A tool includes a parent body () and at least two cutting inserts () fastened directly or indirectly to the parent body (). A central clamping device () is configured to clamp the cutting inserts () in an oriented position relative to the parent body (). An assembly includes the tool () and a jig (), which can accommodate the tool () in such a way that the cutting insert () is located in a desired position on the tool () and can be clamped in the desired position by actuating the clamping device (). A method for fastening at least one cutting insert () to the parent body () includes fitting the parent body () with the cutting insert (); arranging the parent body () in a jig (); bringing the cutting insert () into a desired position; and clamping the cutting insert () in the desired position.

Tool and method for machining a workpiece, such as a milling tool, including at least one cutting insert and including a grinding wheel, for machining a workpiece, and the method thereof. The grinding wheel is axially extendable relative to a base body of the tool via fluid actuation from a cooling fluid supply. Additionally, cooling fluid is also provided to a grinding surface of the grinding wheel.

Milling cutter and a cutting insert for a milling cutter

Milling cutter (), which can rotate about a cutter longitudinal axis (A), comprises a sleeve-shaped shaft () provided with an inner lying chip evacuation channel (), which is arranged, in essence, symmetric to the cutter longitudinal axis (A), and with a suction opening (). The milling cutter also comprises a milling head (), which is held coaxial to the cutter longitudinal axis (A) and to the shaft () while being held on said shaft and which comprises, as cutting edges (), a face cutting edge () and a peripheral cutting edge (). At least one cutting edge () forms a positive rake angle ('Ya,&#x2032;Yr) on the periphery of the milling head (). The milling cutter () is particularly suited for machining light metals, especially for circular milling.

A method for supplying the working parts of a boring tool, in particular a drill, with a lubricant which both cools and lubricates the drill. A dispenser is connected directly or indirectly to the drill to enable lubricant to be fed to the working parts of the drill through at least one channel in the drill. A boring tool, in particular a drill, is also disclosed with a shaft, a cutter, at least one internal lubricant channel and at least one reservoir being fitted as a dispenser for the lubricant. The reservoir is directly or indirectly connected to the drill by mechanical connections and to the at least one lubricant channel to permit the passage of lubricant. In addition, a tool holder designed to hold the drill is disclosed. The tool holder has an internal dispenser for the lubricant. The dispenser is connected, when the drill is fixed in place, to the at least one lubricant channel in the drill to permit the passage of lubricant.

A drill is disclosed with a least one central channel for cooling-lubricant oil feed. The drill has a shaft with at least one flute extending in a spiral around the shaft axis. The oil, fluid, and gas is fed to the point of application of the drill through lateral outlet apertures which are joined to the at least one oil channel by connecting channels.

Rotary tool, in particular a drill

A diamond coated elongate rotary cutting member and method of making the same. The cutting member includes an axially forward cutting surface, a flute and a fluted land. The cutting member comprises a substrate with hard grains bonded together with a metallic binder. The substrate has a first substrate region that presents an irregular surface so as to define the axially forward cutting surface and the fluted land. The first substrate region contains relatively large hard grains near the surface thereof that are larger in size than the hard grains in the interior of the substrate. A diamond coating is on the surface of the first substrate region. The substrate has a second substrate region that defines the flute.
