摘要： An end mill for finishing the face or side of hard work comprising a shank, a plurality of helix cutting edges on the periphery of the end mill, and a cutting edge section perpendicular to the axis of the end mill having a polygonal shape with three or more angles, the cutting edge being the edge formed at each vertex of the polygonal shape along the axis of the end mill and being circumscribed by an imaginary cylinder, and the end mill being characterized in that the helix direction of the cutting edge is identical to the rotational direction of the end mill. The end mill of the present invention is able to cut the face or side of the hard work at a feed rate several times higher than that of conventional end mills. Moreover, the end mill of the present invention assures superior surface roughness of finished work.

摘要： A router bit is provided with an even number of paired cutting edges. Each pair of cutting edges has opposite helix hands at the same helix angle with respect to the axis of rotation and a portion where the pitch of the cutting edge is constant when the cutting edge is developed along the circumference of rotation in the longitudinal direction. Such router bit is suitable for chamfering and finishing the side of board containing fiber reinforced plastics.

摘要： A tapered slot end mill comprising a shank and a tapered section having a polygonal shape and disposed at the end of the shank, the tapered section being adapted such that the edge formed at each vertex of the polygonal shape along the axis of the end mill is tapered to have a smaller diameter at the end of the end mill and has a helix form, a pair of end cutting edges formed symmetrically at the ends of the edges, with a part of the edge included in the end cutting edge, and a pair of peripheral cutting edges are respectively provided adjacent to the end cutting edges via rake angle surfaces, and the end mill being characterized in that the helix is formed in the direction opposite to the rotating direction of the end mill.
摘要翻译：一种锥形槽端铣刀，其包括柄和具有多边形形状并且设置在柄端部的锥形部分，所述锥形部分适于使得沿着端铣刀的轴线形成在多边形形状的每个顶点处的边缘是在端铣刀的端部具有较小的直径并且具有螺旋形式，一对端部切削刃对称地形成在边缘的端部，边缘的一部分包括在端部切削刃中，并且一对周边切削刃分别通过前角表面与端切削刃相邻地设置，端铣刀的特征在于，螺旋线沿与端铣刀的旋转方向相反的方向形成。
