摘要： A cutting tool includes a base body and a cutting head at least partially disposed within a modular pocket of the base body. The modular pocket is formed by at least one wall section removably attached to the base body. In one variation, a non-removable portion of the base body also forms part of the modular pocket. In another variation, the modular pocket is formed by two removable wall sections on opposite sides of the modular pocket. In yet another variation, the removable wall sections include a clamping portion to exert a downward force on the cutting head to enable mounting the cutting head in the modular pocket using an interference fit.

摘要： A boring tool includes a coupling portion, a shank, and a cutting portion. The shank further includes a torsion release neck, having a smaller diameter cross section than a first end of the shank and a second end of the shank, a first transition to the first end of the shank, and a second transition to the second end of the shank. A torsion release neck has a lower polar moment of inertia than other portions of the boring tool so that it may guide torsional loading and shear stresses in the boring tool away from the cutting and coupling portions to improve the durability of the boring tool as a whole.

摘要： An orthopedic screw extractor device including a shaft, an end portion about a first end of the shaft for securing to a handle, and a screw extracting tip about a second end of the shaft opposite the first end. The screw extracting tip further includes a generally frustoconical shape having a side at an angle of about 5 to 15 degrees relative to a longitudinal axis of the screw extracting tip. The screw extracting tip further includes first, second and third screw threads and first, second and third flutes circumferentially spaced about the screw extracting tip and extending across an entire length of the screw extracting tip. Each of the screw threads has a lead of about 0.07 to 0.12 inches, a pitch of about 0.02 to 0.04 inches, a thread angle of about 40 to 50 degrees, and a depth of about 0.01 to 0.02 inches.

摘要： An apparatus is specified that comprises a rotary tool, wherein the rotary tool extends along a longitudinal axis and in an axial direction, wherein the rotary tool comprises a body, a cutting insert and a clamping rod, wherein the body has a shank on the rear-facing end, for clamping into a bracket, wherein the clamping rod extends through the body in the axial direction, wherein the clamping rod is adapted on the front-facing end to attach the cutting insert, wherein the clamping rod extends rearward towards the shank and can be actuated by means of a tool to attach the cutting insert to, or to detach the latter from, the body, wherein the clamping rod comprises an access hole arranged such that the clamping rod can be actuated while the rotary tool is clamped in the bracket. Further, a method for attaching or detaching a cutting insert on such an apparatus is specified.

摘要： A drill head is rotated about a center axis. The drill head includes: a mounting surface that is an end face in a direction of the center axis; a tip surface that is an opposite surface to the mounting surface in the direction of the center axis; an outer peripheral surface continuous to the mounting surface and the tip surface; a cutting edge extending from the outer peripheral surface toward the center axis in the tip surface; a flute that is formed on the outer peripheral surface and extends spirally around the center axis from the tip surface to the mounting surface; and a thinning surface continuous to the tip surface and the flute. The tip surface includes: a first flank surface continuous to the cutting edge; and a second flank surface located on a side opposite to the first flank surface with the flute interposed therebetween.

摘要： The helical tunneling device is a tool for tunneling along helical or spiral paths. Further, the tool may be used as a fixation device along helical/spiral paths, for connecting different surfaces or joints. Furthermore, the device includes associated instrumentation needed for creating such a helical path. In one embodiment, the device uses a woven flexible shaft in a helical tube to transmit rotational motion to a cutting tool. The helical tube may then be rotated independently to advance the cutting tool along a helical trajectory. In another embodiment, the device may advance helically into the created tunnel to engage, couple, and fix the relative positions of both bodies through which a continuous helical tunnel is created. Thus, the helical tunneling device is a simple and efficient tool that may be beneficial for wood working, orthopedics, metal manufacturing etc.
