WT-JGS Cove Box Diamond Router Bit with Bearing R12 (37 mm Head) – Vacuum Brazed Edge Fluting & Cove Profiling Bit (1/2” Shank)

The ToolDocker WT-JGS Cove Box Diamond Router Bit with Bearing (R12) is a vacuum-brazed edge shaping tool engineered for routing clean 12 mm radius cove edges, decorative stone mouldings, and fluted borders on engineered quartz, granite, marble, sintered stone, and porcelain slabs. Fitted with a sealed top guide ball bearing, wide 37 mm diamond profile head, and built-in cooling flutes, it allows fabricators to glide along templates and slab edges using portable routers for smooth, chatter-free shaping with minimal post-profiling hand polishing.

Key Features

• Smooth Top Ball Bearing Guide: Enables precise template following and edge guiding for manual handheld stone routers and CNC equipment without scratching the workpiece.

• Precision R12 (12 mm) Concave Radius: Calibrated for cutting uniform 12 mm cove profiles, rounded edge details, and decorative fluted borders.

• Slurry Discharge Flutes: Integrated clearance slits rapidly flush water and abrasive stone mud from the cutting zone, preventing diamond glazing and overheating.

• Vacuum-Brazed Diamond Bond: Coarse industrial diamond grit delivers fast feed rates and chip-free profiling on hard stone slabs.
