Abstract: A rotary tool holder includes a shank having a flange, a tapered outer surface, and front and rear contact portions. The tapered outer surface corresponds to the tapered bore (53) of a spindle, and flexible circular cantilevers are provided at one or both contact portions such that a free end of the cantilevers expands radially due to centrifugal force to maintain contact with the tapered bore. The shank (50) can be formed from an inner member (58) and a sleeve disposed thereover, in which portions of the sleeve form the circular cantilevers. The circular cantilevers can also be formed by a cavity created in the shank. Alternatively, instead of circular cantilevers, the shank of the tool holder can have a taper which is optimized for a certain speed, wherein the taper of the shank has a first taper at rest and a different, optimized taper at a desired speed.

Abstract: A cutting insert for metal working operations has an insert core with a pair of cutting portions (324,334) having cutting tops extending therefrom such that a toolholder having a pocket to accept such a core is suitable to accept different cutting insers having a common core plus different cutting portions. As a result, for example, an 80° diamond, a 55° diamond and a 35° diamond cutting insert may all be utilized within a common toolholder. The invention is also directed to a toolholder that will accept such a variety of cutting inserts.

Abstract: An adjustment device (10) comprises a first portion (16) and a second portion (18). The first (16) and second (18) portions are adjustably engaging one another. The adjustment device has an overall length that is adapted to be adjusted by adjusting the first (16) and second (18) portions relative to one another. The overall length is adapted to be adjusted to vary a distance between the drill motor (116) and the work piece. Another embodiment of the invention comprises a slip fit member (20) and a threaded member (22) opposite the slip fit member. The adjustment device has an overall length that is adjustable to vary a spatial relation between the drill motor and work piece. Yet another embodiment of the invention comprises a drill motor (116), a support, and an adjustment device (10). The adjustment device (10) comprises a slip fit member (20) and a threaded member (22) spaced apart from the slip fit member. One of the members is engageable with the drill motor (116) and the other member is engageable with the support. The adjustment device has an overall length that is adjustable to vary the spatial relation between the drill motor and the support.

Abstract: A toolholder and insert cartridge are disclosed in which an insert cartridge holds multiple, similarly-shaped inserts in a face-to-face relation in a storage chamber. The insert cartridge has means thereon for dispensing individual inserts one at a time and can be adapted to be held and moved by a robotic arm or a reciprocal moving holder. A toolholder having an insert pocket with a movable insert seat therein is utilized with the insert cartridge. A reciprocably movable drawbar moves the insert seat in the toolholder pocket back and forth so as to clamp and unclamp a cutting insert.

Abstract: Disclosed is a milling cutter in which there is a cutter body having a plurality of insert pockets with each of the pockets having a back wall. There is also an indexable insert having opposed top and bottom surfaces joined by a peripheral wall to form a polygonal body when viewed in plan. The peripheral wall on each side of the insert forms a cutting edge at the juncture of one of the top and bottom faces and a clearance face on each side of the insert joins a peripheral wall and the other of the top and bottom faces. The milling cutter further comprises means for holding the insert in the pocket so that one of the top or bottom surfaces abuts the back wall.
