Achieve Precision Reach and Flawless Cuts with the Freud 1/4 Inch Double Flute Straight Router Bit

Unlock versatile routing capabilities with the Freud 04-109 1/4 Inch Double Flute Straight Bit. Designed with an extended overall length of 2-7/8 inches, this bit provides the extra reach needed for deeper grooving tasks and template work that standard bits cannot handle. It is crafted from Freud's exclusive TiCo Hi-Density Carbide, a specialized formulation that delivers maximum hardness and edge retention. This premium construction ensures that the bit stays sharp significantly longer, providing clean, chatter-free cuts in hardwood, softwood, plywood, and abrasive composite materials.

The 04-109 is engineered for both efficiency and finish quality. Its computer-balanced double flute geometry features precise hook and shear angles that slice efficiently through wood fibers, leaving a smooth surface finish that requires minimal sanding. The carbide tips are also relief-ground to facilitate safe and effective plunge cuts, making this tool ideal for creating dados, rabbets, mortises, and intricate grooves. Whether you are using a CNC machine, a hand-held router, or a table-mounted setup, this bit offers the professional precision and durability you expect from Freud.

Key Features

  • TiCo Hi-Density Carbide: Proprietary blend offers exceptional durability and extends cutting life in tough materials.
  • Extended Reach: 2-7/8 inch overall length allows for deeper grooving and access to hard-to-reach areas.
  • Double Flute Design: Two precision-ground edges ensure fast chip removal and a smooth, clean finish.
  • Plunge Cutting Ready: Tips are relieved to allow for vertical drilling and starting grooves in the center of the workpiece.
  • 1/4 Inch Shank: Compatible with laminate trimmers, hand-held routers, and CNC machines.
  • Precision Geometry: Optimized shear and hook angles reduce cutting resistance and heat buildup.

Pro-Tip: This bit features a longer overall length (2-7/8") than standard straight bits. While this provides excellent reach, the 1/4" diameter makes it susceptible to deflection if pushed too hard. For the best accuracy and to prevent breakage, always take multiple shallow passes rather than attempting to cut the full depth at once.
