🛠️ A reverse glue joint router bit is a specialized woodworking tool designed to create interlocking profiles on the edges of boards, enhancing both alignment and bonding strength during glue-ups.

🔍 Key Features

• Interlocking Profile: Cuts a matching tongue-and-groove-like pattern on both edges of two boards. When reversed and joined, the profiles fit snugly together.
• Enhanced Glue Surface: Increases the surface area for glue, resulting in a stronger, more durable joint.
• Self-Aligning: The tapered or stepped profile helps draw boards into alignment during clamping, minimizing the need for additional planing or sanding.
• Versatile Use: Ideal for edge-joining panels, tabletops, doors, and furniture components. Works with hardwoods, softwoods, plywood, and composites.
• Router Compatibility: Can be used in table-mounted routers or CNC machines. Requires boards to be planed to uniform thickness and the bit centered precisely.

🧰 How It Works

1. Run one board through the router with the bit centered.
2. Flip the second board and run it through the same way.
3. The reversed profiles interlock perfectly, creating a flush, secure joint.

When clamping, apply enough pressure to seal the joint, but too much pressure may distort the wood.  This bit is featured on our DVD9.  Carbide tipped.
