A cutting tool may include a base member and a diamond layer located on the base member. The cutting tool may include a first surface, a second surface, and a cutting edge located in at least a part of a ridge line which the first surface intersects with the second surface. The diamond layer may be located in at least a part of the first surface, at least a part of the second surface, and at least a part of the cutting edge. A maximum height in the cutting edge may be smaller than a maximum height in the first surface. The maximum height in the cutting edge may be greater than a maximum height in the second surface.

A cutting tool part includes a cutting portion. The cutting tool part further includes a plurality of guide pads projecting radially outwards from the cutting portion. At least the cutting portion and the plurality of guide pads are made through additive manufacturing, the plurality of guide pads being integrally formed with the cutting portion in a unitary one-piece construction. A rotary cutting tool is provided having a cutting insert releasably attached to the cutting tool part.

The burnishing part includes: a mandrel; burnishing rollers; a frame; an adjustment member that presses the frame axially from one end thereof to adjust the axial position of the frame with respect to the mandrel; and an elastic member that is arranged axially on the other side of the frame to support the frame. The reaming part includes: a base part that is detachably attached to the mandrel; and machining blades that are formed integrally with the base part. This results in providing a combined machining tool that is capable of machining an inner peripheral surface of a workpiece having a smaller diameter, and a machining method using the same.

The device disclosed herein allows a user to maintain the outboard stabilator of a Blackhawk helicopter. The device, which comprises a kit, allows a user to remove damaged outdoor stabilator bushings from a Blackhawk. Upon removal, the device enables a user to install new outdoor stabilator bushings. Additionally, the device allows a user to ream the newly installed outdoor stabilator bushings so that the outboard stabilator may be reinstalled upon the Blackhawk and safely flown.

A tool system for machining a workpiece is provided having a cylinder-shaped retaining shank that has a cutting head holder on an end surface facing the workpiece, a drive mount on an end surface facing the drive, a cutting head having at least one cutting edge, a cutting head hub corresponding to the cutting head holder on the retaining shank, a tool coupling with a tool interface, and a coupling hub corresponding to the drive mount. The coupling hub or the cutting head hub have elevated areas, with contact surfaces, distributed in circumferential and longitudinal directions of the coupling hub or the cutting head hub. The contact surfaces make contact on support surfaces on the drive mount or on the cutting head holder on the retaining shank. The drive mount or the cutting head holder is permanently connected to the coupling hub or the cutting head hub by a joining material in intermediate spaces between the elevations.
