Abstract: The invention proposes a handle for a screwdriver or a similar tool, which over a significant part of its length has a cross-section in the form of an approximately regular pentagon. The corner or angle sections are rounded with a radius of curvature, whose centre is in the longitudinal axis of the tool handle. The corner sections formed by the curved part of the cross-section have a different width over the handle length. The shape of the flattenings does not follow the shape of the handle contour.

Abstract: A fly-cutter milling machine for the simultaneous milling of a plurality of grooves (12) in rotating workpieces (2) by means of a fly cutter (3) which protrudes radially outwards on a rotating tool holder, the speed of revolution of the tool holder and the speed of revolution of the workpiece being in a ratio which is determined by the number of grooves of the workpiece. In order to obtain optimum operation with the groove profile precisely adapted to the tool cutting edge, the rotation of the workpiece (2) is briefly interrupted at the moment of the maximum depth of plunge of the fly cutter (3) by a phase of reduced speed of the workpiece (2).

Abstract: A device for connecting a tool to a mechanical drive contains as the coupling element a spring washer coupling or clutch, which is made in one piece from metal and at least in the rotation direction has a limited resilience. Use is made thereof for preventing torque peaks in the case of a sudden deceleration of the tool, e.g. if a screw strikes a wood surface.

Abstract: A machine for simultaneously milling several grooves in rotating workpieces by means of a rotating one-toothed milling tool, whereby the rotational speeds of the milling tool and workpiece stand in a ratio determined by the number of grooves, and whereby the milling tool in the longitudinal direction from the free end of the workpiece--freely-cutting--is plunged in the workpiece which is advanced in the longitudinal movement. The tool carrier is pivotable about an axis lying perpendicularly to the rotational axis of the workpiece such that the rotational plane of the cutter tool is able to be brought in an acute angle relative to the rotational axis of the workpiece.
