Klassischer Nut- und Feder-Fräsersatz – Whiteside 6006

The ball bearing guides made guiding this bit set along the cabinet doors incredibly smooth, and one pass really does cut both the joint and panel groove perfectly. I’ve used cheaper sets before, but the precision here saved me a ton of sanding time.

Finally got around to running these on my router table and the ball bearing guides tracked the fence perfectly, even on some curved edges I threw at them. The one-pass cut on the raised panel groove saved me a good chunk of time versus my old two-bit setup.

The interlocking design is spot-on—both the stile and rail profile plus the raised panel groove come out in a single pass, which saved me a ton of setup time. The ball bearings glide smoothly along the fence, and the cut edges are clean enough that I skipped sanding on most joints.
