That drill guide can also be used in conjunction with the head to drill out sheared off head studs as per Illistrated in Woodrow. In Woodrow it shows a pilot hole being drilled first with a similar guide but for a smaller drill. However if you use the larger drill first just to mark the centre the pilot hole can be drilled without a guide then going back to the larger guide to accurately drill out the stud keeping it straight.
