Achieve Flawless Grooves and Precision Mortises with the Freud 3/8 Inch Double Flute Straight Router Bit

Take your woodworking precision to the next level with the Freud 12-116T 3/8 Inch Double Flute Straight Bit. Engineered for professional-grade performance, this bit features Freud's exclusive TiCo Hi-Density Carbide, a special formulation that delivers maximum hardness and resistance to heat. This advanced material composition ensures the bit retains a razor-sharp edge significantly longer than standard steel or carbide cutters, making it perfect for rigorous general-purpose routing, edge-routing, and grooving in hardwood, softwood, plywood, and composites.

The design of this bit is centered on versatility and finish quality. It utilizes a computer-balanced double flute geometry with precise hook and shear angles to slice cleanly through wood fibers, leaving a smooth surface that requires minimal sanding. The carbide tips are relief-ground, allowing for efficient chip clearance and safe vertical plunge cuts, which is essential for stopping and starting grooves or creating mortises. Supported by a robust 1/2-inch shank for added stability and reduced vibration, this bit performs exceptionally well in CNC, hand-held, and table-mounted routers.

Key Features

  • TiCo Hi-Density Carbide: Proprietary carbide blend withstands high heat and extends cutting life in abrasive materials.
  • Double Flute Design: Two precision-ground cutting edges ensure a balanced cut and a superior surface finish.
  • Plunge Cutting Capability: Relieved tips allow for effective vertical drilling and mortising operations.
  • Perma-SHIELD Coating: Non-stick red coating reduces friction, heat buildup, and pitch accumulation.
  • Broad Compatibility: Engineered for safe operation in CNC, hand-held, and table-mounted routers.
  • Heavy-Duty Shank: 1/2-inch shank minimizes chatter and vibration for cleaner, more accurate cuts.

Pro-Tip: When using a 3/8" bit to cut deep grooves or mortises, avoid cutting the full depth in a single pass to prevent tool breakage and burning. Instead, make multiple passes, removing no more than 1/4" to 3/8" of material depth at a time for the cleanest results.
