PCT No. PCT/SE88/00625 Sec. 371 Date Jul. 31, 1990 Sec. 102(e) Date Jul. 31, 1990 PCT Filed Nov. 17, 1988 PCT Pub. No. WO90/05607 PCT Pub. Date May 31, 1990.A cutting tool equipped with a tool state detector which comprises temperature sensors and conductors which are placed on the tool. The invention is characterized in that two or more temperature sensors (10-13) are placed on the tool (1) at mutually different distances from the tool cutting edge (3), so that the temperature distribution in the tool (1), at least at the cutting edge (3) and its immediate vicinity, can be established from electric signal emitted by the sensors (10-13), and that at least some of the sensors are so placed that one or more of the sensors will be worn away in successive sequence as the tool (1) wears. The temperature sensors (10-13) are preferably thermoelements.
