Abstract: A method of manufacturing a metal bonded abrasive product such as a saw or drill segment or bead for a diamond wire is provided. The method includes the steps of providing a mixture of the metal, in particulate form, and the abrasive particles, cold pressing the mixture to the desired final shape at a pressure in the range 320 to 1500 MPa to produce a cold pressed product at a temperature in the range 900 to 1300.degree. C. under conditions which inhibit degradation of the abrasive particles and the particulate metal. The product, after free sintering, will generally have a relatively high porosity, for example, a porosity of 10 to 25 percent by volume.

Abstract: A coarse grained cemented carbide is produced by sintering a mixture of coarse grain carbide particles having an average particle size of at least 10 microns and a nickel binder in particulate form. The cemented carbide has particular use in the manufacture of a cutting element for a soft rock mining tool or road planing tool.
