Donut Hole Drill Guide Hobbyist
Donut Hole Drill centering guide for the hobbyist. This item is used for self centering drilled holes in shades. It may be used with a 1/2" hand held drill or a drill press. Donuts are wear parts and will probably need to be replaced after each hole is drilled. See options for purchasing additional donuts.
Comes with Black donuts for the 45 mm standard socket hole and White donuts for the 30 mm candelabra socket hole.
See "The Hole Thing" for the professional version. If you are going to be doing lots of lighting products, we'd recommend " The Hole Thing" mounted into a drill press.
