With a method for the production of a grinding tool, a tool base body is provided, which configures a three-dimensionally shaped adhesive sur-face by application of a bonding agent. The tool base body is positioned in a way that the adhesive surface is arranged in an electrostatic field, be-tween a first electrode and a second electrode. Into the electrostatic field, abrasive grains are introduced, which, due to the electrostatic field, move towards the adhesive surface and adhere to same. The grinding tool produced in this manner has a three-dimensionally shaped abrasive grain layer. The production of the grinding tool is simple, flexible and economical. The grinding tool has a randomly shaped abrasive grain layer and can be applied in a manifold manner with a high cutting performance and a long service life.

An abrasive tool can include a bonded abrasive including a body and a barrier layer bonded to a major surface of the body. The body can include abrasive particles contained within a bond material. The barrier material can include a metal-containing film. In an embodiment, the barrier layer may further include a polymer-containing film. In another embodiment, the barrier layer may include a biaxially oriented material. The abrasive tool may be formed such that the barrier layer is formed in-situ with the formation of the bonded abrasive.

A grinding element consists of a disk-shaped main body and blades formed as a unit therewith, wherein the main body and the blades are made of sintered hard material. An opening passing through the main body is arranged immediately in front of each blade with respect to a direction of rotation of the grinding element about a center axis. Each blade has a rake face that is partially cylindrical with a rake angle α=0° or partially conical with a rake angle α≠0°.
