This is an adapter for use with a circular sawing jigsaw on a Skil 800w model. With this adapter you can make perfectly round holes. Simply use the included guide, put it in upside down, add this adapter, drill a center hole, attach it and go around in perfect circles. Measure the radius of the hole from the center of the centering bolt to the outer edge of the blade. The adapter is perfectly aligned with the cutting edge and perfectly separated from the surface of the material. When using the adapter, tighten it slightly in the center hole for maximum precision. Don't forget to tighten the guide with the screws on the jigsaw. Used with m5 screws, washers and nuts or wing nuts as in the example.
