Why this set stands out

This is not a generic router kit. The Freud 98-308 three-piece configuration is purpose-built for French door construction, focusing on robust mortise-and-tenon joints and precise mullion/muntin alignment. The tenon-length versatility means you can tailor joints to your specific door thickness and wood species, reducing the risk of warping or loosening over time. The integrated mortising capability aligns with the profile bits to produce authentic, ready-to-assemble joints for true divided-light doors or convincing simulated divisions when paired with grills.

Ideal use cases

Perfect for woodworkers and door shops building custom Full Lite or True Divided Lite French doors for interiors or exterior applications. Ideal for projects where authentic light diffusion and classic styling matter, or for hobbyists seeking professional-grade results in a single, cohesive bit set.

Practical tips for best results

Plan your mullion pattern before routing, and start with scrap lumber to dial in tenon length and mortise fit. Verify grain direction and wood movement considerations for your chosen species, then move to your final stock. When assembling, ensure precise alignment of rails, stiles, mullions, and muntins to achieve a clean, professional look with strong structural joints.
