Abstract

A tool component, in particular a cutting insert, essentially consists of self-bonded abrasive particles and a network of mutually communicating, dispersely distributed pores. This tool component is made by directly bonding a mass of abrasive particles to one another to give a self-bonded object, using a sinter aid material at high pressures and temperatures. The object formed under the action of the high pressures and temperatures contains self-bonded particles, i.e. particles directly bonded to one another, and is penetrated by the sinter aid material, for example cobalt or cobalt alloys. The sinter aid material is then removed, for example by immersing the object into aqua regia. It has been found that, by removal of essentially all the sinter aid material, an abrasive particle object is obtained which shows a substantially improved resistance to thermal decomposition at high temperatures.
