摘要： Two-piece drill bits and methods of manufacturing same provide a preferably hexagonal shank, and a drill portion having a proximal end inserted into an axial hole in a distal end of the shank. In a preferred embodiment, at least part of the area adjacent the proximal end of the drill portion is knurled. Alternative embodiments have wings, polygons, tapers or other irregular shapes, or combinations of same. A variety of means may be employed to mechanically capture the drill portion in the shank.

摘要： A tool device in which a torsion tool such as a drill bit is provided with oppositely disposed flanges of such size and shape that the jaws of the chuck press against the sides of the flanges while all three jaws tend to engage and clamp the shank of the tool, so that the chuck may be manually tightened and loosened. Where the jaws of the chuck are not cut away but form a solid cylinder when engaged with each other, the flanges can be of such size and shape to be engaged by two of the jaws while allowing all three jaws to engage the shank of the tool without substantial flexing of the flanges. Where the jaws are cut away so that their clamping portions do not meet when the jaws are brought together, the flanges may be more flexible to ensure that all three jaws engage the shank of the tool.
摘要翻译：一种工具装置，其中诸如钻头的扭转工具设置有相对设置的这种尺寸和形状的凸缘，使得卡盘的夹爪抵靠凸缘的侧面压紧，同时所有三个钳口倾向于接合和夹紧工具，使卡盘可以手动拧紧松开。当卡盘的爪不被切除但在彼此接合时形成实心圆柱体时，凸缘可以具有这样的尺寸和形状，以与两个夹爪接合，同时允许所有三个爪与工具的柄接合没有凸缘的实质弯曲。当钳口被切掉时，使得当钳口被夹在一起时它们的夹持部分不相遇，则凸缘可以更灵活，以确保所有三个爪与工具的柄接合。

摘要： A METHOD, WHEREIN A TWIST DRILL OR A SIMILAR TOOL HAVING ONE OR MORE HELICAL FLUTES OR GROOVES IS PRODUCED FROM A ROD-SHAPED BLANK HAVING A CORE WITH A SUBSTANTIALLY CIRCULAR CROSS SECTION FROM WHICH ONE OR MORE CIRCUMFERENTIALLY SPACED RIDGES OR RIBS EXTEND RADIALLY AND AXIALLY. WHEN TWISTED, THE CORE OF THE BLANK CONSTITUTES A COLUMNAR CIRCULARLY CYLINDRICAL CORE OF THE TOOL, AND IN CONNECTION WITH THE CYLINDRICAL SURFACE OF THE CORE THE SIDE WALLS OF THE RIDGES OR RIBS DEFINE THE FLUTES OR GROOVES OF THE TOOL.

摘要： A holder for a cutting tool, comprising a body having a first channel for receiving a stem portion of the cutting tool. The body has a second channel intersecting with said first channel. The holder further comprises a plunger (13) to be inserted in the second channel, said plunger (13) having a third channel (14) the cross section of which at least partly overlaps with the cross section of the first channel when the plunger (13) is inserted into the body so as to enable the stem of the cutting tool to extend into the third channel (14) when the stem is inserted in the first channel. The holder (1) further comprises a mechanism (26) for locking the stem against movement relative to the body by means of the plunger. The invention furthermore relates to a cutting tool for use in such a holder and a cutting insert.

摘要： The invention relates to a tool system comprising an exchangeable rotary tool (1) for electric hand-held machine tools, preferably with a drill and/or hammer function, in particular for an electric hammer drill, and an electric drill, in particular a percussion drill. Said tool system also comprises at least two tool holders (15) that are embodied as tool fittings (17) that are associated with the hand-held machine tools and are different types (16, 22). The rotary tool (1) comprises an insertable shank (3) to be accommodated in the respective tool holder (15) of the hand-held machine tools, said shank having at least two driving fins (5) that are diametrically opposed and that extend along its longitudinal extension for rotational engagement. Said tool fitting (17) of a first type (16) is embodied as a positive fit fitting (18) and another tool fitting (17) of the second type (22) as a multi-jaw clamping chuck (23). The driving fins (5) have a width and a height such that, in the clamped state, they are at a lateral distance from the clamping jaws (24) of the multi-jaw clamping chuck (23).
