Abstract: The invention relates to a cutting tool, in particular a milling tool, which comprises a tool body on which at least one cutting edge is provided. A coolant supply channel, from which at least one nozzle channel branches off fluidically, extends inside the tool body. The nozzle channel is configured to conduct coolant onto the cutting edge. A flow cross-section of the coolant supply channel is furthermore reduced in one flow direction.

Abstract: A lightweight cutting tool, such as a reamer, includes a front cutting body, a front cutting ring, a center tube, a rear cutting ring and a rear machine connection member. An arm assembly of the front and rear cutting heads includes one or more leading arms, one or more trailing arms and a cutting head supported by the leading and trailing arms. The leading arms and the trailing arms curve in opposite directions. To reduce weight and moment of inertia of the reamer, a cross-sectional area of the leading arms and the trailing arms is largest proximate the sleeve member and is smallest proximate the cutting head. In addition, the front cutting body, the front and rear cutting rings and the center tube may be made by additive manufacturing. Fluid can be transported entirely through the reamer to the cutting insert/workpiece interface and the guide pad/workpiece interface.

Abstract: A milling cutter (10), in particular a side milling cutter, is described, having a tool body (12), to which at least one cutting insert (14) is removably secured, said cutting insert being clamped by means of a movable clamping element (16) in the tool body (12) and comprising a cutting edge (18) pointing in the direction of rotation (R). The clamping element (16) clamps the cutting insert (14) from behind and is arranged on the rear side of the cutting insert (14) in the direction of rotation (R) of the milling cutter (10).

Abstract: A cutting insert made of cemented carbide and the use thereof for recessing or copy-turning, preferably at a high rotating speed. The cutting insert has at least one recess for insertion therein of a cutting body of a material other than cemented carbide, such as a ceramic material.

Abstract: A cutting insert made of cemented carbide and the use thereof for recessing or copy-turning, preferably at a high rotating speed. The cutting insert has at least one recess for insertion therein of a cutting body comprising a cutting material different from cemented carbide to form a firm connection, the cutting body having a cutting edge formed thereon. The cutting insert has high mechanical strength even with small dimensions in the high-temperature range because the cutting body comprises a ceramic cutting material and has a geometric shape at least a portion of which is congruent with the geometric shape of the recess. The abstract of the disclosure is submitted herewith as required by 37 C.F.R. §1.72(b). As stated in 37 C.F.R. §1.72(b): “A brief abstract of the technical disclosure in the specification must commence on a separate sheet, preferably following the claims, under the heading “Abstract of the Disclosure.
