Precision Freud 1-1/4 Inch Ovolo Groove Router Bit 39-228 with 1/2 Inch Shank
The Freud 39-228 1-1/4-Inch Diameter Ovolo Groove Router Bit serves as an industrial-grade architectural profile cutting tool engineered to plunge directly into workpieces to route flat-bottom French Provincial grooves, panel accents, and edge profiles on solid hardwoods, softwoods, plywood, and wood composites. Manufactured with micrograin TiCo High-Density Carbide cutters treated with friction-reducing Red Perma-SHIELD non-stick finish, this heavy-duty 1/2-inch shank bit features a 3/8-inch radius, a 9/16-inch carbide height, and an 18,000 RPM maximum speed rating. Compatible with CNC automated routers, variable-speed router tables, and handheld plunge routers, this two-cutter decorative bit maintains sharp edge retention and chatter-free balance across cabinet doors, architectural molding, and custom furniture joinery.
Best Used For:
- French Provincial Cabinet Door Profiling: Plunging directly into cabinet panel faces to rout flat-bottom decorative ovolo channels and classical door accent profiles.
- Architectural Edge Beading & Round-Over Milling: Shaping smooth 3/8-inch radius edge profiles along tabletop perimeters, drawer fronts, and door casings when guided by a fence.
- CNC & Plunge Surface Fluting: Executing decorative panel channels, faux raised panel details, and accent grooves on automated CNC routers or plunge router setups.
Key Performance & Safety Features
- TiCo High-Density Micrograin Carbide: Proprietary titanium-cobalt carbide formulation maintains razor-sharp edges up to four times longer than standard carbide.
- Red Perma-SHIELD Thermal Barrier Coating: Non-stick red fluoropolymer coating insulates the bit body against heat buildup, pitch accumulation, and rust corrosion.
- Heavy-Duty 1/2-Inch Steel Shank: Provides maximum anti-flex structural rigidity and vibration-free stability during 1-1/4-inch diameter profile cuts.
- Precision Plunge-Cutting Center Geometry: Center-cutting carbide flutes permit smooth vertical plunge capability for stopped interior panel grooves.
- Computer-Balanced Dynamically Balanced Body: Dynamically balanced tool body eliminates vibration and chatter marks at regulated speeds up to 18,000 RPM.
- Dual-Flute Precision Shear Angle: Two precision-ground shear-angle carbide wings slice wood fibers cleanly to eliminate surface tear-out and grain burning.

Pro-Tip: When plunge-routing stopped French Provincial panel grooves on cabinet doors using a handheld plunge router, utilize a plunge base equipped with a turret depth stop. Making two progressive plunge steps down to your final 9/16-inch depth prevents tear-out at the entry point and allows efficient chip evacuation from the center channel.
