What are the common used domino sizes???

[PeterK]

Getting serious about ordering one of these toys - I mean tools. Seems that I can get far more dominos by ordering the needed cutters and bags than by ordering the package as I surely don't need another systainer. Mostly work in 3/4-1" material with some 2X2 stuff. I know I will find more and more uses for this tool but don't want to spend money on a size ya'll never use. Any input appreciated. Thanks so much.

6 x 30 are the most common one's used in my humble shop.  You simply won't believe how strong those little guys are. Mostly to join plywood together for cabinets.  I can see a use for the larger ones in outdoor furniture I have plans for.

I agree with Howard on 6mm ones. By far, they are the most used in my shop as well.

I also use 6x40mm most often, but find 5x30 and 8x50 useful to a lesser extent. If I need larger sizes, I make my own. Usually 32x10x50/56mm or larger.
