The workpiece retaining device 10 includes a core member 32 that is round and that comes into contact an inner perimeter face of the retained portion 110 of the workpiece 100, a pressing member 33 that presses an outer perimeter face of the retained portion 110 of the workpiece 100 to an inner side in a radial direction, and an aligning member 44 that, upon a pressing force from the pressing member 33 acting thereupon, allows the core member 32 to move in the radial direction, in accordance with a magnitude and a direction of the pressing force.

A method and rivet apparatus comprise a rivet block, the rivet block comprising a rivet block, a pin bore, and a rivet feed bore. The rivet block is comprised of a top end and a bottom end. The pin bore includes a top end and a bottom end and is disposed within the rivet block. The pin bore extends from the top end to the bottom end of the rivet block and guides a rivet pin that slides downward within the pin bore to push a head of a rivet into a workpiece. The rivet feed bore includes a top end and a bottom end and is disposed within the rivet block. The rivet feed bore extends from the top end to the bottom end of the rivet block, accepts the rivet at the top end of the rivet feed bore, and guides the rivet to the bottom end of the rivet feed bore. The rivet feed bore intersecting the pin bore between the top end and the bottom end of the pin bore at an oblique angle.

A cutting tool assembly includes a tool shank having a coupling opening, and an insert holder having an insert body to which an insert is coupled and detachably attached. A coupling protrusion protrudes from one surface of the insert body and is detachably coupled to the tool shank. Located on the coupling protrusion are a tapered contact portion which comes into contact with the coupling opening and provides a fixing force to fix the insert holder to the tool shank, and a contact surface at a rear end of the tapered contact portion which couples to a fastening member.

A fixing device for fixing a boring bar on a material-removing machine includes a reducing sleeve with a hollow profile arranged on a front face which faces away from a machine chuck. The boring bar is received in an interior of the hollow profile. An end region of the boring bar projects from the hollow profile and carries a cutting tool. The hollow profile has a wall arranged between the interior and an exterior of the hollow profile. The wall has a first thickness and a second thickness. The first thickness is less than the second thickness. The first thickness is established at a side of the fixing device where the cutting tool projects radially from the boring bar. A longitudinal axis of the hollow profile is parallel to and at a distance from the axis of the reducing sleeve which is coaxial with the interior of the boring bar.

The insert holder includes a forwardly located insert mounting portion that includes an insert receiving recess which extends along a recess axis. The insert holder includes a fastening member through hole opening out to the insert receiving recess. The insert receiving recess includes an insert orientation projection. The fastening member through hole has a through hole angular extent about the recess axis. The insert orientation projection has an insert orientation projection angular extent about the recess axis. The insert orientation projection angular extent at least partially angularly overlaps the through hole angular extent about the recess axis.

A method and rivet apparatus comprise a rivet block, the rivet block comprising a rivet block, a pin bore, and a rivet feed bore. The rivet block is comprised of a top end and a bottom end. The pin bore includes a top end and a bottom end and is disposed within the rivet block. The pin bore extends from the top end to the bottom end of the rivet block and guides a rivet pin that slides downward within the pin bore to push a head of a rivet into a workpiece. The rivet feed bore includes a top end and a bottom end and is disposed within the rivet block. The rivet feed bore extends from the top end to the bottom end of the rivet block, accepts the rivet at the top end of the rivet feed bore, and guides the rivet to the bottom end of the rivet feed bore. The rivet feed bore intersecting the pin bore between the top end and the bottom end of the pin bore at an oblique angle.

An upper drill tool including a central chuck, an upper component, a lower component and a coupling assembly. The central chuck has a chuck base and a chuck structurally configured to retain a drill bit. The upper component is attached to the central chuck and has a lower stop surface. The lower component has a central body and an outer ring that threadedly engages the central body, with the outer ring having an upper stop. The coupling assembly is configured to facilitate the slidable movement of the lower component from a first orientation wherein the upper stop is spaced apart from the lower stop surface and a second orientation wherein the upper stop is in abutting engagement with the lower stop surface, with the first orientation and the second orientation defining a stroke.

A method and rivet apparatus to rivet a workpiece comprises an upper riveting portion and a lower riveting portion. The lower riveting portion comprising a fixed base, support member, and a pin assembly. The pin assembly comprises a center pin, a forming pin, a first biasing member, an outer shroud, and a second biasing member. The center pin pushes against a tail of a rivet to deform the tail of the rivet. The forming pin, fixedly coupled to the support member, pushes against the tail of the rivet to deform the tail of the rivet. The first biasing member, disposed below the center pin, biases the center pin through the forming pin and away from the support member. The outer shroud encircles the forming pin and the center pin. The second biasing member, disposed below the outer shroud, biases the outer shroud away from the support member.
