Achieve Superior Finish and Precision with the Freud 13/16 Inch Double Flute Straight Router Bit

Enhance your woodworking precision with the Freud 04-144 13/16 Inch Double Flute Straight Bit. This professional-grade cutter is crafted using Freud's exclusive TiCo Hi-Density Carbide, a proprietary formulation designed to withstand high operating temperatures and maintain a sharp cutting edge up to four times longer than standard carbide bits. Featuring a versatile 1/4-inch shank, this tool is compatible with a wide array of hand-held routers and smaller CNC machines, ensuring reliable performance in hardwood, softwood, plywood, and abrasive composite materials.

The 04-144 is engineered for both efficiency and finish quality. Its computer-balanced double flute geometry includes precision-ground hook and shear angles that slice cleanly through wood fibers, significantly reducing vibration and leaving a smooth surface that requires minimal sanding. The bit also features relief-ground tips, allowing for safe and effective plunge cutting—perfect for starting grooves in the center of a workpiece or creating precise mortises. Whether you are performing general stock removal, edge-routing, or cutting wide dados, this bit delivers the accuracy and durability professionals demand.

Key Features

  • TiCo Hi-Density Carbide: Specialized carbide blend offers maximum hardness and heat resistance for extended tool life.
  • Double Flute Geometry: Two precision cutting edges ensure fast chip removal and a smooth, chatter-free finish.
  • Plunge Cutting Capability: Relieved tips allow for vertical drilling and starting grooves anywhere on the material.
  • 1/4 Inch Shank: Ideal for use in laminate trimmers, hand-held routers, and tabletop CNC machines.
  • Precision Shear Angles: Optimized geometry reduces cutting resistance and prevents burning on the workpiece.
  • Versatile Application: Perfect for grooving, dadoing, edge-routing, and general material removal.

What's Included:

  • (1) 13/16 In. Double Flute Straight Bit with 1/4 In. Shank (Model 04-144)

Pro-Tip: When using a large diameter bit (13/16") on a smaller 1/4" shank, stability is crucial. To avoid shank flex and vibration, make multiple shallow passes (approximately 1/8" to 1/4" deep per pass) rather than attempting to cut the full depth at once. This ensures a cleaner finish and safer operation.
