Abstract

A sawing wire (100,110,120,130) with abrasive particles (20) is presented wherein the particles (20) are partly embedded in said a metallic core (14) and partly in said an organic binder layer (30). The advantage of the wire (100,110,120,130) is that the application of a metallic binder layer (30) can be avoided. Metallic binder layers add to the cost of a fixed abrasive sawing wire and in many cases pose health and safety problems which can be avoided by the use of an organic binder layer. Moreover the advantages of a good fixture of the abrasive particles in the metallic wire are maintained. Different embodiments are presented with different degrees of embedment into the metal wire.
