Read before you buy!!!
Jacob's used to make top quality drill chucks and they were the Porsche for the machining world. That is no longer the case. Run out is absolutely horrible on all sizes of super chuck. The first chuck I received looked like someone used a Dremel to grind the i.d. of the jaws and the total run out was measured at conservative .013. Harbor freight hand drills have less run out. This was returned and a replacement sent. The 2nd chuck was measured on different size dowel pins with a T.I.R of .011. I thought maybe the arbor could be a problem so I used 4 different arbors and all measurements were identical. I tried contacting Jacob's but they simply don't care. The quality of every chuck 14n---18n etc I have purchased is Chinese junk even through the price demands quality. Save yourself and purchase a Rohm or Albrect chuck.

Worth the price EASY
Really like the compact size and the fact that I can chuck up a bit too small to see clearly! Ball bearing chuck is smoooooth.
