Master the Art of Indestructible Corner Joints with Precision Engineering

The Freud 99-034 Lock Miter Router Bit is the professional woodworker's secret to creating rock-solid, interlocking 90-degree corner joints. This high-performance bit is specifically designed to maximize surface area for glue bonding, resulting in a joint that is significantly stronger than a standard miter. By routing one workpiece horizontally on the router table and the matching piece in a vertical position, you achieve a self-aligning joint that eliminates the frustration of slipping pieces during glue-up.

Engineered for use with 1/2-inch to 1-inch stock, this bit is perfect for high-end cabinetry, column construction, and furniture making. It features Freud’s exclusive Perma-SHIELD® non-stick coating, which reduces friction and pitch buildup to ensure cooler cuts and a longer tool life. Whether you are working with hardwoods, softwoods, plywood, or composites, the precision-ground carbide teeth provide a flawless finish that requires minimal sanding.

Key Features

  • Unmatched Joint Strength: Creates incredibly strong interlocking 90° corners with massive glue surface area.
  • Self-Aligning Design: Simplifies assembly by locking pieces into place, preventing movement during clamping.
  • Perma-SHIELD® Coating: Protects the bit from heat, prevents resin buildup, and resists corrosion.
  • Versatile Material Range: Optimized for hardwood and softwood, but also excels with plywood and composites.
  • Industrial Precision: Expertly balanced to run at speeds up to 12,000 RPM for clean, chatter-free results.
  • Heavy-Duty Shank: 1/2" shank provides maximum stability and safety for large-diameter routing.

Pro-Tip: Setup is critical with lock miter bits. For the most accurate joint, ensure your material is perfectly flat and thickness-planed. Use a scrap piece of the exact same thickness to dial in your fence and bit height; when the joint closes perfectly with both faces flush, you are ready for your final workpiece.
