This arm features a semi-automatomatic tap lubricator system and a size TWO quick change chuck. Five free size one and size two chucks are inlcluded with this order, as well as a 30 day free trial and a three year warranty. 
 
For this arm to tap horizontaly and vertically, the multi-position head needs to be ordered along with the arm. This is an accessory that cannot be added after the arm is built. Thank you.
