Execute Custom Joinery with the Freud 11/16 Inch Straight Router Bit

Achieve exact dimensions for custom woodworking projects with the Freud 12-148 11/16 Inch Double Flute Straight Bit. This specific diameter is essential for creating precise grooves, dadoes, and mortises that require an 11/16-inch width—often necessary for specific hardware installations, shelf standards, or joining undersized stock where a standard 3/4-inch bit would be too loose. Anchored by a heavy-duty 1/2-inch shank, this tool provides the stability and mass required to dampen vibration, ensuring smooth, chatter-free cuts even when routing dense hardwoods or abrasive composites.

Engineered for professional longevity, the 12-148 is crafted from Freud's exclusive TiCo Hi-Density Carbide. This proprietary blend is formulated to resist heat and wear, keeping the cutting edges sharp up to four times longer than standard carbide bits. The bit features a computer-balanced double flute geometry with precision-ground hook and shear angles. This design slices cleanly through wood fibers to produce a superior finish that minimizes sanding time. With end-relieved tips that facilitate efficient plunge cutting, this bit is equally effective in CNC machinery, router tables, and hand-held routing applications.

Key Features

  • Specific 11/16 Inch Diameter: Ideal for custom joinery, hardware mortises, and specific groove width requirements.
  • TiCo Hi-Density Carbide: Specialized carbide formulation resists heat and corrosion for maximum tool life.
  • Heavy-Duty Shank: 1/2-inch shank ensures exceptional stability and reduces vibration during operation.
  • Plunge Ready: Relieved tip geometry allows for vertical drilling and starting pockets in the center of the material.
  • Clean Finishes: Precision shear angles reduce tearing and produce smooth, burn-free edges.
  • Versatile Compatibility: Safe for use in CNC, table-mounted, and hand-held routers.
  • Perma-SHIELD Coating: Non-stick coating reduces drag and prevents pitch and resin buildup.

Pro-Tip: The 11/16" size is often used for specific shelf standards or undersized plywood dadoes. However, always use calipers to measure your actual material or hardware thickness before routing. If the fit is slightly too tight, you can sand the groove; if it is too loose, the joint will be weak. This bit provides a precise alternative to standard 3/4" bits for tighter fits.
