 The article examines the forecasting performance of the cutting tool equipped with interchangeable plates of carbide oxide ceramics (A2 – mixed ceramic), by definition porous ceramic tool material affecting its cutting properties. Set correlation of porosity ceramic tools from electrical resistivity removable ceramic plates. Cutting tools having larger electrical resistivity values and, respectively, smaller porosity percentages should be used for machining the most precise components of machine part blanks, since their performance will be better than that of the tools whose ceramic bits have small electrical resistivity values. Based on the established correlation selects ceramic plates for the required machining conditions.
