Generally few drill presses are to be counted upon for accuracy, especially this type; the accuracy is inherent in the tooling (drills, reamers, and whatever. I will say, that there are limits to how much slop is allowable; some of these have a way, such as a split quill housing to take up on some excessive clearence, and spindle plain bearings can be replaced. Case in point, I had a 4ft arm Cincinnati Bickford radial drill that had so much wear to the spindle quill, that it was nearly impossible to drill a hole to a center punch mark within (nearly) 1/16" due to the fact that when you used a point or center drill to pick up the mark, when pressure was applied to the center drill, the spindle would move sideways; you had to compensate by starting the hole to the side of the mark so it would move over to the intended location. The final cure was to line bore the spindle /gearbox housing and make a new (oversize) quill. Later sold it and bought the proper cure, a American Hole Wizard 5' arm radial.
