Freud 12-122T 1/2 Inch Double Flute Straight Router Bit

The Freud 12-122T is a 1/2-inch overall cutting diameter double flute straight router bit engineered for deep mortise pocketing, thick stock dado jointing, and straight edge profiling. Built with a rigid 1/2-inch shank and an expansive 1-1/2-inch carbide cutting height, this 2-cutter tool features end-relieved tip geometry that enables clean, burn-free plunge entries into timber stock and composite panels. Tipped with TiCo™ Hi-Density Micrograin Carbide, protected by heat-resistant red Perma-SHIELD®, and computer-balanced to eliminate cutter chatter, 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:

  • Deep Mortise & Tenon Joinery: Plunging directly into timber stock to route clean 1/2-inch wide mortise channels for structural furniture and door assemblies.
  • Thick Stock Dado & Groove Milling: Machining 1/2-inch wide deep dado slots and cabinet rabbets across thick plywood sheets and solid hardwood panels.
  • Straight Edge Trimming & Template Profiling: Milling precise, square joint shoulders and straight edge profiles on deep workpiece borders in a single pass.

Key Performance & Safety Features

  • Perma-SHIELD® Non-Stick Coating: Protective red fluoropolymer coating repels pitch buildup, reduces drag friction, and Guards against thermal degradation.
  • Expansive 1-1/2-Inch Carbide Cutting Height: Deep carbide height capacity accommodates deep slotting, mortising, and thick panel edge trimming.
  • Heavy-Duty 1/2-Inch Shank: Rigid 1/2-inch steel shank diameter minimizes tool flex, runout, and cutter vibration during high-torque deep cuts.
  • TiCo™ Hi-Density Micrograin Carbide: Custom-formulated titanium-cobalt micrograin carbide tips maintain edge sharpness under continuous friction.
  • End-Relieved Plunge Cut Tip: Precision-ground end face geometry supports vertical drilling entry for starting internal grooves and blind mortises.
  • 24,000 RPM Maximum Speed Rating: Precision-engineered steel body maintains stable, chatter-free rotation across table-mounted, handheld, and CNC setups.
