Freud Router Bit 22-121 7/16 Inch Dia 1/4 Inch Shank Dovetail (24000 RPM 8 Degree TiCo Carbide Perma-SHIELD Cabinet Furniture Drawer Jointing Tool)

Precision Freud 7/16 Inch 8-Degree Dovetail Router Bit 22-121 with 1/4 Inch Shank

The Freud 22-121 7/16-Inch Diameter Dovetail Router Bit serves as an industrial-grade mechanical jointing tool engineered to execute precise 8-degree angled dovetail pins and tails for high-strength drawer box construction and cabinetry. Manufactured with micrograin TiCo High-Density Carbide cutters treated with friction-reducing Red Perma-SHIELD non-stick finish, this 1/4-inch shank bit features a 5/8-inch carbide cutting height, 2-3/8-inch overall length, and a 24,000 RPM maximum speed rating. Compatible with CNC machinery, handheld portable routers, and router table jig systems, this dual-flute shear-angle bit slices wood fibers cleanly to eliminate grain tear-out across solid hardwoods, softwoods, cabinet plywood, and composite substrates.

Best Used For:

• Commercial Drawer Box Construction: Routing tight, gap-free 8-degree interlocking dovetail joints on solid hardwood and plywood drawer sides.
• Fine Furniture & Cabinet Joinery: Milling decorative structural corner joints on custom jewelry boxes, cabinet cases, and heirloom furniture.
• Jig-Guided Dovetail Template Operations: Interfacing with standard mechanical dovetail jigs to duplicate consistent pin-and-tail profiles across production runs.

Key Performance & Safety Features

• Precision 8-Degree Cutting Angle: Machined to exact angular tolerances for flawless fitment with popular mechanical dovetail jig templates.
• TiCo High-Density Micrograin Carbide: Proprietary titanium-cobalt carbide formulation maintains razor-sharp cutting edges up to four times longer than standard carbide.
• Red Perma-SHIELD Thermal Barrier Coating: Non-stick fluoropolymer coating insulates the bit body against heat buildup, pitch accumulation, and rust corrosion.
• Precision Shear-Angle Flute Geometry: Cutters are positioned at an angle to slice wood fibers smoothly, preventing bottom-corner tear-out.
• High-Speed 24,000 RPM Stability Rating: Computer-balanced bit body ensures vibration-free operation and clean chip clearance at maximum router speeds.
• Multi-Platform Router Compatibility: Engineered for secure chuck mounting across CNC spindles, handheld plunge routers, and router table setups.

Technical Specifications

Pro-Tip: When routing deep dovetail pins in dense hardwoods like maple or oak, pre-groove the joint paths using a standard straight bit slightly smaller than the 7/16-inch dovetail base diameter. Removing the center waste stock first prevents heat buildup, extends carbide tip life, and stops bit chatter inside the joint recess.
