Is the angle of ISO handle the same as that of BT handle?

1. The ISO tool handle standard refers to the standard formulated by the International Organization for Standardization (ISO). In October 1946, leaders from 25 national standardization bodies met in London to discuss the establishment of the International Organization for Standardization (ISO), which is short for International Organization for Standardization. The meeting unanimously adopted the ISO charter and rules of procedure. On February 23, 1947, ISO came into operation. The central office of ISO is located in Geneva, Switzerland. China is both the initiator and the first member country.


2, BT tool shank: Taper shank shank (with manipulator gripping slot) for machine tools of machining centers manufactured by Japanese standard MAS403; ST means taper shank shank (without manipulator gripping slot) for machine tools of numerical control machines manufactured according to GB3837.


The angles of ISO tool holder and BT tool holder are different, as are the angles of professional machine tools and custom tool holders. Below is a comparison of the taper shank sizes of ISO shank and BT shank.
