A dado stack will make a dado, or groove that runs across the grain. Host David Thiel explains how dadoes can be essential to cabinetry work.
A closer look at a dado.

Making repeated cuts with a single blade (figure A), one right beside the other can make a dado without a dado stack. This is time-consuming, but cost-effective since new tools are not required.- A dado stack consists of two undersized blades that fit on the outside, with chippers in between them. The chippers come in two and four wing designs in different widths. Use shims when your cut needs to be precise. Shims are available in various widths to provide precise adjustment (figure B).
A wobble dado is another type of dado cutting blade (figure C). This is a blade that moves from side to side while turning. This is a single blade technique that will cause tears and ridges in the dado, so it's not useful if you need a smooth dado. Use a height gauge to set the height of the blade.A dial-a-width dado is similar to a stack dado, and will provide a smooth cut. It has a cam system that clicks the blades (figure D) into place without having to move the shims. It does not create tearing and ridges in the wood like a wobble dado will.
