If you're using 3/4" thick stock for your door panels you'll want to use these Back Cutter router bits. They cut a quick rabbet in the back of 3/4" thick door panels allowing you to keep the face of your raised panel flush with the face of the rails & stile door frame. You'll be left with a 1/4" thick tongue on your door panel which will fit perfectly into the 1/4" groove made by your stile router bits.

Ryan ★★★★★ Oct 22, 2026

Swapped out my old router bit for this one and the difference is night and day—the rabbet cut came out perfectly clean on the first try. Running it through 3/4" stock for door panels was effortless, and the face stayed totally chip-free. Exactly what I needed for a quick, precise back cut.

I was worried about chips on the face of my door panels, but this back cutter's sharp carbide tip leaves a super clean rabbet every time. The 1/2" shank fits securely in my router table without any wobble. Definitely speeds up my workflow for cabinet doors.

Finally, a bit that lets me rabbet the back of door panels without adjusting my entire setup. Cuts cleanly through 3/4" stock and leaves a smooth surface.
