   In fact I have made my own split collets for sizes like #7 and #21 to   
   slip inside the native R8 spindle collets.  I have also moved the head   
   off to one side and hung the part out past the table, clamped to the   
   face of a right angle plate.  This adds a couple feet to the height of a   
   part I can drill.  I prefer not to move the head around if I don't have   
   to though.  Hence why I use collets sometimes instead of the Tegara   
   integrated shank drill chuck.   
      
   --------------------------------   
   Since I modify Grade 5 and 8 bolts fairly often I made a 3/8"-16 3-part   
   split collet to clamp the threads straight while machining the usually less   
   straight shank and head. The best version has O rings in grooves at the ends   
   that keep it together and let a bolt or threaded rod be pushed instead of   
   screwed in. Less commonly modified sizes have solid threaded bushings to   
   allow turning a root depth pilot and tapered aligner on the ends, a great   
   help outdoors where a dropped screw can be lost in grass / leaves or slide   
   into the gutter.
