Freud Straight Router Bit 12-140 5/8 Inch Double Flute (1/2 Inch Shank TiCo Carbide 24000 RPM 1-1/2 Cut Length Deep Mortising Wood CNC)

Freud 12-140 5/8 Inch Double Flute Deep Cut Straight Router Bit

The Freud 12-140 is an extended-reach 5/8-inch overall cutting diameter double flute straight router bit engineered to execute deep mortise pocketing, thick stock dado jointing, and heavy material removal. Built with a heavy-duty 1/2-inch shank and an extended 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 and computer-balanced to eliminate cutter vibration, 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 Timber Mortise Joinery: Plunging directly into thick lumber stock to route clean 5/8-inch wide mortise channels for heavy furniture and architectural assemblies.
• Thick Stock Dado & Groove Milling: Machining 5/8-inch wide deep dado slots, rabbet joints, and shelf channels across thick plywood sheets and solid hardwood panels.
• Deep CNC Interior Pocketing: Executing extended-depth interior cutouts and recessed hardware pockets in thick wood panels where standard bit lengths fall short.

Key Performance & Safety Features

• Expansive 1-1/2-Inch Carbide Cutting Height: Extended cutting edge length accommodates deep single-pass or multi-pass slotting and thick panel edge profiling.
• TiCo™ Hi-Density Micrograin Carbide: Custom-formulated titanium-cobalt micrograin carbide edges withstand high cutting heat and maintain long edge life.
• Heavy-Duty 1/2-Inch Shank: Rigid 1/2-inch steel shank diameter minimizes tool flex, runout, and cutter chatter during deep routing passes.
• End-Relieved Plunge Cut Tip: Precision-ground end face geometry supports vertical drilling entry for starting internal grooves and blind mortises.
• Dual-Flute Precision Balance: Computer-balanced twin cutters distribute chip load evenly to produce smooth sidewalls and flat bottom cuts.
• 24,000 RPM Maximum Speed Rating: Precision-engineered steel body maintains stable, chatter-free rotation across table-mounted, handheld, and CNC setups.
