so run out is <.001 4'' from the Albrecht chuck i checked it a few times my dial goes down to .00005 the rod i used is -.005 , +.0015 so well within tolerance for the rod. the chuck is so smooth and grabs so perfectly really nice chuck. the manual stop for depth is pretty crap kinda a after thought it really is crap mine came bent so it just kinda rubs when moving the quill up and down im going to remove it is usable, but yeah its just that the lowes porter cable i have the manual depth is better.
