英文摘要：

This study proposed a novel method of measuring microdrill＇s CWT （Core Web Taper） based on the measurement of single flute＇s CWT, and a new synthetic evaluation of CWT is presented. The advantages of the new method are experimentally proven to be lower cost, higher efficiency and more reasonable compared with the current measurement method.
