摘要： A gun-drill (20) comprises a cutting head (22) detachably secured to a shank (24), having a common longitudinal axis (A) and comprising mating peripheral surfaces. A shank coupling portion (78) comprises a forwardly tapering shank fixation surface (86) is formed at a front end of the shank, and a cutting-head coupling portion (58) comprising a forwardly tapering cutting-head fixation surface (68) is formed at a rear end of the cutting-head. Both the shank and the cutting-head coupling portion extend over a peripheral coupling angle ϕ of more than 180°. The shank and the cutting-head are assembled by positioning the cutting-head leading face in front of the shank trailing face, slidably inserting the cutting-head coupling portion into the shank coupling portion laterally to the axis of rotation A and rotating the cutting-head relative to the shank in a direction opposed to the direction of rotation R so that the cutting-head coupling portion and the shank coupling portion interlock co-axially.

摘要： The invention relates to a drill (4) as well as to a device and a method for drilling bores into workpieces (3), a periodically effective radial force (19) being applied to the boring head (5) of the drill (4). The boring head (5) of the drill (4) comprises a blade (52) that extends only across part of the diameter D (51) while being embodied with a lateral, V-shaped chip-removing groove or bead (59) and a channel (12) encompassing an outlet (56) in the boring head (5) for delivering a drilling fluid (9). A recess (63) that reduces the cross section of the boring head (5) in relation to an enveloping cylindrical outer surface (62) of the boring head (5) is configured between a first and a second cylindrical outer surface (64, 75) of the boring head (5) on a side (61) of the boring head (5) which faces away from the bead (59).

摘要： A metal cutting drill includes a steel drill body, and a carbide insert (60) brazed therein. The drill body includes a front face (52) having a recess (54) formed therein, the recess radially overlapping a longitudinal axis of the drill body. The insert (60) is brazed in the recess (54) and includes a plurality of spaced-apart cutting edges (62,64,66,68) disposed on opposite sides of the axis. The cutting edges radially overlap during a drilling operation. One of the cutting edges (68) projects radially outwardly beyond a side face of the head, and another of the cutting edges terminates radially inwardly of the side face.

摘要： A drill bit (10), particularly for cutting deep holes in hard materials, includes a tubular shank (12) with a solid center (20) and diametrically opposed coolant conduits (14,16) which supply coolant to a tungsten carbide tip (32) located on one end of the tubular shank (12). Swarf and debris are carried by the coolant away from the cutting area and along swarf clearance channels (22,24) located along the exterior of the shank tube out of the borehole. The carbide tip (32) is brazed to the tubular shank (12) and is formed with a pair of angularly spaced tubular chambers (44,46) which communicate with the coolant conduits in the shank. One cutting edge (34.361 is provided on top of each chamber in the tip. A coolant hole (48) is formed at the top of each tubular chamber (44,46), behind the cutting edge (34,36). The coolant which emerges from the tip (32) flows to the space between the tubular chambers (44,46) and carries with it the swarf along the swarf clearance channels (22,24) defined by the shank out of the borehold.
摘要翻译：特别是用于切割硬质材料中的深孔的钻头包括具有固体中心和直径相对的冷却剂管道的管状柄，其将冷却剂供应到位于管状柄的一端的碳化钨尖端。切屑和碎屑被冷却剂从切割区域沿着沿着柄管外部的切屑间隙通道排出钻孔。硬质合金刀头钎焊到管状柄上，并且形成有与刀柄中的冷却剂管道连通的一对角度间隔的管状腔室。一个切削刃设置在尖端的每个腔室的顶部。在每个管状室的顶部，在切割边缘之后形成冷却剂孔。从尖端出来的冷却剂流到管状室之间的空间，并沿着由轴限定的切屑清除通道将其切割出钻孔。

摘要： A tool coupling arrangement for drills and reamers includes tool and shank portions with respective tool and shank axial stoppers. An at least partially cylindrical tool coupling end of the tool portion is located within a longitudinal through forward bore portion in the shank portion, and being coupled therein via an elongated coupling member located further inwards in the shank portion and comprising axially opposite member coupling and pulling ends. The forward bore portion has front and rear sub-portions and a bore recess which is located therebetween and extends radially outwardly. In a locked position, the tool axial stopper abuts the shank axial stopper. The tool coupling end abuts the front and rear sub-portions. And the member coupling end is wedged between the tool coupling end and the bore recess.
