摘要： A tool holder includes a shank including a tool holder portion and a central bore for accommodating a cutting tool, and a first shrink fit sleeve disposed about the tool holder portion of the shank. An application of heat to the tool holder causes the tool holder portion and the first shrink fit sleeve to expand outwardly, and the removal of heat will cause the tool holder portion and the first shrink fit sleeve to contract inwardly to rigidly maintain the cutting tool within the tool holder by shrink fit. The tool holder may also include a second shrink fit sleeve disposed about the first shrink fit sleeve to provide increased torque capability.

摘要： A drill having a replaceable cutting head, modified to eliminate forces which would distort the pocket of the drill shank and otherwise concentrate stresses which would cause failure of the drill. The cutting head has a frustoconical depending connecting member received in a receptacle formed in the shank. In different embodiments, contact between the pocket formed in the shank and the cutting head connecting member is limited. In one embodiment, angle of drive surfaces is modified from prior art practice. In another embodiment, transition of at curved joints between vertical and horizontal surfaces is made more gradual. The drill preferably has flutes formed collectively by the shank and cutting head when assembled.
摘要翻译：具有可替换切割头的钻头，其被修改以消除将扭曲钻柄的凹坑的力并且另外集中将引起钻头故障的应力。切割头具有收缩在形成在柄部中的容器中的截头圆锥形的连接构件。在不同的实施例中，形成在柄部中的凹穴与切割头连接构件之间的接触受到限制。在一个实施例中，驱动表面的角度从现有技术的实践中被修改。在另一个实施例中，在垂直和水平表面之间的弯曲接头处的过渡变得更渐进。当组装时，钻头优选地由柄和切割头集体形成的槽纹。
