Create Intricate Patterned Grooves with Precision Template Routing

Add depth and classical elegance to your furniture and millwork projects with the Freud 39-502 3/4" Diameter Top Bearing Cove and Bead Groove Router Bit. Designed specifically for template work, this specialized bit features a shank-mounted ball bearing that allows you to trace a pattern placed on top of your workpiece. This configuration is perfect for plunging and routing decorative flat-bottom grooves with a classic cove and bead profile into the face of cabinet doors, drawer fronts, and architectural details, ensuring every curve matches your design perfectly.

Crafted for professional durability, the 39-502 is equipped with Freud’s exclusive TiCo™ Hi-Density Carbide tips. This micrograin formula ensures the cutting edges stay razor-sharp longer, even when routing through tough hardwoods, plywood, and abrasive composites. The bit is finished with the signature Red Perma-SHIELD® Non-Stick Coating, which dramatically reduces friction, heat buildup, and resin accumulation. Whether you are using a hand-held router or a table-mounted setup, this tool delivers smooth, burn-free cuts that require minimal sanding.

Key Features

  • Top-Bearing Design: Shank-mounted bearing is ideal for following templates placed on top of the workpiece.
  • Decorative Profile: Cuts a classic cove and bead groove with a flat bottom for architectural detail.
  • TiCo™ Hi-Density Carbide: Proprietary blend offers superior edge retention and cutting life.
  • Perma-SHIELD® Coating: Non-stick red coating protects against heat, rust, and pitch buildup.
  • Versatile Compatibility: Safe for use in hand-held and table-mounted portable routers.

Pro-Tip: When using top-bearing bits for template work, always double-check that your template is securely fastened to the top of your workpiece. Because the bearing rides on the template, any movement will be instantly transferred to the cut. For deep grooves, make multiple passes, increasing the depth slightly each time, rather than trying to rout the full profile depth in a single pass.
