摘要： A blade for a cutting tool is provided having plane parallel faces with V-shaped upper and lower jaws, the jaws being separated at one plane parallel face by a web, the upper and lower jaws being shaped to receive and prevent lateral movement of an insert when retained by the jaws. The insert is shaped to cooperate with the blade. The insert has a cutting edge mounted on a cutting portion separated from the seat portion by a rebate.

摘要： A three-sided indexable, detachable insert having a positive rake for a cutting tool. The insert has three edge faces and two side faces, each edge face having one or more recesses which extend across the whole of the edge face, substantially transversely to the cutting edge formed where each edge face meets one of the side faces of the insert. The recesses are spaced apart from a plurality of coplanar lands, the number of recesses on each edge face being the same. The width of the recesses is the same as half the width or less than half the width of the intervening lands. Each intervening land is positioned such that is provides in operation a cutting edge to wipe the material left by the recesses of any of the other sides. Each edge face and cutting edge of the triangular insert having a positive rake is designed to have recesses and lands in positions such that when two or more of the inserts are placed side by side, the lands of one or more inserts are in complementary registry with the recesses in at least one other insert. This presents a continuous but staggered line of cutting edge lands when the inserts are positioned in a milling cutter.
摘要翻译：具有用于切削工具的正耙的三面可转位的可拆卸插入件。插入件具有三个边缘面和两个侧面，每个边缘面具有一个或多个延伸跨越整个边缘表面的凹部，基本上横向于形成在每个边缘面与嵌入件的一个侧面相交的切割边缘。这些凹槽与多个共面平台区域间隔开，每个边缘面上的凹槽的数量相同。凹槽的宽度与宽度的一半相同或小于中间区域宽度的一半。每个中间的区域被定位成使得在操作中提供切割边缘以擦拭由任何其它侧面的凹部留下的材料。具有正耙子的三角形插入件的每个边缘面和切割边缘被设计成具有凹槽和平台的位置，使得当两个或更多个插入件并排放置时，一个或多个插入件的平台与至少另一个插入物中的凹部。当刀片定位在铣刀中时，这呈现了连续而交错的切割刃区线。

摘要： An indexable disposable insert is described having eight contiguous edge faces of equal length and two octagonal side faces having alternate corners with equal obtuse angles, cutting edges being formed at the junction of at least one of the octagonal side faces and each of the eight contiguous edge faces. Four identical pairs of cutting edges of equal length arranged about an obtuse angle are provided. The obtuse angles which may vary in the range 135.degree. to 170.degree. but are preferably 160.degree.. The insert can have chip breakers applied to it.

摘要： The present invention provides a drilling tool having a shank and at least one pair of identical cutting inserts, the inserts having an octagonal shape having alternate equal obtuse angles. Each of the inserts is arranged such that they each have a different radial displacement from the turning axis of the drill, the inner insert having a cutting path which overlaps the turning axis of the drill and the next outer insert having a cutting path which overlaps the cutting path of the inner insert. The cutting path of each insert is formed by the cutting edges either side of the obtuse angles of the insert.
