Experience Maximum Stability and Precision with the Freud 1/4 Inch Straight Bit on a 1/2 Inch Shank

Eliminate vibration and achieve incredibly clean grooves with the Freud 12-100 1/4 Inch Double Flute Straight Router Bit. This tool offers a distinct advantage for detail work: it combines a delicate 1/4-inch cutting diameter with a heavy-duty 1/2-inch shank. This "over-shanked" design provides superior rigidity compared to standard 1/4-inch shank bits, drastically reducing chatter and deflection. The result is a flawless finish and perfectly straight walls, making it the ideal choice for routing dadoes for drawer bottoms, inlay work, and intricate joinery in hardwood, softwood, plywood, and composites.

Engineered for professional performance, the 12-100 is constructed with Freud's exclusive TiCo Hi-Density Carbide. This proprietary micro-grain formula is designed to hold a razor-sharp edge longer, even when cutting abrasive materials. The computer-balanced double flute geometry features precise hook and shear angles that slice cleanly through wood fibers rather than tearing them, ensuring a smooth surface that requires minimal sanding. With end-relieved tips that allow for efficient plunge cutting, this bit is a versatile performer for CNC machines, router tables, and hand-held routing tasks.

Key Features

  • High-Stability Design: 1/2-inch shank provides maximum rigidity for the 1/4-inch cutter, reducing vibration.
  • TiCo Hi-Density Carbide: Proprietary blend offers superior hardness and heat resistance for extended tool life.
  • Double Flute Geometry: Two precision-ground edges ensure fast chip removal and a smooth finish.
  • Plunge Ready: End-relieved tips allow for vertical drilling and starting cuts in the center of a panel.
  • Versatile Compatibility: Safe for use in CNC, table-mounted, and hand-held routers.
  • Multi-Material Cutting: excels in hardwood, softwood, plywood, and composite materials.
  • Shear Angle Design: Optimized geometry produces clean cuts with minimal tear-out.

Pro-Tip: Even with a sturdy 1/2" shank, a 1/4" cutter head is small and can heat up quickly if pushed too hard. To extend the life of this bit and prevent burning your wood, use a faster RPM setting but maintain a moderate feed rate. If cutting a groove deeper than 1/4", make multiple passes rather than trying to cut the full depth at once.
