A couple of days ago I decided to retire my sacrificial drill press table insert
Actually just flipped it over
For most critical drilling I use a scrap of thin wood to back up the workpiece. That keeps the back of the hole from blowing out and splintering. Or, using forstners and brad points, I set the depth stop so just the point penetrates the backside and then I flip it and drill to get clean entry holes on both sides.
Still its unavoidable to end up drilling your table surface some. Sometimes you are too lazy to use a backer or its too awkward a cut.
I was dumb when I installed by DP table. I set the center of the insert under the center of the drill axis so all the damage occurs in one arc. If I had off set it by about an inch or 3/4 inch then the damage would be spread out more by rotating the insert.. But its too much trouble to change now. I would do it differently today.
Whats up with your guys DP tables? Mine is an older woodpecker low profile table, my quill raising arms are too long and hit the fence on most tables. The fence is a piece of t-track only 1/2" tall with stops; I do have a tall 4" fence with a cutout for the quill and the arms to get close to the table..
