1-1/8in Forstner Drill Bit for Arcade Pushbutton Holes
2017-12-21 · Mark the hole center, use a small bit (say 1/16 or 1/32) to drill all the way through at the center. Now use the forstner from the top, drill down about halfway. Flip the piece and finish the hole from the other side, using your center hole to align the forstner. Presto! Both sides will be completely clean.
