摘要： One non-limiting aspect of the present disclosure is directed to a multi-piece spade drill head for a spade drill, wherein the spade drill includes an elongate body portion and a cutting portion removably secured to an end of the body portion. The multi-piece spade drill head includes at least two insert pieces, each piece including a cutting edge. The at least two insert pieces are configured to be removably secured to the body portion of the spade drill adjacent one another and with the cutting edges of the insert pieces aligned to together form a cutting edge on an end of the spade drill.

摘要： A cutting tool insert having a controlled contact clearance behind the cutting edge which limits flank wear and allows more coolant near the cutting edge further allowing an increase in surface speed, feed rates, and tool life. The controlled contact clearance surface provides a first wear zone and a second wear zone, the first wear zone generated during operation of the drill insert allows the flank wear distance to grow from zero to the distance from the cutting edge to the controlled contact clearance surface, the second wear zone keeps the flank wear distance substantially constant until the controlled contact clearance surface is substantially worn away.

摘要： The throw-away drill includes a cutting edge portion (31) for cutting a work and shank portion for fitting to a predetermined position of a cutting tool, and in which, the cutting edge portion is detachably and mechanically coupled to the shank portion (32). The cutting edge portion and the shank portion have complementary fitting portions and slits are formed in either one of the cutting edge portion and the shank portion. When the cutting edge portion and the shank portion are fitted to each other, the opposed surfaces to these slits (34,39) move away from each other and undergo elastic deformation, so that the resulting elastic force fixes the cutting edge portion to the shank portion. Accordingly, screwing or the like is not necessary and the cutting edge portion and the shank portion can be coupled by mere press-in operation. Accordingly, working efficiency can be improved during the assembly process. A surface coated ultra-hard alloy is used as the material of the cutting edge portion, and steel as the material of the shank portion. Therefore, the cutting edge is excellent in wear resistance, adhesion resistance and heat crack resistance and the shank portion a relatively low-coat throw-away drill. @(56pp Dwg.No.6/23)@

摘要： The invention relates to a drill consisting of a substantially cylindrical holder (10) with a drill tip (12). A cutting insert fitted in the groove having two main cuts (26', 26'') with forwardly adjacent cutting surfaces (32', 32''). The holder (10) has two bores (20', 20'') in a radial plane (R) of the drill, each of which is in the region of a rear surface (30', 30'') of the insert (25) and opens into a groove side (18', 18''). The longitudinal axes (24', 24'') of the drillings (20', 20'') run at an acute angle to the groove side (18', 18'') and the adjacent rear surface (30', 30'') of the insert (25).

摘要翻译：抛弃钻头包括用于切割工件和柄部分以用于装配到切割工具的预定位置的切割边缘部分（31），并且其中切割边缘部分可拆卸地和机械地联接到柄部分（32））。切削刃部和柄部具有互补的配合部，狭缝形成在切削刃部和柄部中的任意一个上。当切割边缘部分和柄部彼此嵌合时，这些狭缝（34,39）的相对表面彼此远离并且发生弹性变形，使得所产生的弹力将切割边缘部分固定到柄部一部分。因此，不需要螺纹连接等，仅通过压入操作即可将切削刃部和柄部联接。因此，在组装过程中可以提高工作效率。使用表面涂覆的超硬合金作为切削刃部分的材料，以及作为柄部的材料的钢。因此，切削刃具有优异的耐磨性，耐粘附性和耐热裂纹性，并且刀柄部分具有相对较低的涂层抛掷钻头。 @（56pp Dwg.No.6 / 23）@。

摘要： A throw-away tipped drill, in which: a pair of chip disposal grooves are formed on the outer peripheral surface of a drill main body which rotates around an axial line, At an end portion of said drill main body, a concave groove shaped tip attachment seat is formed which, along with connecting to said pair of chip disposal grooves, also opens at an end surface of said drill main body. To said tip attachment seat, a throw-away tip of approximately a flat plate shape, upon an edge of which a pair of cutting edges are formed, is fitted by the pair of internal side surfaces of said tip attachment seat being mutually brought towards one another by a clamp bolt which is screwed into an end portion of said drill main body so that it crosses said tip attachment seat.
Along with a pair of outer side surfaces of said throw-away tip respectively confronting a pair of internal side surfaces of said tip attachment seat, a pair of raked surfaces, which are portions of said pair of outer side surfaces of said throw-away tip which face towards the forward rotational direction of the drill, respectively, open into said pair of chip disposal grooves.
By forming concave portions on the internal side surfaces of said tip attachment seat which do not contact against the outer side surfaces of said throw-away tip, pressure portions are created and are positioned more to the rearward direction of the rotational direction of the drill than the central axial line of said clamp bolt. When said clamp bolt is tightened up, said pressure portions press against the outer side surfaces of said throw-away tipped drill.
