Experience Precision Routing and Long Life with the Freud 1/2 Inch Double Flute Straight Bit

Achieve professional-grade results in your woodworking projects with the Freud 04-131 1/2 Inch Double Flute Straight Bit. This versatile cutter is precision-engineered using Freud's exclusive TiCo Hi-Density Carbide, a specialized formula designed to deliver maximum hardness and resistance to heat. This superior material composition allows the bit to maintain a razor-sharp edge significantly longer than standard carbide cutters, ensuring clean, chatter-free cuts in hardwood, softwood, plywood, and composite materials.

Designed for flexibility, the 04-131 features a standard 1/4-inch shank, making it compatible with a wide range of hand-held routers, trim routers, and CNC machines. The computer-balanced double flute geometry includes precise hook and shear angles that slice efficiently through wood fibers to leave a smooth surface finish. Additionally, the carbide tips are relief-ground to facilitate safe and effective plunge cuts, making this tool ideal for cutting dados, rabbets, mortises, and intricate grooves.

Key Features

  • TiCo Hi-Density Carbide: Proprietary blend offers exceptional durability and extends cutting life in abrasive materials.
  • 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: Perfect for use in laminate trimmers, hand-held routers, and smaller CNC applications.
  • Versatile Application: Ideal for grooving, edge-routing, dadoing, and general stock removal.
  • Precision Geometry: Shear and hook angles are optimized to reduce cutting resistance and heat buildup.

Pro-Tip: When using bits with a smaller 1/4-inch shank, vibration can be a factor. To minimize chatter and ensure a cleaner cut, verify that the router collet is clean and in good condition, and always insert the shank fully into the collet (then pull it back slightly about 1/16") to ensure maximum grip.
