Freud Straight Router Bit 12-108 3/8 Inch Double Flute (1/2 Inch Shank TiCo Carbide 24000 RPM Grooving Dadoes Mortising Plywood Hardwood)

Freud 12-108 3/8 Inch Double Flute Straight Router Bit

The Freud 12-108 is a 3/8-inch overall cutting diameter double flute straight router bit engineered for precision dado slotting, rabbeting, spline joinery, and hardware mortising. Constructed with a heavy-duty 1/2-inch shank and a 1-inch carbide cutting height, this 2-cutter tool utilizes an over-shanked design that eliminates tool flex and cutter chatter in deep passes. Tipped with TiCo™ Hi-Density Micrograin Carbide, computer-balanced for low-vibration operation, and featured with end-relieved tip geometry for clean plunge entries, 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:

• 3/8-Inch Dado & Groove Milling: Machining rigid 3/8-inch wide dado channels, shelf slots, and cabinet joinery grooves without chatter marks or edge tearout.
• Rabbet & Spline Joint Fabrication: Cutting precise square joint shoulders and spline channels in solid hardwood cabinet frames and casework.
• Plunge Pocketing & Hardware Mortising: Diving directly into timber stock to execute clean interior pockets, lockset recesses, and blind mortise slots.

Key Performance & Safety Features

• Heavy-Duty 1/2-Inch Over-Shank: Rigid 1/2-inch shank step-up design provides superior mechanical stability and eliminates tool deflection for the 3/8-inch cutter head.
• TiCo™ Hi-Density Micrograin Carbide: Custom-formulated titanium-cobalt micrograin carbide edges resist cutting heat and maintain long edge life.
• End-Relieved Plunge Cut Tip: Precision-ground end face tip relief allows 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.
• Optimized Hook & Shear Angles: Shear-angled cutting geometry slices cleanly through wood fibers to minimize chip tearout and thermal burning.
• 24,000 RPM Maximum Speed Rating: Precision-engineered steel body maintains stable, chatter-free rotation across table-mounted, handheld, and CNC setups.
