An auger bit for cutting holes. The auger bit includes a body made of a first material. The body has a first end, a second end configured to be coupled to a power tool, a flute, and a longitudinal axis extending centrally through the body. The auger bit also includes a cutting tip made of a second material different from the first material. The cutting tip is coupled to the first end of the body. The cutting tip includes a first shoulder having a first spur, a first main cutting edge, and a first side cutting edge. The cutting tip also includes a second shoulder opposite the first shoulder and having a second spur, a second main cutting edge, and a second side cutting edge. The cutting tip further includes a center spur positioned between the first shoulder and the second shoulder and on the longitudinal axis.

A cutting tool including a body, a blade, a feed shaft, and a locking member. The body defines an axis and is adapted to be received by a spindle of a power tool. The blade is removably supportable on the body and rotatable about the axis for cutting a workpiece. A feed shaft is removably supportable in the body and rotatable about the axis for engaging a workpiece, the feed shaft being mountable in the cutting tool to engage and at least partially restrain the blade. The feed shaft further includes an opening transverse to the axis. The locking member is engageable with the body and with the opening in the feed shaft. Advancement of the locking member into the opening tightens both the blade and the feed shaft to the body.

A motor drive for a rotary medical device having at least one seal-set which comprises a bore defining bearing, a motor having an output shaft, a flexible shaft, having a diameter smaller than the bearing's bore, being power transmittingly and concentrically connected to the output shaft, a seal, defining a bore that is smaller than the flexible shaft's diameter, being mounted adjacent to the bearing with its bore concentric relative with the bearing's bore, wherein the flexible shaft passing through the bearing's bore which sufficiently deflects it to align it with the second bore to interferencingly fit through it and hydraulically seal it.

Systems and methods of the present disclosure relate generally to facilitate performing a task on a surface such as woodworking or printing. More specifically, in some embodiments, the present disclosure relates to mapping the surface of the material and determining the precise location of a tool in reference to the surface of a material. Some embodiments relate to obtaining and relating a design with the map of the material or displaying the current position of the tool on a display device. In some embodiments, the present disclosure facilitates adjusting, moving or auto-correcting the tool along a predetermined path such as, e.g., a cutting or drawing path. In some embodiments, the reference location may correspond to a design or plan obtained from obtained via an online design store.

A method and apparatus for manufacturing an aircraft structure. A drivable support may be driven from a first location to a second location to bring the drivable support together with at least one other drivable support to form a drivable support system. A structure may be held in a desired position using the drivable support system.

A method for implementing machining operations for a workpiece. Pre-existing hole locations for temporary fasteners in the workpiece requiring a clamp-up force for performing the machining operations to form holes in the workpiece is identified. A set of the pre-existing hole locations is determined from the pre-existing hole locations that results in an optimal path for performing the machining operations on the workpiece taking into account clamp-up force specifications for the workpiece. The optimal path has a near-minimum distance. An ordered sequence for performing the machining operations to form the holes at hole locations is determined that has the optimal path. Robotic control files that causes robotic devices to perform the machining operations using the optimal path is created. The robotic devices are operated using the robotic control files to form the holes in the ordered sequence using the optimal path that takes into account the clamp-up force specifications.

A method of processing a workpiece comprises identifying processing locations on the workpiece, drilling a first hole at one of the processing locations using a rotary drive, sensing a flow of fluid while drilling, generating an operation signal based on the flow, comparing the duration interval of the operation signal to a predetermined temporal value, and drilling a different hole at a different processing location based on the duration interval and the temporal value.
