In a method for producing a grinding tool, a tool base body (4) is provided that forms a three-dimensional adhesive surface (24) by application of a binder (23). The tool base body (4) is positioned such that the adhesive surface (24) is arranged in an electrostatic field (E) between a first electrode (5) and a second electrode (6). Abrasive grains (8, 9) are introduced into the electrostatic field (E), which abrasive grains move, as a result of the electrostatic field (E), to the adhesive surface (24) and adhere there. The grinding tool produced in this way has a three-dimensional abrasive grain layer (25). The production of the grinding tool is simple, flexible and economical. The grinding tool has an abrasive grain layer (25) of any shape and can be used in a wide range of applications with a high cutting performance and a long service life.

GRINDING TOOL AND METHOD FOR MANUFACTURING A GRINDING TOOL OF SAID TYPE
A grinding tool comprises a base on which a plurality of grinding blades (8) is arranged. The grinding blades (8) each include a substrate (16) and abrasive (22) that is bonded to the substrate (16) by means of a binder (23). In order to increase the service life and the total amount of material that is removed, the grinding blades (8) are reinforced by a filler resin (25). Since the grinding blades (8) are reinforced, their cyclic deflection about a zero position caused by workpiece machining operations is reduced, thereby preventing excessive wear of the grinding blades (8).

GRINDING TOOL, AND METHOD FOR PRODUCING SUCH A GRINDING TOOL
The invention relates to a grinding tool (1) comprising a support body (1) and a plurality of grinding lamellae (8) arranged thereon. The grinding lamellae (8) each have a base (16) having a grinding means (18) arranged thereon. For the purpose of removing a used grinding lamella portion (22), the base (16) has at least one target weakening region (21) on a side that faces away from the grinding means (18). As a result of the removal of used grinding lamellae portions (22), the grinding tool (1) has an improved grinding behavior. The grinding properties remain intact until the grinding tool (1) has worn out completely. By removing the used grinding lamellae portions (22), fine dust particles are avoided.

GRINDING ELEMENT, METHOD FOR PRODUCING THE GRINDING ELEMENT, AND INJECTION-MOLDING TOOL FOR CARRYING OUT THE METHOD
The invention relates to a grinding element (1) comprising a disk-shaped main body (25) and blades (19) formed as a unit with the main body, wherein the main body (25) and the blades (19) are formed of sintered hard material. An opening (26) passing through the main body (25) is arranged immediately in front of each blade (19) with respect to a direction of rotation of the grinding element (1) about a center axis. Each blade (19) has a rake face (20), which is partially cylindrical with a rake angle α = 0° or partially conical with a rake angle α ≠ 0°.

A milling burr for use in handheld machines has a shank and a cutting member of hard metal which is rigidly connected to said shank. The cutting member is provided with cutting teeth which extend in a first direction of twist. The cutting teeth are divided in cutting tooth portions by rows of tooth dividers extending in a second direction of twist. The cutting tooth portions and the tooth dividers are arranged one behind the other when seen in the peripheral direction in such a way that an overlap occurs in an in each case alternating manner when seen in the peripheral direction.
