TD-JGS Multi Arc Bit 4 (46 mm Cutting Height) – Vacuum Brazed Architectural Stepped Drop & Bullnose Edge Profiling Router Bit (1/2” Shank)

The ToolDocker TD-JGS Multi Arc Bit (No. 4) is a heavy-duty vacuum-brazed architectural stone profiling router bit designed for cutting deep multi-tier curves, wide drops, and sculpted cove contours on engineered quartz, granite, marble, sintered stone, and porcelain slabs. Featuring an expansive 48.5 mm top rim, a sculpted 11 mm center waist, and a full 46 mm cutting profile height, it delivers smooth, symmetrical, and ornate edge transitions on luxury countertops, fireplace surrounds, and custom stone installations with minimal secondary hand polishing.

Key Features

• Multi-Tier Architectural Drop Profile: Built with a broad 48.5 mm upper disc transitioning into a stepped shoulder, deeply recessed 11 mm cove neck, and bottom bullnose flare.

• Deep 46 mm Cutting Height: Optimized for complete single-pass decorative profiling across extra-thick 4 cm stone slabs, laminated edge build-ups, and architectural moldings.

• Vacuum-Brazed Diamond Bond: Coarse industrial diamond particles fused to hardened tool steel deliver high stock removal rates and chip-free edge transitions.

• Rigid 1/2″ (12.7 mm) Shank: Solid tool-steel shank resists vibration, deflection, and chatter under heavy profiling torque.

• Mandatory Continuous Water Cooling: Operates with flood coolant or continuous water mist to flush stone sludge and prevent diamond glazing.
