Vパネルさねはぎルータービットセット – Whiteside 3374

Finally a tongue and groove set that actually fits 1/2-inch material without forcing it. The ball bearing guide ran smooth and clean through a full sheet of plywood with zero tear-out.

I've been cutting 3/4 inch plywood panels for a built-in cabinet and this two-piece set made the tongue and groove joints line up perfectly every time. The ball bearing guide keeps things tracking true, and the fact it handles up to 1-1/4 inch stock gives me room to use it on thicker projects later.

The ball bearing guide rides so smoothly that the joint comes out perfectly centered every time, and I’ve used it on oak and pine without any tear-out. Set the depth once and it handles the 1/2″ to 1-1/4″ range effortlessly, so I’m finally done fiddling with shims.
