ABT40 Holder Taper and Both Faces Are in Contact With the Spindle. As a result, the spindle and Holder Act as a single unit. This allows a Higher "Radial Rigidity", hence we get a good surface finish and Dimensional Accuracy While Machining Also Low Vibration at higher speeds, which increases tool life.
