Hello,

Just checking my understanding of these tools.

Does a grub screw hold the shank of the end mill and a drawbar hold the morse taper in a socket ?

Is the grub screw sufficient to stop the end mill "walkin" out of the holder ? Does the grub screw simply grip a flat on the end mill ?

I suppose you could also have the grub screw pushing a plug in front of it with a curve cut into the nose that matches the radius of the shank-hole and there fore sits snugly against the shank ?
