Abstract: A sintered cemented carbide body comprises tungsten carbide as hard material and a metallic binder which contains cobalt (Co), chromium (Cr) and copper (Cu). The cobalt is present in a proportion of 7.0 to 14.0% by weight in the sintered cemented carbide. The copper proportion is from 0.05 to 3.8% by weight and the chromium proportion is from 0.2 to 1.9% by weight, in each case based on the overall weight of the sintered cemented carbide body. The cemented carbide body is advantageously used for cutting titanium and titanium alloys, cast iron and steel.

Abstract: The invention relates to a cutting tool made of ceramics, cermet or cemented carbide and including a rake face, a flank face and a cutting edge at the intersection of rake face and flank face, as well as a multi-layered wear resisting coating including a layer which is made of aluminum oxide and deposited on a hard material layer, in which for avoiding an increase in the width of wear mark, with simultaneous retention of the resistance to cratering of the rake face, the aluminum oxide layer of the coating is removed on the flank face and the underlying hard material layer is exposed at least in portions. The aluminum oxide layer of the coating is removed on the flank face preferably by means of laser beam treatment.
