A C-shaped tool holder has a first leg and a second leg that is arranged opposite to the first leg, a connecting piece by which the first leg and second leg are connected with each other at a respective connecting end. An operating end of the first leg serves for fastening a punch in the direction of the operating end of the second leg, and an operating end of the second leg serves for fastening a die dome wherein an offset difference due to a gravity-caused offset between the operating ends of the first and second legs can be minimized by at least one compensating element which is arranged at one or more of the following elements: the first leg, the second leg or the connecting piece.

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.

A self-piercing riveting (SPR) system includes a top sheet and a bottom sheet. The top sheet is layered above the bottom sheet and are disposed between a die and a blank holder. The SPR system further includes a barrier disposed between the bottom sheet and the die, wherein the barrier is configured to reduce stress concentrations during formation of a joint between the top sheet and the bottom sheet. The barrier may has a thickness between 0.8 mm and 1.0 mm and is made from a cold formed or a dual phase steel alloy.

A setting unit and a method for setting a connecting element on a work piece. The setting unit has a hold-down clamp. A punch is displaceably mounted in the hold-down clamp, is drivable in a feed direction by way of a plunger and has a front punch head, and a punch sleeve which surrounds the punch head. The punch sleeve is movable together with the punch in the feed direction to a first stroke position. The punch head is movable relative to the punch sleeve to a second stroke position such that it is possible to carry out both a hole punching operation and a setting operation by way of the one punch in connection with the punch sleeve.
