Fresa grande de painel côncavo com cortador traseiro – Whiteside 5920E

Switching to this bit eliminated a whole setup step for me—the back cutter and front reveal happen in one pass, and that 1/4" tongue is dead on every time. I've run maybe a dozen panels through it so far and the edges are clean enough that I don't need to touch them up before glue-up.

The 1/4" tongue comes out perfectly every time, which saves me from having to make multiple passes. I love how the back cutter eliminates an extra setup step for the cabinet doors. Clean edge with zero tear-out on the red oak I ran through it.

The back cutter on this bit saved me a separate setup step and the tongue came out a perfect 1/4” on my first test cut. It’s pricey, but for cabinet doors the precision is absolutely worth it.
