Good product

Size: 11 Holes

Works well for the must part. I ended up buying a different style bit collar stop because the one provided wasn't solid enough for me. Might be a personal preference

Awesome tool

Very easy to use, only issue I had was the location pin was a bit tight. Chucked it in the drill and polished it up with a scotch-brite and it worked perfectly. The end to end symmetry made it easy to move from one side to the other. Good price as well!
