Abstract
A cutting tool is provided which comprises a tungsten carbide body or core (2) to which is soldered, brazed or otherwise bonded at least one strip of tungsten carbide (3) that is ground to form a cutting edge or blade. A tough non-vibrating core is thus provided for use with a very hard blade separately replaceable. A method of forming the body or core (2) involves forming a pre-sintered preform, grinding one or more flutes in the preform and subsequently hardening the preform into a fully sintered state ready for use to receive one or more cutting blades.
