The Freud/Diablo 99-001 2" door lip bit is a purpose-built solution for precise, professional door hinge rabbeting. Designed to work with table-mounted routers, it delivers a clean, accurate edge profile specifically for doors that use 3/8" rabbeted hinges.

In a single pass, this bit mills a 3/8" radius on the face of the door while simultaneously creating a 3/8" rabbet with a 7° bevel on the back to accept the offset hinge. The result is a matched, flush fit that minimizes fit-up time and maximizes hinge alignment accuracy.

Key features and benefits:

• 2" diameter cutting head provides stability and smooth results across the cut edge.
• One-pass operation creates both the face radius and the hinge rabbet/bevel, simplifying setup and workflow.
• 3/8" radius on the door face pairs with a 3/8" rabbet and 7° bevel on the back for consistent hinge alignment.
• Versatile material compatibility—designed to cut hardwood, softwood, plywood, and composites without changing bits.
• Reliable brand—part of the Freud/Diablo lineup known for precision woodworking tooling, crafted to hold its edge and deliver repeatable results.

Who should consider this bit? Interior door installers, cabinetmakers, woodworkers renovating or building prehung doors, and shop-based hobbyists who demand accurate hinge mortises and clean, professional edges. If your project requires offset hinges with a 3/8" rabbet, the 99-001 door lip bit ensures a precise fit and a polished appearance with minimal fuss.

Practical notes for best results:

• Use with a table-mounted router and secure workpieces to maintain altitude and edge guidance.
• Test on scrap material to dial in depth so the front radius and back rabbet seating are perfectly aligned to your hinges.
• Suitable for a range of door types—whether you’re working with solid wood, veneers, or composite cores—so you can standardize hinge prep across projects.
