A cutting tool fastener having a rotation axis and configured to secure together, and establish a fluid path between, two cutting tool members, while also accommodating angular and pivotal displacement between the two. The fastener comprising a head with at least one head opening for emitting fluid, and a body which extends from the head and has a body opening for receiving fluid to be emitted via the head opening. The head has a spherical head abutment surface with a bottom spherical seal surface zone. At least a portion of the spherical head abutment surface faces the body, and the head opening opens out to the spherical head abutment surface. The bottom spherical seal surface zone is axially located between the body and the head opening.

A quick grip pocket hole jig system is presented having a support section having a clamp support, an end stop and a back stop. A clamping assembly is connected to the support section having a clamping rod that extends through the clamp support. A drill guide carrier having a drill guide assembly is connected to the clamping rod on a forward side of the clamp support. A clamp body having a trigger and a release mechanism is connected to the clamping rod on a rearward side of the clamp support. The clamp body is a quick grip clamp body that facilitates quick gripping of a workpiece positioned within the support section. The clamping assembly includes a return spring and a release mechanism such that when the release mechanism is actuated the drill guide carrier and the drill guide assembly are automatically moved to a non-clamping position.

A positioning clamp for spray-coating of a wheel trim ring includes a lower base plate, a circular bracket, an upper base plate, a plurality of guide rods, a plurality of sliding support parts and a distance adjusting mechanism. The distance adjusting mechanism is configured to drive the plurality of sliding support parts to approach a central position along the guide rods and to move away from the central position along the guide rods. According to the positioning clamp for spray-coating of the wheel trim ring, the position of each sliding support part can be adjusted to adapt to wheel trim rings of different sizes. Therefore, the positioning clamp for spray-coating of the wheel trim ring can replace a large number of positioning clamps of different sizes, and has the advantages of being simple in structure, stable and reliable in positioning, low in manufacturing cost and the like.

A clamping device for clamping a workpiece or a tool or, more specifically, a tool holding fixture in a machine part of a machine tool includes a tension rod slidably mounted within the machine part; a clamping set movable by the tension rod between clamped and released positions; a tension spring dedicated to the tension rod so as to generate the pull-in force of the clamping set; and a release mechanism, by which the clamping set can be moved against the force of the tension spring into the released position by the tension rod. To make possible effective clamping at optimum force, the tension spring is clamped between first and second rod parts of the tension rod. The second rod part can move relative to the first rod part, and, as the clamping set moves into the released position, is compressed on both ends by the release mechanism by moving the two rod parts in opposite directions.

A tool coupling extends along a longitudinal axis and has a first component, a second component, and a clamp for fastening the first component to the second component. The first component has a male clamping portion, the second component has a female clamping portion, and the clamp is located in an inner cavity of the second component. The male clamping portion has a first abutment region located axially rearward of a first plane perpendicular to the longitudinal axis, the inner cavity has a second abutment region located axially forward of the first plane, and the first and second abutment regions face towards the first plane. In a fastened state, a clamp first engagement region of the clamp makes clamping contact with the male clamping portion's first abutment region, and a clamp second engagement region of the clamp makes clamping contact with the inner cavity's second abutment region.

Tool system 1 comprising a tool holder 2 that has an insert seat 17 for receiving a cutting insert 6, and comprising a clamping element 4 that has an opening 26 for receiving a clamping means 15, an interface 30 being arranged between the tool holder 2 and the clamping element 4, and channels for the purpose of cooling by means of a fluid being arranged in the tool holder 2 and the clamping element 4, and a sealing means 31 being arranged in the region of the interface 30.

A cutting tool for turning and/or boring operations can include a holder, a replaceable insert supported by the holder in a cutting position, and a clamp releasably coupled to the holder and configured to bear against the insert to retain the insert in the cutting position. The clamp can be releasably coupled to the holder without a threaded fastener. The cutting tool can include a retention mechanism for releasably connecting the holder and the clamp, the retention mechanism having alternate locked and unlocked states.

A skiving apparatus is provided for at least partial removal of the surface of an least approximately tubular body having a center axis, in particular of a plastic pipe, comprising a clamp assembly having a center axis and at least one clamp member for clamping the skiving apparatus to the tubular body, a skiving assembly comprising a skiving arm unit, a skiving knife arrangement disposed at a first end of the skiving arm unit, and a skiving arm support that connects the clamp assembly to the skiving arm unit. The skiving arm unit is connected by its first and second ends to the skiving knife arrangement and the skiving arm support and is pivotable in the common plane with the center axis of the clamp assembly in such a way that the skiving knife arrangement keeps its orientation relative to the center axis of the clamp assembly in every pivoted position of the skiving arm unit. A clamp assembly as a tool holder for a tool such as a skiving tool is also provided, for machining an approximately tubular body having a center axis, in particular a plastic pipe, having a center axis, a mandrel disposed coaxially with the center axis of the clamp assembly, and at least one clamping device disposed on the mandrel and directed substantially radially outwards.

A pipe lathe includes a shaft; a cutting head supported on the shaft for movement with the shaft; a mandrel positionable on an outboard end of the shaft for supporting the shaft along a machining axis; and a first external pipe clamp and a second external pipe clamp, the first and the second external pipe clamps supported for external pipe engagement substantially concentrically about the machining axis. Multiple spaced apart engagement sites provided by the mandrel within the pipe and the external pipe clamps on an outer surface of the pipe support the pipe in a linear and centered position for machining by the cutting head, even when the pipe is non-linear, flexible and possibly with a cross section that is on-circular.

A cutting tool fastener having a rotation axis and configured to secure together, and establish a fluid path between, two cutting tool members, while also accommodating angular and pivotal displacement between the two. The fastener comprising a head with at least one head opening for emitting fluid, and a body which extends from the head and has a body opening for receiving fluid to be emitted via the head opening. The head has a spherical head abutment surface with a bottom spherical seal surface zone. At least a portion of the spherical head abutment surface faces the body, and the head opening opens out to the spherical head abutment surface. The bottom spherical seal surface zone is axially located between the body and the head opening.
