Freud 12-136 5/8" Double Flute Straight Router Bit (1/2" Shank)

The Freud 12-136 5/8-inch double flute straight router bit routs precision grooves, clean dados, and mortises across dense hardwoods, softwoods, plywood, and composite sheet stock. Engineered with Freud's exclusive TiCo™ high-density carbide and precision-relieved plunge tips, this industrial-grade cutting accessory performs smooth plunge cuts and edge trimming up to a maximum rated rotational speed of 24,000 RPM. Outfitted with precision-ground shear angles that eliminate surface fuzzing, an anti-friction non-stick Perma-SHIELD® coating that prevents pitch buildup and lowers cutting temperatures, and a rigid 1/2-inch steel shank, it equips cabinetmakers, finish carpenters, and CNC machinists with mirror-smooth joinery passes across hand-held, router-table, and automated CNC machinery.

Best Used For:

  • Cabinetry Dado and Groove Milling: Cutting flat-bottom 5/8-inch dados, rabbets, and shelf housing grooves in cabinet side panels, plywood carcases, and solid hardwood casework.
  • Plunge Routing and Mortise Cutting: Executing clean vertical plunge entries for deep mortise-and-tenon joints, hardware recesses, and decorative template inlays without burning timber cores.
  • Precision Edge Trimming and CNC Profiling: Machining square, tearout-free edges and intricate internal cutouts across MDF, solid timber, particleboard, and composite panels.

Key Performance & Safety Features

  • TiCo™ Hi-Density Carbide: Proprietary titanium cobalt micrograin formulation retains razor sharpness significantly longer than standard commercial carbide grades.
  • Perma-SHIELD® Non-Stick Coating: Thermally stable barrier reduces rotational friction, sheds pitch and resin buildup, and resists corrosive chemical adhesives.
  • Precision-Relieved Plunge Tips: End-of-bit clearance geometry allows effortless, chatter-free vertical plunge routing without burning wood fibers.
  • Optimized Shear Angle Geometry: Two-flute double cutting profile slices through dense wood fibers smoothly to eliminate surface chipping and perimeter fuzzing.
  • Multi-Platform Rotational Balance: Dynamically balanced body rated up to 24,000 RPM provides vibration-free tracking in CNC machines, router tables, and hand-held plungers.
  • Heavy-Duty 1/2" Shank: Large-diameter solid alloy steel shank eliminates rotational deflection and provides maximum collet gripping security.

Pro-Tip: When routing deep 5/8-inch dados or mortises in dense hardwoods like maple or white oak, mill the groove across multiple incremental depth passes of no more than 1/4 inch per pass; staged depth passes maximize chip clearance, keep the carbide cutting edge cool, and produce mirror-flat groove bottoms.
