Flush trimming is so much easier with the right tool. I typically use a veneer saw for straight trimming but I've also been using this spiral router bit for tricky veneers and curved edges. The spiral down-cutting action presses the veneer (and chips) toward the substrate which practically eliminates tear out on wood veneer.

It is the downward cutting action that differentiates this type of bit from standard flush cutting bits where the cutting action is lateral. These razor sharp bits are the most affordable I've found.

Not for use with plastic laminate or PSA veneers.
