About this product
Precision Freud 2-1/4 Inch Ovolo Groove Router Bit 39-236 with 1/2 Inch Shank
The Freud 39-236 2-1/4-Inch Diameter Ovolo Groove Router Bit operates as an industrial-grade architectural profile cutting tool engineered to plunge directly into workpieces to route wide, flat-bottom French Provincial grooves, panel accents, and edge round-over profiles into solid hardwoods, softwoods, plywood, and wood composites. Manufactured with micrograin TiCo High-Density Carbide cutters treated with friction-reducing Red Perma-SHIELD non-stick coating, this heavy-duty 1/2-inch shank bit features a 7/8-inch radius, a 1-1/8-inch carbide height, and a 16,000 RPM maximum speed rating. Compatible with CNC automated routers, variable-speed router tables, and heavy handheld plunge routers, this two-cutter decorative bit maintains sharp edge retention and chatter-free balance across custom cabinetry, architectural molding, and fine furniture joinery.
Best Used For:
- French Provincial Cabinet Door Profiling: Plunging directly into cabinet panel faces to rout wide, flat-bottom decorative ovolo channels and classical door profiles.
- Architectural Edge Beading & Round-Over Milling: Shaping smooth 7/8-inch radius edge profiles along tabletop perimeters, mantelpieces, and door casings when guided by a fence.
- CNC & Plunge Surface Fluting: Executing wide architectural panel channels, faux raised panel profiles, and decorative grooves on automated CNC routers or plunge router setups.
Key Performance & Safety Features
- TiCo High-Density Micrograin Carbide: Custom formulation titanium-cobalt carbide cutters retain razor-sharp edges significantly longer than standard carbide when milling dense hardwoods.
- 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 wide 2-1/4-inch diameter profile cuts.
- Precision Plunge-Cutting Center Geometry: Center-cutting carbide flutes permit smooth direct vertical plunging for stopped interior panel grooves and blind channels.
- Computer-Balanced Dynamically Balanced Body: Dynamically balanced tool body eliminates vibration and chatter marks at regulated speeds up to 16,000 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.

When plunge-routing deep French Provincial panel profiles into dense cherry or maple, take two or three progressive depth passes rather than trying to cut the entire 1-1/8 inch profile at once to prevent chatter marks and motor bog-down.
