Freud 03-144 1/4 Inch Single Flute Extended Reach Straight Router Bit

The Freud 03-144 is a 1/4-inch overall cutting diameter single-flute straight router bit engineered for high-speed material removal, rapid deep-pocket routing, and fast chip clearance. Built with a 1/4-inch shank, a 1-inch carbide height, and an extended 3-inch overall length, this single-cutter tool features an open single-flute design that maximizes waste ejection during deep passes. Tipped with TiCo™ Hi-Density Micrograin Carbide and coated with thermal-repelling Black I.C.E. (Industrial Cooling Element) technology, it operates at rotational speeds up to 24,000 RPM across CNC machinery, router tables, or handheld routers in solid hardwoods, softwoods, plywood, and wood composites.

Best Used For:

  • Rapid CNC Roughing Passes: Executing high-speed slot milling and rapid material clearing passes across sheet goods prior to final finishing routines.
  • Extended-Reach Deep Pocketing: Reaching deep interior recesses and thick panel stock using the 3-inch extended overall tool length.
  • Narrow High-Feed Grooving: Milling 1/4-inch wide dado grooves at aggressive feed rates without chip pack-up or thermal clogging.

Key Performance & Safety Features

  • Single-Flute Open Gullet Design: Maximizes chip clearance volume to enable faster linear feed rates and eliminate chip packing in deep cuts.
  • Black I.C.E. Thermal Coating: Industrial cooling element coating repels frictional heat and pitch buildup to preserve cutter edge sharpness.
  • 3-Inch Extended Overall Length: Extended tool length capacity provides reach for thick stock routing and deep interior template passes.
  • TiCo™ Hi-Density Micrograin Carbide: Custom-formulated titanium-cobalt micrograin carbide edges resist abrasive wear under continuous friction.
  • Plunge-Cut Tip Geometry: Precision end-ground face supports vertical drilling entry for starting internal grooves and blind mortises.
  • 24,000 RPM Maximum Speed Rating: Precision-balanced body geometry maintains stable operation at high rotational spindle speeds.

What's Included

  • (1) Freud 03-144 1/4" Single Flute Straight Router Bit with 1/4" Shank
