A cutting element, which is configured for the machining of a non-metallic composite material composed of a matrix and particles held together by the matrix, has a flank face, a rake face and a cutting edge which is coated with an edge coating and via which the flank face and the rake face are connected to one another, with which the non-metallic composite material can be machined in an improved fashion. The cutting edge within a cutting edge section thereof is curved in such a way that the cutting edge immediately beneath the edge coating in a section in a section plane that is perpendicular to the cutting edge has, at every point of the cutting edge section, a local radius of curvature which is greater than or equal to 10 μm and less than or equal to 80 μm.

A wood drill includes a clamping portion for connecting, for conjoint rotation, to a tool fitting of a portable power tool, and a head portion which is provided with a centering geometry. The clamping portion is formed at a first end, remote from a workpiece, and the head portion is formed at a second end, close to a workpiece, of the wood drill. The clamping portion is connected to the head portion via a shank portion. A maximum outside radius of the head portion is greater than a maximum outside radius of the shank portion. The head portion has at least one main lip with at least two stages for introducing a bore with a predefined inside radius into a workpiece. An outside radius of a main lip base is less than 60%, preferably less than 50%, of an outside radius of the head portion.

A cylindrical drill bit includes at least one set of circumferential cutting edges positioned at a circumference of the drill bit; the circumference is centred to a longitudinal rotational axis; each set of circumferential cutting edges includes at least two circumferential cutting edges; and the at least two circumferential cutting edges have a mutually different radial distance from the longitudinal rotational axis.

A boring tool may include a coupling portion which may be at an end of the boring tool, a shank operably coupled to the coupling portion, a cutting portion operably coupled to the shank and a feed screw which may be operably coupled to the cutting portion at an opposite end of the boring tool from the coupling portion. The cutting portion may further include a first paddle, a second paddle, and a third paddle. Each paddle may each comprise a paddle body, defined by a leading edge and a lateral edge. The paddle bodies may be disposed equiangular around a perimeter of the cutting portion. The leading edge may extend away from a longitudinal axis of the boring tool in a direction substantially perpendicular to the longitudinal axis. The lateral edge may extend away from the leading edge in a direction substantially perpendicular to the leading edge.

The present invention surrounds a gouge for use in woodturning, particularly in the fabrication of wood bowls, wherein the gouge is configured to provide longer reach with decreased deflection. The decreased deflection allows safer and more efficient woodturning process, resulting in better quality woodturning products. The gouge includes an inner cutting profile which is offset upward from the center of the outer profile, thus providing more structural rigidity when extending the tool from a tool rest and into the concavity of a bowl being turned.

The present invention is for a handle system for a woodworking tool to allow both the safe stowage of a woodworking tool and the operational use of the woodworking tool. A handle configured with a first collet receiver and a second collet receiver interconnected at either end of a generally hollow longitudinal handle. The collet receivers are adapted for receiving and interconnecting with a collet, and the collet is configured to receive and hold a woodworking tool therein. The first collet receiver enables the stowage of the woodturning tool within the longitudinal handle, and the second collet receiver enables the use of the woodturning tool in a working configuration which constrains the woodturning tool extending axially away from the longitudinal handle.
