In a method of producing a tool component a plurality of fibres is formed into a bundle. Each fibre has a core comprising a mass of ultra-hard abrasive particles or precursor to said ultra-hard abrasive particles and optionally a second phase, and a coating comprising a mixture of carbide particles and particulate binder metal. After extruding the bundle of fibres, the bundle is severed transverse to its length to produce a layer 24. The layer 24 is placed on a surface 26 of a substrate 28 and the layer 24 and substrate 28 are subjected to elevated temperature and pressure conditions at which the ultra-hard abrasive particles are crystallographically stable. The composition of the core and coating may be interchanged in the method.
