 The new MB keys are divided into three types(Cut by Bitting → HU64)，there is different key data on the different type which is shown on the picture 1.


Analysis: Please observe the red box in the picture,where the values are 580(HU64), 450(HU64-2),380(HU64-3).The three values represent the distance between the 10th Bitting and key tip.You can choose the appropriate cutting option according to the original key.(the larger the value,the smaller the slope)
