Please see all photos as part of item' s description.
One of the most common methods of tapping in use today on CNC machines is “rigid tapping” or “synchronous feed tapping.” A rigid tapping cycle synchronizes the machine spindle rotation and feed to match a specific thread pitch. Since the feed into the hole is synchronized, in theory a solid holder without any tension-compression can be used.
However the problem with this is that in actual practice it is impossible for the machine to exactly match the pitch of the specific tap being used. There is always a slight discrepancy between what the machine is doing and the actual pitch of the tap. If a solid holder is used, this discrepancy is detrimental to tap life and thread quality because extra axial forces are exacted on the tap.
If a tap holder with tension-compression float is used, tap life and thread quality can be dramatically improved, because these extra axial forces on the tap are eliminated.
