Freud 03-136 1/4 Inch Single Flute Straight Router Bit

The Freud 03-136 is a 1/4-inch overall cutting diameter single-flute straight router bit engineered for rapid material removal, fast CNC slotting, and efficient chip evacuation in production shop environments. Built with a 1/4-inch shank and a 3/4-inch carbide cutting height, this single-cutter tool features an open single-flute design that maximizes waste ejection during aggressive feed passes. Tipped with TiCo™ Hi-Density Micrograin Carbide and sealed with thermal-repelling Black I.C.E. (Industrial Cooling Element) coating, it operates at rotational speeds up to 24,000 RPM across CNC machinery, router tables, or handheld routers in solid hardwoods, softwoods, plywood, and abrasive composite panels.

Best Used For:

  • Rapid CNC Sheet Nesting & Cutouts: Executing high-speed perimeter cutout passes and rapid slotting across cabinet sheet goods without chip packing.
  • High-Feed Dado & Groove Milling: Machining 1/4-inch wide dado channels and joinery slots at elevated linear feed rates without heat buildup.
  • Plunge Pocketing & Interior Routing: Plunging vertically into timber stock to route clean interior cutouts, wire channels, and blind mortises.

Key Performance & Safety Features

  • Single-Flute Open Gullet Design: Maximizes chip clearance volume to enable faster linear feed rates and eliminate chip loading in deep cuts.
  • Black I.C.E. Thermal Coating: Industrial cooling element coating repels frictional heat buildup and prevents pitch accumulation to preserve cutter edge sharpness.
  • TiCo™ Hi-Density Micrograin Carbide: Custom-formulated titanium-cobalt micrograin carbide edges resist abrasive wear under continuous friction.
  • End-Relieved Plunge Cut Tip: Precision end-ground face supports vertical drilling entry for starting internal grooves and blind mortises.
  • Versatile 1/4-Inch Shank Compatibility: Mounts securely in standard 1/4-inch router collets across CNC spindles, router tables, and handheld trim routers.
  • 24,000 RPM Maximum Speed Rating: Precision-balanced body geometry maintains stable operation at high rotational spindle speeds.

  • (1) Freud 03-136 1/4" Single Flute Straight Router Bit with 1/4" Shank

Pro-Tip: Increase your linear feed speed when running single-flute bits on CNC machinery; single-flute cutters require higher feed rates per RPM to maintain adequate chip load and prevent material friction burning.
