摘要： The present invention is a drilling system for cutting flat bottomed holes in work pieces. The tool has two opposing angled cutting edges (62, 64) extending upwardly to create an overlapping web (70) at the center. The angle at which the inner portion of the cutting edge (62, 64) is inclined is increased to create a center point on the cutting surface of the tool. The cutting edge (62, 64) has a rake surface with a positive rake angle (80) that lessens the forces on an insert (35), and also allows for better formation of chips of stock material being removed. Chip breakers (82) can be cut into the cutting edges (62, 64) of the insert (35), further aiding in the removal of stock material.
摘要翻译：本发明是用于切割工件中的平底孔的钻孔系统。工具具有向上延伸的两个相对的倾斜的切割边缘（62,64），以在中心形成重叠的卷筒纸（70）。切削刃（62,64）的内部部分倾斜的角度增加，以在工具的切割表面上产生中心点。切削刃（62,64）具有前刀面，其具有正的前角（80），其减小刀片（35）上的力，并且还允许更好地形成被去除的原料的切屑。可以将切屑（82）切割成刀片（35）的切削刃（62,64），进一步帮助切削料料。

摘要： A drill including a shank (1) having a tip with two cutting inserts (5, 5') located in a main plane (C-C), said cutting inserts (5, 5') having short central cutting edges oriented in a common secondary plane (E-E). Said edges from a pointed centre cutting edge for the purpose of entering a work piece and thereby centering the drill. In the shank two flutes (6, 6') are provided, said flutes (6, 6') extending from the tip to the base end. In each arbitrary cross section along the shank the flutes are located diametrically opposite each other in a duct plane that extends at an angle of 90 DEG to a land plane (F-F) common for two lands on both sides of the ducts, said shank having maximum rigidity in said plane. The secondary plane (E-E) of the centre cutting edge is oriented at an angle of about 90 DEG to the land plane or the main rigidity direction (F-F) at the base end of the shank.

摘要： A method of, and apparatus for, treating an elongate rotary tool (22) that presents a sharp cutting edge (30) are described. The method includes the steps of emitting under pressure from a nozzle (60) an abrasive fluid stream comprising an abrasive grit entrained in a fluid; and impinging the abrasive fluid stream against the sharp cutting edge (30) of the elongate rotary tool (22) for a preselected time so as to transform the sharp cutting edge (30) into a relatively uniformly honed edge. The apparatus (50) includes a rotatable fixture (54) that releasably holds the elongate rotary tool (22). A nozzle (60) that emits under pressure an abrasive steam. The nozzle (60) and the elongate rotary tool (22) are relatively moveable so that the abrasive stream impinges the entire length of the sharp cutting edge (30).

摘要： A cutting tool consists of a holder (12), a blade (14) with cutting teeth (20) and a cap screw (16). The blade (14) has a one-piece axial projection (22) with an encircling positive coupling surface (26) that has a convex polygon contour. A through hole (24) extends through the blade (14). The holder has a front-end recess (28) the circumferential surface of which forms the complement to the coupling surface (26) of the blade (14). The blade (14) with its projection (22) fits into this frontal recess (28) of the holder and is axially secured with the screw (16). The blade (14) provided with a projection (22) is a sintered product and withstands high cutting forces. This makes it possible to use a fracture-proof holder (12).

摘要： A drill tool according to the present invention includes a drill body having an inner insert an outer insert at an end portion of the drill body including four cutting edges rotationally symmetric to each other. The distance from the central axis to the outer insert is farther than that of the inner insert. The cutting edges of the inner and outer inserts are chamfered at the front side and at the rear side in a radial direction of the drill body when mounted in the drill body, respectively. The inner insert and the outer insert are mirror symmetric, and the inner insert and the outer insert are mounted to the drill body such that the ratio of effective cutting edge length of the inner insert to effective cutting edge length of the outer insert satisfies 50:50.

摘要： Some embodiments pertain to a tool that includes a first arm and a second arm that is rotatably connected to the first arm. The first arm includes an opening and the second arm includes a projection that engages threads on a fastener which is installed within the opening in the first arm. During operation of the tool, a fastener is inserted into the opening in the first arm. Pressure is applied to bring the first and second arms together such that the projection engages the threads of the fastener and then deforms the threads. The first arm may include a plurality of threaded openings such that each opening is adapted to receive a different diameter fastener. In addition, the second arm may include a plurality of projections such that each projection is a different size and is aligned relative to one of the openings in the first arm.
