Achieve Deep, Clean Grooves with the Freud 3/8 Inch Double Flute Straight Router Bit

Elevate your woodworking precision with the Freud 04-126 3/8 Inch Double Flute Straight Bit. This professional-grade cutter is designed for general-purpose routing where depth and finish quality are paramount. Featuring a generous 1-1/4 inch carbide cutting height, this bit allows for deeper passes and extended reach compared to standard bits. It is crafted from Freud's exclusive TiCo Hi-Density Carbide, a proprietary formulation engineered to withstand high heat and maintain a razor-sharp edge up to four times longer than standard carbide cutters, ensuring reliable performance in hardwood, softwood, plywood, and abrasive composites.

The 04-126 is built for versatility and superior surface quality. Its computer-balanced double flute geometry utilizes precise hook and shear angles to slice cleanly through wood fibers, minimizing vibration and leaving a smooth finish that often requires no sanding. The carbide tips are relief-ground to facilitate safe and effective plunge cutting, making this tool essential for creating deep mortises, dados, and starting grooves in the center of a workpiece. Whether you are using a CNC machine, a hand-held router, or a table-mounted setup, this bit delivers the accuracy and durability required for fine joinery.

Key Features

  • TiCo Hi-Density Carbide: Specialized carbide blend offers maximum hardness and heat resistance for extended tool life.
  • Deep Cutting Capacity: 1-1/4 inch carbide height allows for deep grooving and mortising applications.
  • Double Flute Design: Two precision-ground edges ensure fast chip removal and a smooth, chatter-free finish.
  • Plunge Cutting Ready: Relieved tips allow for vertical drilling and starting grooves anywhere on the material.
  • 1/4 Inch Shank: Compatible with laminate trimmers, hand-held routers, and tabletop CNC machines.
  • Precision Geometry: Optimized shear angles reduce cutting resistance and prevent burning.

Pro-Tip: This bit features a long 1-1/4" cutting height on a 1/4" shank. To avoid tool deflection and potential breakage, never attempt to cut the full depth in a single pass. Instead, make multiple passes of approximately 1/4" to 3/8" depth at a time to ensure a clean, safe cut and prolong the life of the bit.
