Recent advance in high-speed cutting materials have focused on reinforcingalumina with different carbides and nitrides in order to improve hardness and fracturetoughness, this composites materials use in cutting tools application. The present studyconcert on properties of cutting tools made by Al2O3 reinforcement by Mg-PsZ. Theadded weight fractions from ZrO2 are (15% , 20%). The materials cold-pressed at (5, 7,10) ton, at (1400, 1500, 1600 Co) in two hours. The result shows increasing in hardnessand densities values of specimen with the increasing the mixing percent also, there is asignification enhancement of specimen properties with increased temperature andpressure, the approperte temperature is 1600 Co with pressure 10 ton.
