This is the largest dovetail bit I've found for my 1/2" router bits. I use it to build my new massive workbench from extremely hard and dense Massaranduba wood. Folks, she cuts butter like a hot knife! While I don't have long experience with this particular cutter, my experience with this particular manufacturer leads me to believe it will remain great for a long time to come. I would highly recommend this particular heavy duty cutter. You will need both a workbench and furniture with solid wooden panels.
