This paper will investigate the use of a new sensor device for detection of acoustic emission through fluid for a drilling machine and for the machine center. Within the industry there has always been the need for a practical application of the sensor of AE through fluid to detect the cutting-process-related signals from the tool side. Amounting device which enables the sensor to be fixed close to the rotating multipoint cutting tool has been developed to meet this need. Thus, there is now a more practical method for detecting the tool fracture and tool wear of twist drills. Judgment of tool life by use of a method for quantifying by the ratio of the event count and oscillation count per unit time allowed to the judgment of tool life was carried out very accurately from the above transaction, and the evaluation method for quantifying tool life by the ratio of the event count and oscillation count was found effective.
