摘要： A pipe extractor removes a broken pipe from a connector or a fitting. The pipe extractor comprises an upper shaft mechanically coupled to a lower shaft where the lower shaft is further mechanically coupled to cutting insert, the cutting insert comprises a stop, a shaving edge and a cutting edge. A user can affix the upper shaft to a drill and engage the drill to turn the cutting insert causing the cutting edge to remove the broken pipe from the connector or the fitting. The cutting insert is further affixed to a guide such that the guide can ensure that the cutting edge is properly aligned with the broken pipe.

摘要： A bit for removing a broken fastener comprises a tip from which extend two or more notches separated by traction or biting surfaces formed from two-sided frusto-conically-shaped regions. The surfaces are bounded on one side by a nonlinear cutting edge and on the other side by a non-cutting edge and are configured to cut into the fastener when the bit is rotated in a direction opposite to the fastener's direction of engagement. Specific embodiments include configurations where the cutting edges extend at different angles with respect to the bit axis, where the biting surfaces comprise a plurality of serrations, and where the cutting edges are separated by flutes which spiral along a longitudinally extending periphery of the bit.
摘要翻译：用于去除破损的紧固件的一点包括一个尖端，从该两个或多个凹口延伸两个或更多个凹口，该两个或多个凹口由由双侧截头圆锥形区域形成的牵引或咬合表面分开。表面在一侧由非线性切削刃限定，另一侧由非切削刃限定，并且当钻头沿与紧固件的接合方向相反的方向旋转时被构造成切入紧固件。具体实施例包括其中切割边缘相对于钻头轴线以不同角度延伸的构造，其中咬入表面包括多个锯齿，并且其中切割边缘由沿钻头的纵向延伸周边螺旋形的凹槽分开。

摘要： The drill bit comprises a cutting blade formed at one end of a shank. The cutting blade has a pair of cutting shoulders that extend inwardly from the outer sides of the blade toward the bit axis. A tip having converging sides that create a point extends from the shoulders. The cutting edge of each shoulder is beveled with respect to the plane of the face of the blade. A flute is provided on the leading portion of each blade face adjacent the cutting edges. Each flute is a smooth curve that creates a substantially uninterrupted recess on each face of the blade that facilitates chip removal, increases the drill rate and lowers the power required to drill a hole. A non-stick coating may be applied to the blade to further facilitate chip removal.
