Master Precision Template Routing with Freud’s Down-Shear Mortising Excellence

The Freud 16-504 Top Bearing Mortising Router Bit is the ultimate solution for woodworkers who demand flawless, splinter-free results when recessing hinges, hardware, or cutting deep dadoes. Engineered with a specialized down-shear design, this bit pushes wood fibers downward during the cut to eliminate top-surface tear-out on delicate veneers, plywood, and solid hardwoods. The integrated top-mounted ball bearing allows you to follow templates and routing jigs with absolute precision, making it an indispensable tool for high-end cabinetry and custom furniture projects.

Constructed with Freud’s TiCo™ High-Density Carbide, this bit is built for industrial durability and sustained sharpness. It features deep center gullets designed for maximum material removal, allowing you to clear waste quickly without the risk of chip loading or overheating. To ensure a longer life and smoother operation, the 16-504 is treated with Perma-SHIELD® non-stick coating, which reduces friction and prevents resin or pitch buildup. Whether you are using a portable hand-held router, a table-mounted setup, or a CNC machine, this bit delivers the accuracy required for professional joinery and hardware installation.

Key Features

  • Down-Shear Angle: Eliminates top-surface splintering by pushing wood fibers down for a clean, professional finish.
  • Precision Top Bearing: Optimized for template-guided routing and popular woodworking jigs.
  • Deep Center Gullets: Facilitates rapid chip evacuation and maximum material removal without clogging.
  • Perma-SHIELD® Coating: Non-stick red coating protects against heat, friction, and pitch buildup.
  • TiCo™ High-Density Carbide: Specially formulated carbide provides a sharper edge and significantly longer cutting life.
  • Universal Compatibility: Perfect for use in CNC, hand-held, and table-mounted portable routers.
  • Versatile Application: Ideal for mortising hinges, hardware recesses, clean grooves, and precise dadoes.

Pro-Tip: When using a template with this top-bearing bit, ensure your template is thick enough (at least 1/4" to 1/2") to provide a secure surface for the bearing to follow. For the cleanest mortises, clear out the bulk of the waste with a Forstner bit or a standard straight bit first; this allows the mortising bit to focus on the final edges, reducing heat buildup and extending the life of your carbide cutters.
