Freud 11-180 1/2 Inch Single Flute Extended Reach Straight Router Bit

The Freud 11-180 is an extended-reach 1/2-inch overall cutting diameter single flute straight router bit engineered for rapid feed rates, deep mortise pocketing, and high-volume waste evacuation in thick lumber. Built with a heavy-duty 1/2-inch shank, an expansive 2-1/2-inch carbide cutting height, and a 4-3/8-inch overall length, this single-cutter tool features an open single-flute gullet that maximizes chip ejection volume to prevent thermal clogging. Tipped with TiCo™ Hi-Density Micrograin Carbide and computer-balanced for low vibration, it operates at spindle 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:

  • Deep Timber Mortise Joinery: Plunging into thick lumber stock to route deep 1/2-inch mortise channels for heavy furniture and structural framing.
  • Rapid CNC Roughing & Perimeter Cutouts: Executing high-speed perimeter cutout passes across thick panel sheet goods at elevated linear feed rates without chip packing.
  • Extended-Reach Deep Slot Milling: Machining deep dado channels and interior pockets in thick timber where standard bit lengths bottom out.

Key Performance & Safety Features

  • Single-Flute Open Gullet Design: Maximizes chip clearance volume to enable faster linear feed rates and prevent thermal friction buildup in deep cuts.
  • Expansive 2-1/2-Inch Carbide Cutting Height: Extended cutting edge length accommodates deep single-pass or multi-pass slotting and thick panel profiling.
  • 4-3/8-Inch Extended Overall Length: Extended tool body profile provides necessary clearance for deep mortising and hard-to-reach template routing.
  • TiCo™ Hi-Density Micrograin Carbide: Custom-formulated titanium-cobalt micrograin carbide edges resist heat degradation and preserve sharp edges.
  • Heavy-Duty 1/2-Inch Shank: Rigid 1/2-inch steel shank diameter minimizes tool flex, runout, and cutter vibration during high-feed rate cutting passes.
  • 24,000 RPM Maximum Speed Rating: Precision-engineered steel body maintains stable, chatter-free rotation across table-mounted, handheld, and CNC setups.

Pro-Tip: When routing deep 2-1/2-inch mortises with an extended single-flute bit, increase CNC linear feed speed slightly to maintain a clean chip load, preventing bit rubbing and thermal pitch buildup.
