A handle is coupled to an industrial machine tool, along with a method of operating the industrial machine tool via the handle. The handle comprises a housing, a first switch, and a second switch. The housing includes a first side, a second side, a top end, and a bottom end, the first side facing toward the industrial machine tool and the second side facing away from the industrial machine tool. The first switch actuates a float mode for the industrial machine tool, the float mode being a mode in which movement of a moveable portion of the industrial machine tool is power assisted for an operator of the industrial machine tool. The second switch actuates a machining portion, coupled to the moveable portion of the industrial machine tool, to perform a machining process on a workpiece.

The invention relates relates to a clamping system for clamping an object (1), in particular for clamping a cutting tool in a machine tool, comprising an accommodating bore (4) for accommodating the object (1) to be clamped, a threaded bore, which extends in the wall of the accommodating bore (4) transversely to the longitudinal axis (12) of the accommodating bore (4), and a clamping screw (6), which can be screwed in the threaded bore in order to selectively clamp or release the object (1) in the accommodating bore (4) in accordance with the screwing position of the clamping screw (6). The invention further relates to an intermediate element (9), which is arranged between the clamping screw (6) and the object (1) such that the clamping screw (6) touches the object (1) to be clamped (1) not directly, but rather indirectly by means of the intermediate element (9). According to the invention, the threaded bore is preferably arranged eccentrically in relation to the accommodating bore (4).

A cutting tool includes a cutting head and a tool shank, each having an axial abutment surface. One of the two includes a coupling pin, while the other includes a pin receptacle and a clamping through bore that opens out to the pin receptacle. The coupling pin has an engagement groove and the pin receptacle has an engagement ridge. The coupling pin is received into the pin receptacle. The cutting head and tool shank are releasably attached together by a fastening member that passes through the clamping through bore and acts on the coupling pin so that the engagement groove abuts the engagement ridge and the axial abutment surfaces on each part abut each other.

Damping elements for tool chucking systems for damping vibrations and shocks that occur during machining in the case of force-fitting clamping of tools in a tool receptacle or on the tool itself. At least one damping element consisting of a shape memory alloy having a mechanical effect is provided in a tool chucking system or on the tool itself, such that the damping element provided in the chucked state in the force flow of the chucked elements is present in a reversible and hysteresis-dependent state by way of a mechanical force action and the associated crystalline conversion via the pretensioning of said damping element and leads to dissipation of mechanical energy. The mechanical energy to be damped is a cyclical vibration or represents a non-cyclical overload which is transmitted in the form of shocks.

The invention relates to a tool holder on a drill transmission for tubular drilling tools having at least two different diameters, wherein the holder is equipped with a hollow-cylindrical recess and with at least one radially oriented locking bolt which is installed in the wall of the hollow-cylindrical recess and which engages in a corresponding opening in the drilling tool, wherein there is at least one further hollow-cylindrical recess which is complementary to one of the different drilling tools.

A power tool adapter for both standard drills and impact drivers includes a shank or drill coupler including a head, a neck or clip retainer integrally connected to the head, and an extender integrally connected to the clip retainer; a drill bit locker integrally connected to the drill coupler and specifically integrally connected to the extender, and a sleeve engager integrally connected to the drill bit locker. The power tool adapter is configured to simultaneously hold or engage a drill bit and a torque sleeve.

In one aspect, tool holders employing axial sleeves and dampening elements are described herein. Tool holders described herein define a central longitudinal axis and comprise a tool holder body having a connector portion and a holder portion. The connector portion is structured to engage a rotary machine and the holder portion is disposed opposite the connector portion and has an inner diameter surface comprising a plurality of axial grooves. Tool holders described herein further comprise a tool receiver structured to receive at least a portion of a cutting tool, the tool receiver having an outer diameter surface comprising a plurality of axial grooves. The tool receiver is mounted in the holder portion so as to align the axial grooves of the inner and outer diameter surfaces and define axial sleeves filled with dampening elements.

There is a demand for a cutting insert capable of machining a workpiece under a wide range of cutting conditions. The cutting insert has a first portion, and a second portion protruding from a front end of the first portion. The second portion has an upper surface, a cutting edge, a rising surface, and a connecting surface having a recessed curved surface shape. The rising surface is located closer to the first portion than the upper surface, and is inclined upward with increasing distance from the upper surface. The connecting surface is located between the upper surface and the rising surface, and is connected to the upper surface and the rising surface. In a cross section having a bisecting line of a first corner, a virtual extended line of the upper surface and a virtual extended line of the rising surface intersect at an acute angle.

A tool connector includes a main body, an adapter, a first engaging member and a sleeve. The main body includes a driving end portion and a connecting end portion. The main body has a first receiving hole extending along the axial direction and a second receiving hole communicated with the first receiving hole. The adapter is non-rotatably disposed within the first receiving hole and includes a through hole configured for a tool head to be disposed therethrough. The first receiving hole, the second receiving hole and the through hole respectively have a first, a second and a third cross-sectional profiles being non-circular. The second and the third cross-sectional profiles are identical in shape and coaxially arranged. As viewed in the axial direction, at least one geometric feature of the second cross-sectional profile corresponds to at least one geometric feature of the third cross-sectional profile.
