the front cutting edges and are separated from each other by flutes. One of the front cutting edges passes over into a second cutting edge via a free surface intersecting line. The additional front cutting edges lying between the latter in the cutting direction are offset relative to each other by a first angular pitch of 180°, and end before the middle. So that the end mill can be used in an especially advantageous manner for incorporating dimensionally and positionally precise pilot holes or chamfering curved work piece surfaces, the first front cutting edge is offset relative to the second front cutting edge in the cutting direction by a second angular pitch ranging between 173° and 177°, preferably between 174° and 176°, wherein the first front cutting edge is offset relative to the next additional front cutting edge in the cutting direction by a third angular pitch ranging between 90° and 94°, preferably between 91° and 93°.

    摘要： A tungsten steel cutter which is lower cost to use and can increase fabrication efficiency and improve quality mainly includes a shank and a bit screwing at a front end of the shank. Both are made of tungsten steel and formed in an integrated fashion. The shank has a screw hole at the front end and a coupling trough formed at the front end of the screw hole. The bit has a screw bar extended from the bottom end thereof and a coupling neck at the front section of the screw bar. The coupling trough is formed at a depth same as the height of the coupling neck and the coupling trough and the coupling neck are formed at the same size. The bit and the shank have respectively a water discharge passage and a water drawing passage, and a water intake passage that communicate with each other. The water intake passage is formed at a greater diameter than the water discharge passage and water drawing passage. Thus when the bit and the shank are screwed together, in addition to screw coupling of the screw hole and the screw bar, the coupling trough and the coupling neck also form a tight coupling to minimize gaps that might otherwise happen between them like the conventional ones do. The water discharge passage and water intake passage provide cooling effect for cutting fluid and prevent debris from accumulating on the bit and affecting cutting quality. The invention provides a two-section coupling that can save the cost and improve steadiness and fabrication efficiency of precision tools.

    摘要翻译： 使用较低成本并且可以提高制造效率和改善质量的钨钢切割机主要包括在柄的前端处的柄和钻头。 两者均由钨钢制成，并以一体化的方式形成。 柄部在前端有一个螺孔，在螺钉孔的前端形成一个连接槽。 该钻头具有从其底端延伸的螺杆和在螺杆的前部处的联接颈部。 联接槽形成在与联接颈部的高度相同的深度处，并且联接槽和联接颈部以相同的尺寸形成。 钻头和柄部分别具有排水通道和抽水通道以及彼此连通的进水通道。 进水通道形成为比排水通道和抽水通道更大的直径。 因此，当钻头和柄部螺纹连接在一起时，除了螺钉孔和螺杆的螺纹联接之外，联接槽和联接颈部也形成紧耦合，以最小化它们之间可能发生的间隙，就像传统的那样 做。 排水通道和进水通道为切削液提供冷却效果，防止碎屑积聚在钻头上并影响切割质量。 本发明提供了一种可节省成本并提高精密工具的稳定性和制造效率的两段联接。
