Agree totally with getting the accessory kit.
Another great addition is the Domiplate from Seneca. It screws onto the base of the Domino to perfectly position the tool for either 3/4" or 1/2" plywood or other wood with those dimensions.
You probably know the Domino needs a good strong vac to connect to its dust port.
The Domino is a wonderful tool, but it requires good technique to get good results.
Watch Halfinchshy's YouTube videos. The videos cover calibration and technique. He has "tricks" that will save you time and reduce scrapping valuable wood.
Practicing on scrap wood is a good idea before you tackle a project.
