Freud 98-307 3-Piece French Door Roundover Router Bit Set with 1/2-Inch Shank

The Freud 98-307 3-Piece French Door Router Bit Set mills precision full-lite and true-divided-lite glass passage doors across 1-3/8-inch interior and 1-3/4-inch exterior solid hardwoods and softwoods. Engineered with an architectural Roundover edge profile and unlimited-length tenon milling geometry, this matched 1/2-inch shank set produces deep, interlocking structural joints capable of supporting heavy insulated glass panels. Premium TiCo High-Density Carbide cutters coated in heat-dissipating red Perma-SHIELD work in tandem with a dedicated #16-120 mortising bit to rout clean muntin and mullion joinery in table-mounted router setups without cross-grain tear-out.

Best Used For:

  • Exterior French Door Construction: Milling 1-3/4-inch thick solid mahogany, oak, and Douglas fir structural door frames with deep mortise-and-tenon connections for heavy exterior glass.
  • True Divided Lite Mullion Joinery: Routing narrow muntin bars, glass stops, and interior mullion intersections using the matched mortising cutter without edge splintering.
  • Custom Interior Glass Passage Doors: Shaping classical Roundover stile and rail profiles on 1-3/8-inch interior doors for historical residential renovations.

Key Performance & Safety Features

  • Unlimited Tenon Length Capability: Specialized rail and stile geometry allows woodworkers to mill extended structural tenons of any length for superior joint shear strength.
  • Dual Door Thickness Versatility: Precision-engineered step geometry machines standard 1-3/8-inch interior and robust 1-3/4-inch exterior door thicknesses with equal accuracy.
  • TiCo High-Density Carbide Cutters: Micro-grain titanium cobalt formulation maintains razor-sharp cutting edges through abrasive hardwoods and dense resinous softwoods.
  • Perma-SHIELD Non-Stick Coating: Proprietary red fluoropolymer coating shields tool bodies from frictional heat buildup, gumming, and corrosive pitch accumulation.
  • Dedicated #16-120 Mortising Bit: Specifically designed to rout matching mortises for divided light glass mullions and muntin intersections.
  • Heavy-Duty 1/2-Inch Shanks: High-tensile steel shanks eliminate rotational vibration and bit deflection in high-horsepower table-mounted router setups.

Pro-Tip: Mill extra-long tenons on your door rails by removing the slot cutter on the rail bit and using a dedicated coping sled on your router table; deeper tenon mortises provide the shear resistance needed to prevent glass door sagging over time.
