该欧洲标准规定了用于具有圆柱形和锥形柄的铣削刀具的柄部强度的夹紧装置处给定的偏心率的最大速度的确定。它还指定了工具的标记。安装在心轴上的钻孔工具应被视为安装在刀柄上的刀具。 该欧洲标准补充了EN 847 1，也适用于切割直径小于16 mm的刀柄

This European Standard specifies the determination of the maximum speed for given eccentricity at clamping devices for the shank strength of milling tools with cylindrical and taper shank. It also specifies the marking of the tool. Bore mounted tools which are mounted on an arbor should be considered as a shank mounted tool. This European Standard complements EN 847 1 and applies also for shank tools with a cutting diameter of less than 16 mm.
